Subject: x86: UV BAU and nodes with no memory

This patch fixes BAU initialization for systems containing
nodes with no memory and for systems with non-consecutive
node numbers.

Fixes and clarifies situations where pnode should be used instead
of node id.

Tested on the UV hardware simulator.

Subject: x86: UV BAU messaging timeouts

This patch replaces a 'nop' uv_enable_timeouts() in the
UV TLB shootdown code. (somehow, long ago that function got
eviscerated)

If any cpu in the destination node does not get interrupted by the
message and post completion in a reasonable time the hardware
should respond to the sender with an error.  This function
enables such timeouts.

Tested on the UV hardware simulator.

Subject: net/9p: set correct stat size when sending Twstat messages

The 9P2000 Twstat message requires the size of the stat structure to be
specified. Currently the 9p code writes zero instead of the actual size.
This behavior confuses some of the file servers that check if the size is
correct.

This patch adds a new function that calculcates the stat size and puts the
value in the appropriate place in the 9P message.

Subject: net/9p: return error when p9_client_stat fails

p9_client_stat function doesn't return correct value if it fails.
p9_client_stat should return ERR_PTR of the error value when it fails.
Instead, it always returns a value to the allocated p9_wstat struct even
when it is not populated correctly.

This patch makes p9_client_stat to handle failure correctly.

Subject: net/9p: handle correctly interrupted 9P requests

Currently the 9p code crashes when a operation is interrupted, i.e. for
example when the user presses ^C while reading from a file.

This patch fixes the code that is responsible for interruption and flushing
of 9P operations.

Subject: xfs: validate log feature fields correctly

If the large log sector size feature bit is set in the
superblock by accident (say disk corruption), the then
fields that are now considered valid are not checked on
production kernels. The checks are present as ASSERT
statements so cause a panic on a debug kernel.

Change this so that the fields are validity checked if
the feature bit is set and abort the log mount if the
fields do not contain valid values.

Subject: xfs: fix double free of inode

If we fail to initialise the VFS inode in inode_init_always(),
it will call ->delete_inode internally resulting in the inode being
freed. Hence we need to delay the call to inode_init_always()
until after the XFS inode is sufficient set up to handle a
call to ->delete_inode, and then if that fails do not touch
the inode again at all as it has been freed.

Subject: xfs: prevent unwritten extent conversion from blocking I/O completion

Unwritten extent conversion can recurse back into the filesystem due
to memory allocation. Memory reclaim requires I/O completions to be
processed to allow the callers to make progress. If the I/O
completion workqueue thread is doing the recursion, then we have a
deadlock situation.

Move unwritten extent completion into it's own workqueue so it
doesn't block I/O completions for normal delayed allocation or
overwrite data.

Subject: xfs: inform the xfsaild of the push target before sleeping

When trying to reserve log space, we find the amount of space
we need, then go to sleep waiting for space. When we are
woken, we try to push the tail of the log forward to make
sure we have space available.

Unfortunately, this means that if there is not space available, and
everyone who needs space goes to sleep there is no-one left to push
the tail of the log to make space available. Once we have a thread
waiting for space to become available, the others queue up behind
it in a FIFO, and none of them push the tail of the log.

This can result in everyone going to sleep in xlog_grant_log_space()
if the first sleeper races with the last I/O that moves the tail
of the log forward. With no further I/O tomove the tail of the log,
there is nothing to wake the sleepers and hence all transactions
just stop.

Fix this by making sure the xfsaild will create enough space for the
transaction that is about to sleep by moving the push target far
enough forwards to ensure that that the curent proceeees will have
enough space available when it is woken. That is, we push the
AIL before we go to sleep.

Because we've inserted the log ticket into the queue before we've
pushed and gone to sleep, subsequent transactions will wait behind
this one. Hence we are guaranteed to have space available when we
are woken.

Subject: xfs: use xfs_sync_inodes() for device flushing

Currently xfs_device_flush calls sync_blockdev() which is
a no-op for XFS as all it's metadata is held in a different
address to the one sync_blockdev() works on.

Call xfs_sync_inodes() instead to flush all the delayed
allocation blocks out. To do this as efficiently as possible,
do it via two passes - one to do an async flush of all the
dirty blocks and a second to wait for all the IO to complete.
This requires some modification to the xfs-sync_inodes_ag()
flush code to do efficiently.

Subject: xfs: make inode flush at ENOSPC synchronous

When we are writing to a single file and hit ENOSPC, we trigger a background
flush of the inode and try again.  Because we hold page locks and the iolock,
the flush won't proceed until after we release these locks. This occurs once
we've given up and ENOSPC has been reported. Hence if this one is the only
dirty inode in the system, we'll get an ENOSPC prematurely.

To fix this, remove the async flush from the allocation routines and move
it to the top of the write path where we can do a synchronous flush
and retry the write again. Only retry once as a second ENOSPC indicates
that we really are ENOSPC.

This avoids a page cache deadlock when trying to do this flush synchronously
in the allocation layer that was identified by Mikulas Patocka.

Subject: xfs: block callers of xfs_flush_inodes() correctly

xfs_flush_inodes() currently uses a magic timeout to wait for
some inodes to be flushed before returning. This isn't
really reliable but used to be the best that could be done
due to deadlock potential of waiting for the entire flush.

Now the inode flush is safe to execute while we hold page
and inode locks, we can wait for all the inodes to flush
synchronously. Convert the wait mechanism to a completion
to do this efficiently. This should remove all remaining
spurious ENOSPC errors from the delayed allocation reservation
path.

This is extracted almost line for line from a larger patch
from Mikulas Patocka.

Subject: xfs: flush delayed allcoation blocks on ENOSPC in create

If we are creating lots of small files, we can fail to get
a reservation for inode create earlier than we should due to
EOF preallocation done during delayed allocation reservation.
Hence on the first reservation ENOSPC failure flush all the
delayed allocation blocks out of the system and retry.

This fixes the last commonly triggered spurious ENOSPC issue
that has been reported.

Subject: xfs: remove xfs_flush_space

The only thing we need to do now when we get an ENOSPC condition during delayed
allocation reservation is flush all the other inodes with delalloc blocks on
them and retry without EOF preallocation. Remove the unneeded mess that is
xfs_flush_space() and just call xfs_flush_inodes() directly from
xfs_iomap_write_delay().

Also, change the location of the retry label to avoid trying to do EOF
preallocation because we don't want to do that at ENOSPC. This enables us to
remove the BMAPI_SYNC flag as it is no longer used.

2.06 architecture process.

Subject: powerpc: Add support for early tlbilx opcode

During the ISA 2.06 development the opcode for tlbilx changed and some
early implementations used to old opcode.  Add support for a MMU_FTR
fixup to deal with this.

Subject: powerpc/85xx: TQM85xx: correct address of LM75 I2C device nodes

Commit 0f73a449a649acfca91404a98a35353a618b9555 added I2C device nodes
for the LM75 thermal sensor on the TQM85xx modules, unfortunately with
the wrong I2C address. The LM75s are located at address 0x48.

Enable highmem support for the TQM8548-AG modules and NAND support for
the TQM8548-BE modules. Furthermore disable USB, Wireless and IDE support
because it's not available on the STK85xx starter kit.

Subject: HID: hidraw -- fix missing unlocks in unlocked_ioctl

There were 2 places that returned directly instead of releasing their
locks.  I sent a fix for this file earlier but ended up missing these
spots.  I think what happened is that I have improved my checker script
since then...  Or maybe I just screwed up.

Subject: ocfs2: Reserve 1 more cluster in expanding_inline_dir for indexed

In ocfs2_expand_inline_dir, we calculate whether we need 1 extra
cluster if we can't store the dx inline the root and save it in
dx_alloc. So add it when we call ocfs2_reserve_clusters.

Subject: drm/i915: Implement batch and ring buffer dumping

We create a debugfs node (i915_ringbuffer_data) to expose a hex dump
of the ring buffer itself.  We also expose another debugfs node
(i915_ringbuffer_info) with information on the state (i.e. head, tail
addresses) of the ringbuffer.

For batchbuffer dumping, we look at the device's active_list, dumping
each object which has I915_GEM_DOMAIN_COMMAND in its read
domains. This is all exposed through the dri/i915_batchbuffers debugfs
file with a header for each object (giving the objects gtt_offset so
that it can be matched against the offset given in the
BATCH_BUFFER_START command.

Subject: drm/i915: sync hdmi detection by hdmi identifier with 2D

Currently we detect HDMI monitor by hardware detection, but if an HDMI-DVI
adapter is used to connect a DVI monitor, hardware detection will incorrectly
take monitor as HDMI. HDMI spec says any device containing IEEE registration
identifier will be treated as HDMI device.  The patch intends to detect HDMI
monitor by drm_detect_hdmi_monitor function which follows that rule.

Subject: drm/i915: Fix use of uninitialized var in 40a5f0de

i915_gem_put_relocs_to_user returned an uninitialized value which
got returned to userspace. This caused libdrm in my setup to never
get out of a do{}while() loop retrying i915_gem_execbuffer.

result was hanging X, overheating of cpu and 2-3gb of logfile-spam.

This patch adresses the issue by
 1. initializing vars in this file where necessary
 2. correcting wrongly interpreted return values of copy_[from/to]_user

Otherwise, the results of our read didn't show up when we were faulting in
the page being read into (as happened with a testcase reading into a big

Subject: drm/i915: Allow tiling of objects with bit 17 swizzling by the CPU.

Save the bit 17 state of the pages when freeing the page list, and
reswizzle them if necessary when rebinding the pages (in case they were
swapped out).  Since we have userland with expectations that the swizzle
enums let it pread and pwrite contents accurately, we can't expose a new
swizzle enum for bit 17 (which it would have to GTT map to handle), so we
handle it down in pread and pwrite by swizzling the copy when bit 17 of the
page address is set.

Subject: xen: split construction of p2m mfn tables from registration

Build the p2m_mfn_list_list early with the rest of the p2m table, but
register it later when the real shared_info structure is in place.

Subject: xen: make xen_load_gdt simpler

Remove use of multicall machinery which is unused (gdt loading
is never performance critical).  This removes the implicit use
of percpu variables, which simplifies understanding how
the percpu code's use of load_gdt interacts with this code.

Subject: xen: mask XSAVE from cpuid

Xen leaves XSAVE set in cpuid, but doesn't allow cr4.OSXSAVE
to be set.  This confuses the kernel and it ends up crashing on
an xsetbv instruction.

At boot time, try to set cr4.OSXSAVE, and mask XSAVE out of
cpuid it we can't.  This will produce a spurious error from Xen,
but allows us to support XSAVE if/when Xen does.

This also factors out the cpuid mask decisions to boot time.

Subject: xen/mmu: weaken flush_tlb_other test

Impact: fixes crashing bug

There's no particular problem with getting an empty cpu mask,
so just shortcut-return if we get one.

Avoids crash reported by Christophe Saout <christophe@saout.de>

Subject: xen: honour VCPU availability on boot

If a VM is booted with offline VCPUs then unplug them during boot. Determining
the availability of a VCPU requires access to XenStore which is not available
at the point smp_prepare_cpus() is called, therefore we bring up all VCPUS
initially and unplug the offline ones as soon as XenStore becomes available.

Due to the process and communications issues with the 2.6.30 S3C
platform merges none of the underlying arch/arm code for S3C64xx audio
support made it into mainline, rendering the drivers useless.  Disable
them in Kconfig to avoid user confusion - users patching in the required
support can always reenable this too.

Subject: [ALSA] hda_intel: fix unexpected ring buffer positions

I found two issues with ICH7-M (it should be related to other HDA chipsets
as well):

- the ring buffer position is not reset when stream restarts (after xrun) -
  solved by moving azx_stream_reset() call from open() to prepare() callback
  and reset posbuf to zero (it might be filled with hw later than position()
  callback is called)
- irq_ignore flag should be set also when ring buffer memory area is not
  changed in prepare() callback - this patch replaces irq_ignore with
  more universal check based on jiffies clock

Subject: [ALSA] pcm-midlevel: Add more strict buffer position checks based on
 jiffies

Some drivers like Intel8x0 or Intel HDA are broken for some hardware variants.
This patch adds more strict buffer position checks based on jiffies when
internal hw_ptr is updated. Enable xrun_debug to see mangling of wrong
positions.

As a side effect, the hw_ptr interrupt update routine might do slightly better
job when many interrupts are lost.

Subject: x86, CPA: Change idmap attribute before ioremap attribute setup

Change the identity mapping with the requested attribute first, before
we setup the virtual memory mapping with the new requested attribute.

This makes sure that there is no window when identity map'ed attribute
may disagree with ioremap range on the attribute type.

This also avoids doing cpa on the ioremap'ed address twice (first in
ioremap_page_range and then in ioremap_change_attr using vaddr), and
should improve ioremap performance a bit.

Subject: x86, PAT: Change order of cpa and free in set_memory_wb

To be free of aliasing due to races, set_memory_* interfaces should
follow ordering of reserving, changing memtype to UC/WC, changing
memtype back to WB followed by free.

Subject: x86, PAT: Handle faults cleanly in set_memory_ APIs

Handle faults and do proper cleanups in set_memory_*() functions. In
some cases, these functions were not doing proper free on failure paths.

With the changes to tracking memtype of RAM pages in struct page instead
of pat list, we do not need the changes in commits c5e147. This patch
reverts that change.

Subject: x86, PAT: Changing memtype to WC ensuring no WB alias

As per SDM, there should not be any aliasing of a WC with any cacheable
type across CPUs. That is if one CPU is changing the identity map
memtype to _WC, no other CPU at the time of this change should not have a
TLB for this page that carries a WB attribute. SDM suggests to make the
page not present. But for that we will have to handle any page faults
that can potentially happen due to these pages being not present.

Other way to deal with this without having any WB mapping is to change
the page first to UC and then to WC. This ensures that we meet the SDM
requirement of no cacheable alais to WC page. This also has same or
lower overhead than marking the page not present and making it present
later.

Subject: x86, PAT: Consolidate code in pat_x_mtrr_type() and reserve_memtype()

Fix pat_x_mtrr_type() to use UC_MINUS when the mtrr type return UC. This
is to be  consistent with ioremap() and ioremap_nocache() which uses
UC_MINUS.

Consolidate the code such that reserve_memtype() also uses
pat_x_mtrr_type() when the caller doesn't specify any special attribute
(non WB attribute).

Subject: x86, PAT: Remove duplicate memtype reserve in devmem mmap

/dev/mem mmap code was doing memtype reserve/free for a while now.
Recently we added memtype tracking in remap_pfn_range, and /dev/mem mmap
uses it indirectly. So, we don't need seperate tracking in /dev/mem code
any more. That means another ~100 lines of code removed :-).

Subject: sh: Plug in support for ARCH=sh64 using sh SRCARCH.

This adds in support for building with ARCH=sh64 using the sh SRCARCH.
This tidies up the randconfig generation somewhat to make sure that we
don't end up with impossible configurations, and without having to rely
on things like KCONFIG_ALLCONFIG to detect the proper CPU support subset.

Subject: ACPI: button: remove button->device pointer

We no longer need a pointer from struct acpi_button back to the
struct acpi_device.  Everywhere we used that pointer, we either
already have, or can easily get, the acpi_device pointer without
using the copy from acpi_button.  So this patch removes the
structure element.

Subject: ACPI: button: remove control method/fixed hardware distinctions

This patch removes the driver distinction between control method (CM)
and fixed hardware (FF) buttons.  We previously needed that so we
could install either a fixed event handler or a notify handler, but
the Linux/ACPI code now handles that for us, so we don't need to
worry about it.

Note that this removes the FF/CM annotation from the "info" files
in /proc.  For example,

    /proc/acpi/button/PWRF/info:
    -type:		Power Button (FF)
    +type:		Power Button

I don't think there's anything meaningful user-space can do by
knowing whether a button is a control method or a fixed hardware
button, so nobody should be looking at the FF/CM.

Subject: ACPI: Revert conflicting workaround for BIOS w/ mangled PRT entries

2f894ef9c8b36a35d80709bedca276d2fc691941
in Linux-2.6.21 worked around BIOS with mangled _PRT entries:
http://bugzilla.kernel.org/show_bug.cgi?id=6859

d0e184abc5983281ef189db2c759d65d56eb1b80
worked around the same issue via ACPICA, and shipped in 2.6.27.

Unfortunately the two workarounds conflict:
http://bugzilla.kernel.org/show_bug.cgi?id=12270

So revert the Linux specific one.

Subject: ACPI video: handle indexed _BQC correctly

In the current code, for a box with an indexed _BQC method, we
1. get the current brightness level by evaluating _BQC
2. set the value gotten in step 1 to _BCM
3. get the current brightness level again
4. set the _BQC_use_index flag if the results gotten
   in step 1 and in step 3 don't equal.

But this logic doesn't work actually, because the _BQC_use_index
is not set when acpi_video_device_lcd_set_level is invoked.
This results in a failure in step 2.
http://bugzilla.kernel.org/show_bug.cgi?id=12249#c83

Now, we set the _BQC_use_index flag after invoking _BQC for the first
time. And reevaluate the _BQC to get the correct brightness level.

Subject: Input: i8042 - introduce a tougher reset

Some touchpads don't reset right the first time (MSI Wind U-100 for
example).  This patch will retry the reset up to 5 times.

In addition, on x86, we don't fail entire i8042 initialization if
controller reset fails in hope that keyboard port will still be
functional and user will still get a working keyboard. This is
especially important on netbooks.

There are several DMI tables in the i8042 (keyboard) driver already, but
not one for the i8042.reset option.  This patch adds such an option.

Two users for this table are added as well, the MSI Wind U-100 and the LG
X110.  The MSI Wind also needs to be in the "don't trust the pnp data" for
the touchpad to work on my machine.

Subject: Input: remove unnecessary synchronize_rcu() call

There is no need to issue serialize_rcu() after adding a new handle
to the list of handles associated with the device because new events
will "see" the new handle in the list immediately. Remove it so we
can boot a little bit faster.

Subject: nilfs2: fix lockdep recursive locking warning on bmap

The bmap semaphore of DAT file can be held while a bmap of other files
is locked.  This has caused the following false detection of lockdep
check:

mount.nilfs2/4667 is trying to acquire lock:
 (&bmap->b_sem){..--}, at: [<d0c6c4b4>] nilfs_bmap_lookup_at_level+0x1a/0x74 [nilfs2]

but task is already holding lock:
 (&bmap->b_sem){..--}, at: [<d0c6c4b4>] nilfs_bmap_lookup_at_level+0x1a/0x74 [nilfs2]

This will fix the false detection by distinguishing semaphores of the
DAT and other files.

This fixes a bug of ("nilfs2: simplify handling of active state of
segments") patch.  The patch did not take account that a base index is
increased in nilfs_sufile_get_suinfo() function if requested entries
go across block boundary on sufile.

Due to this bug, the active flag sometimes appears on wrong segments
and has induced malfunction of garbage collection.

Subject: nilfs2: fix wrong accounting and duplicate brelse in
 nilfs_sufile_set_error

The nilfs_sufile_set_error() function wrongly adjusts the number of
dirty segments instead of the number of clean segments.  In addition,
the function calls brelse() twice for the same buffer head.

This fixes these bugs.

Subject: nilfs2: segment usage file cleanups

This will simplify sufile.c by sharing common code which repeatedly
appears in routines updating a segment usage entry; a wrapper function
nilfs_sufile_update() is introduced for the purpose, and counter
modifications are integrated to a new function
nilfs_sufile_mod_counter().

This is a preparation for the successive bugfix patch ("nilfs2: fix
possible mismatch of sufile counters on recovery").

Subject: nilfs2: fix possible mismatch of sufile counters on recovery

On-disk counters ndirtysegs and ncleansegs of sufile, can go wrong
after roll-forward recovery because
nilfs_prepare_segment_for_recovery() function marks segments dirty
without adjusting value of these counters.

This fixes the problem by adding a function to sufile which does the
operation adjusting the counters, and by letting the recovery function
use it.

Subject: [ALSA] intel8x0: an attempt to make ac97_clock measurement more
 reliable

- use monotonic posix clock to measure time
- try to avoid reading zero from PICB (position in current buffer) register
- show also measured samples
- when clock is near 41000 or 44100, use exactly these values
  (they appears to be reference clocks for hardware manufacturers)

Subject: [ALSA] intel8x0: do not use zero value from PICB register

It seems that the zero value from the PICB (position in current buffer)
register is not reliable. Use jiffies to correct returned value
from the ring buffer pointer callback.

Subject: fbdev: fix info->lock deadlock in fbcon_event_notify()

fb_notifier_call_chain() is called with info->lock held, i.e.  in
do_fb_ioctl() => FBIOPUT_VSCREENINFO => fb_set_var() and the some
notifier callbacks, like fbcon_event_notify(), try to re-acquire
info->lock again.

Remove the lock/unlock_fb_info() in all the framebuffer notifier
callbacks' and be sure to always call fb_notifier_call_chain() with
info->lock held.

Subject: fbdev: fix color component field length documentation

The documentation about the meaning of the color component bitfield
lengths in pseudocolor modes is inconsistent.  Fix it, so that it
indicates the correct interpretation everywhere, i.e.  that 1 << length is
the number of palette entries.

Subject: uvesafb: fix color component length for pseudocolor modes

uvesafb incorrectly sets the length of the color fields to 6 bits for
PSEUDOCOLOR modes, even though 8 bits are always used per pixel.  Fix this
by setting the length to 8.

The switch of the DAC width from the default 6 bits to 8 bits is retained
and tracked internally in the driver, but never exposed to userspace.

Subject: efifb: exit if framebuffer address is invalid

efifb will attempt to ioremap a framebuffer even if its starting address
is 0, failing and causing an ugly backtrace in the process.  Exit before
probing if this is the case.

Subject: hwmon: sht15 humidity sensor driver

Data sheet at:
http://www.sensirion.ch/en/pdf/product_information/Datasheet-humidity-sensor-SHT1x.pdf

These sensors communicate over a 2 wire bus running a device specific
protocol.  The complexity of the driver is mainly due to handling the
substantial delays between requesting a reading and the device pulling the
data line low to indicate that the data is available.  This is handled by
an interrupt that is disabled under all other conditions.

I wasn't terribly clear on the best way to handle this, so comments on
that aspect would be particularly welcome!

Interpretation of the temperature depends on knowing the supply voltage.
If configured in a board config as a regulator consumer this is obtained
from the regulator subsystem.  If not it should be provided in the
platform data.

I've placed this driver in the hwmon subsystem as it is definitely a
device that may be used for hardware monitoring and with it's relatively
slow response times (up to 120 millisecs to get a reading) a caching
strategy certainly seems to make sense!

Subject: hfs: fix memory leak when unmounting

When an HFS filesystem is unmounted, it leaks a 2-page bitmap.  Also,
under extreme memory pressure, it's possible that hfs_releasepage() may
use a tree pointer that has not been initialized, and if so, the release
request should just be rejected.

[akpm@linux-foundation.org: free_pages(0) is legal, remove obvious comment]

Subject: sisfb: fix color component length for pseudocolor modes

sisfb incorrectly sets the length of the color fields to 6 bits
for PSEUDOCOLOR modes, even though 8 bits are always used per pixel.
Fix this by setting the length to 8.

    signals: demultiplexing SIGTRAP signal

forgot to update the NSIGTRAP define in asm-generic/siginfo.h to the new
number of sigtrap subcodes.  Nothing in the tree seems to use it, but
presumably something in user space might.  So update it.

Subject: spi: spi_write_then_read() bugfixes

The "simplify spi_write_then_read()" patch included two regressions from
the 2.6.27 behaviors:

 - The data it wrote out during the (full duplex) read side
   of the transfer was not zeroed.

 - It fails completely on half duplex hardware, such as
   Microwire and most "3-wire" SPI variants.

So, revert that patch.  A revised version should be submitted at some
point, which can get the speedup on standard hardware (full duplex)
without breaking on less-capable half-duplex stuff.

+pages.
+
+The document attempts to provide the overall rationale behind this mechanism
+and the rationale for some of the design decisions that drove the

+===================
+THE UNEVICTABLE LRU
+===================
+
+The Unevictable LRU facility adds an additional LRU list to track unevictable
+pages and to hide these pages from vmscan.  This mechanism is based on a patch
+by Larry Woodman of Red Hat to address several scalability problems with page
 reclaim in Linux.  The problems have been observed at customer sites on large
-memory x86_64 systems.  For example, a non-numal x86_64 platform with 128GB
-of main memory will have over 32 million 4k pages in a single zone.  When a
-large fraction of these pages are not evictable for any reason [see below],
-vmscan will spend a lot of time scanning the LRU lists looking for the small
-fraction of pages that are evictable.  This can result in a situation where
-all cpus are spending 100% of their time in vmscan for hours or days on end,
-with the system completely unresponsive.
-
-The Unevictable LRU infrastructure addresses the following classes of
-unevictable pages:
-
-+ page owned by ramfs
-+ page mapped into SHM_LOCKed shared memory regions
-+ page mapped into VM_LOCKED [mlock()ed] vmas
-
-The infrastructure might be able to handle other conditions that make pages
+memory x86_64 systems.
+
+To illustrate this with an example, a non-NUMA x86_64 platform with 128GB of
+main memory will have over 32 million 4k pages in a single zone.  When a large
+fraction of these pages are not evictable for any reason [see below], vmscan
+will spend a lot of time scanning the LRU lists looking for the small fraction
+of pages that are evictable.  This can result in a situation where all CPUs are
+spending 100% of their time in vmscan for hours or days on end, with the system

+
+The unevictable list addresses the following classes of unevictable pages:
+
+ (*) Those owned by ramfs.
+
+ (*) Those mapped into SHM_LOCK'd shared memory regions.
+
+ (*) Those mapped into VM_LOCKED [mlock()ed] VMAs.
+
+The infrastructure may also be able to handle other conditions that make pages
 unevictable, either by definition or by circumstance, in the future.
 
 
-The Unevictable LRU List
+THE UNEVICTABLE PAGE LIST
+-------------------------
 
 The Unevictable LRU infrastructure consists of an additional, per-zone, LRU list
 called the "unevictable" list and an associated page flag, PG_unevictable, to
-indicate that the page is being managed on the unevictable list.  The
-PG_unevictable flag is analogous to, and mutually exclusive with, the PG_active
-flag in that it indicates on which LRU list a page resides when PG_lru is set.
-The unevictable LRU list is source configurable based on the UNEVICTABLE_LRU
-Kconfig option.

+UNEVICTABLE_LRU Kconfig option.
 
 The Unevictable LRU infrastructure maintains unevictable pages on an additional
 LRU list for a few reasons:
 
-1) We get to "treat unevictable pages just like we treat other pages in the
-   system, which means we get to use the same code to manipulate them, the
-   same code to isolate them (for migrate, etc.), the same code to keep track
-   of the statistics, etc..." [Rik van Riel]

+     same code to isolate them (for migrate, etc.), the same code to keep track
+     of the statistics, etc..." [Rik van Riel]
+
+ (2) We want to be able to migrate unevictable pages between nodes for memory
+     defragmentation, workload management and memory hotplug.  The linux kernel
+     can only migrate pages that it can successfully isolate from the LRU
+     lists.  If we were to maintain pages elsewhere than on an LRU-like list,
+     where they can be found by isolate_lru_page(), we would prevent their
+     migration, unless we reworked migration code to find the unevictable pages
+     itself.

+The unevictable list does not use the LRU pagevec mechanism. Rather,
+unevictable pages are placed directly on the page's zone's unevictable list
+under the zone lru_lock.  This allows us to prevent the stranding of pages on
+the unevictable list when one task has the page isolated from the LRU and other
+tasks are changing the "evictability" state of the page.

+MEMORY CONTROL GROUP INTERACTION
+--------------------------------
 
-Unevictable LRU and Memory Controller Interaction
+The unevictable LRU facility interacts with the memory control group [aka
+memory controller; see Documentation/cgroups/memory.txt] by extending the
+lru_list enum.
+
+The memory controller data structure automatically gets a per-zone unevictable
+list as a result of the "arrayification" of the per-zone LRU lists (one per
+lru_list enum element).  The memory controller tracks the movement of pages to
+and from the unevictable list.
 
-The memory controller data structure automatically gets a per zone unevictable
-lru list as a result of the "arrayification" of the per-zone LRU lists.  The
-memory controller tracks the movement of pages to and from the unevictable list.
 When a memory control group comes under memory pressure, the controller will
 not attempt to reclaim pages on the unevictable list.  This has a couple of
-effects.  Because the pages are "hidden" from reclaim on the unevictable list,
-the reclaim process can be more efficient, dealing only with pages that have
-a chance of being reclaimed.  On the other hand, if too many of the pages
-charged to the control group are unevictable, the evictable portion of the
-working set of the tasks in the control group may not fit into the available
-memory.  This can cause the control group to thrash or to oom-kill tasks.
-
-
-Unevictable LRU:  Detecting Unevictable Pages
-
-The function page_evictable(page, vma) in vmscan.c determines whether a
-page is evictable or not.  For ramfs pages and pages in SHM_LOCKed regions,
-page_evictable() tests a new address space flag, AS_UNEVICTABLE, in the page's
-address space using a wrapper function.  Wrapper functions are used to set,
-clear and test the flag to reduce the requirement for #ifdef's throughout the
-source code.  AS_UNEVICTABLE is set on ramfs inode/mapping when it is created.
-This flag remains for the life of the inode.
-
-For shared memory regions, AS_UNEVICTABLE is set when an application
-successfully SHM_LOCKs the region and is removed when the region is
-SHM_UNLOCKed.  Note that shmctl(SHM_LOCK, ...) does not populate the page
-tables for the region as does, for example, mlock().   So, we make no special
-effort to push any pages in the SHM_LOCKed region to the unevictable list.
-Vmscan will do this when/if it encounters the pages during reclaim.  On
-SHM_UNLOCK, shmctl() scans the pages in the region and "rescues" them from the
-unevictable list if no other condition keeps them unevictable.  If a SHM_LOCKed
-region is destroyed, the pages are also "rescued" from the unevictable list in
-the process of freeing them.
-
-page_evictable() detects mlock()ed pages by testing an additional page flag,
-PG_mlocked via the PageMlocked() wrapper.  If the page is NOT mlocked, and a
-non-NULL vma is supplied, page_evictable() will check whether the vma is

+
+ (1) Because the pages are "hidden" from reclaim on the unevictable list, the
+     reclaim process can be more efficient, dealing only with pages that have a
+     chance of being reclaimed.
+
+ (2) On the other hand, if too many of the pages charged to the control group
+     are unevictable, the evictable portion of the working set of the tasks in
+     the control group may not fit into the available memory.  This can cause
+     the control group to thrash or to OOM-kill tasks.
+
+
+MARKING ADDRESS SPACES UNEVICTABLE
+----------------------------------
+
+For facilities such as ramfs none of the pages attached to the address space
+may be evicted.  To prevent eviction of any such pages, the AS_UNEVICTABLE
+address space flag is provided, and this can be manipulated by a filesystem
+using a number of wrapper functions:
+
+ (*) void mapping_set_unevictable(struct address_space *mapping);
+
+	Mark the address space as being completely unevictable.
+
+ (*) void mapping_clear_unevictable(struct address_space *mapping);
+
+	Mark the address space as being evictable.
+
+ (*) int mapping_unevictable(struct address_space *mapping);
+
+	Query the address space, and return true if it is completely
+	unevictable.
+
+These are currently used in two places in the kernel:
+
+ (1) By ramfs to mark the address spaces of its inodes when they are created,
+     and this mark remains for the life of the inode.
+
+ (2) By SYSV SHM to mark SHM_LOCK'd address spaces until SHM_UNLOCK is called.
+
+     Note that SHM_LOCK is not required to page in the locked pages if they're
+     swapped out; the application must touch the pages manually if it wants to
+     ensure they're in memory.
+
+
+DETECTING UNEVICTABLE PAGES
+---------------------------
+
+The function page_evictable() in vmscan.c determines whether a page is
+evictable or not using the query function outlined above [see section "Marking
+address spaces unevictable"] to check the AS_UNEVICTABLE flag.
+
+For address spaces that are so marked after being populated (as SHM regions
+might be), the lock action (eg: SHM_LOCK) can be lazy, and need not populate
+the page tables for the region as does, for example, mlock(), nor need it make
+any special effort to push any pages in the SHM_LOCK'd area to the unevictable
+list.  Instead, vmscan will do this if and when it encounters the pages during
+a reclamation scan.
+
+On an unlock action (such as SHM_UNLOCK), the unlocker (eg: shmctl()) must scan
+the pages in the region and "rescue" them from the unevictable list if no other
+condition is keeping them unevictable.  If an unevictable region is destroyed,
+the pages are also "rescued" from the unevictable list in the process of
+freeing them.
+
+page_evictable() also checks for mlocked pages by testing an additional page
+flag, PG_mlocked (as wrapped by PageMlocked()).  If the page is NOT mlocked,
+and a non-NULL VMA is supplied, page_evictable() will check whether the VMA is
 VM_LOCKED via is_mlocked_vma().  is_mlocked_vma() will SetPageMlocked() and
 update the appropriate statistics if the vma is VM_LOCKED.  This method allows
 efficient "culling" of pages in the fault path that are being faulted in to
-VM_LOCKED vmas.
+VM_LOCKED VMAs.
 
 
-Unevictable Pages and Vmscan [shrink_*_list()]
+VMSCAN'S HANDLING OF UNEVICTABLE PAGES
+--------------------------------------
 
 If unevictable pages are culled in the fault path, or moved to the unevictable
-list at mlock() or mmap() time, vmscan will never encounter the pages until
-they have become evictable again, for example, via munlock() and have been
-"rescued" from the unevictable list.  However, there may be situations where we
-decide, for the sake of expediency, to leave a unevictable page on one of the
-regular active/inactive LRU lists for vmscan to deal with.  Vmscan checks for
-such pages in all of the shrink_{active|inactive|page}_list() functions and
-will "cull" such pages that it encounters--that is, it diverts those pages to
-the unevictable list for the zone being scanned.
-
-There may be situations where a page is mapped into a VM_LOCKED vma, but the
-page is not marked as PageMlocked.  Such pages will make it all the way to
+list at mlock() or mmap() time, vmscan will not encounter the pages until they
+have become evictable again (via munlock() for example) and have been "rescued"
+from the unevictable list.  However, there may be situations where we decide,
+for the sake of expediency, to leave a unevictable page on one of the regular

+unevictable list for the zone being scanned.
+
+There may be situations where a page is mapped into a VM_LOCKED VMA, but the
+page is not marked as PG_mlocked.  Such pages will make it all the way to
 shrink_page_list() where they will be detected when vmscan walks the reverse

-will cull the page at that point.
+map in try_to_unmap().  If try_to_unmap() returns SWAP_MLOCK,
+shrink_page_list() will cull the page at that point.
 
-To "cull" an unevictable page, vmscan simply puts the page back on the lru
-list using putback_lru_page()--the inverse operation to isolate_lru_page()--
-after dropping the page lock.  Because the condition which makes the page
-unevictable may change once the page is unlocked, putback_lru_page() will
-recheck the unevictable state of a page that it places on the unevictable lru
-list.  If the page has become unevictable, putback_lru_page() removes it from
-the list and retries, including the page_unevictable() test.  Because such a
-race is a rare event and movement of pages onto the unevictable list should be
-rare, these extra evictabilty checks should not occur in the majority of calls
-to putback_lru_page().

-Mlocked Page:  Prior Work
+=============
+MLOCKED PAGES
+=============
 
-The "Unevictable Mlocked Pages" infrastructure is based on work originally
+The unevictable page list is also useful for mlock(), in addition to ramfs and
+SYSV SHM.  Note that mlock() is only available in CONFIG_MMU=y situations; in
+NOMMU situations, all mappings are effectively mlocked.
+
+
+HISTORY
+-------
+
+The "Unevictable mlocked Pages" infrastructure is based on work originally
 posted by Nick Piggin in an RFC patch entitled "mm: mlocked pages off LRU".
-Nick posted his patch as an alternative to a patch posted by Christoph
-Lameter to achieve the same objective--hiding mlocked pages from vmscan.
-In Nick's patch, he used one of the struct page lru list link fields as a count
-of VM_LOCKED vmas that map the page.  This use of the link field for a count
-prevented the management of the pages on an LRU list.  Thus, mlocked pages were
-not migratable as isolate_lru_page() could not find them and the lru list link
-field was not available to the migration subsystem.  Nick resolved this by
-putting mlocked pages back on the lru list before attempting to isolate them,
-thus abandoning the count of VM_LOCKED vmas.  When Nick's patch was integrated
-with the Unevictable LRU work, the count was replaced by walking the reverse
-map to determine whether any VM_LOCKED vmas mapped the page.  More on this
-below.
-
-
-Mlocked Pages:  Basic Management
-
-Mlocked pages--pages mapped into a VM_LOCKED vma--represent one class of
-unevictable pages.  When such a page has been "noticed" by the memory
-management subsystem, the page is marked with the PG_mlocked [PageMlocked()]
-flag.  A PageMlocked() page will be placed on the unevictable LRU list when

-Mlocked Pages:  mlock()/mlockall() System Call Handling
+Nick posted his patch as an alternative to a patch posted by Christoph Lameter
+to achieve the same objective: hiding mlocked pages from vmscan.
+
+In Nick's patch, he used one of the struct page LRU list link fields as a count
+of VM_LOCKED VMAs that map the page.  This use of the link field for a count
+prevented the management of the pages on an LRU list, and thus mlocked pages
+were not migratable as isolate_lru_page() could not find them, and the LRU list
+link field was not available to the migration subsystem.
+
+Nick resolved this by putting mlocked pages back on the lru list before
+attempting to isolate them, thus abandoning the count of VM_LOCKED VMAs.  When
+Nick's patch was integrated with the Unevictable LRU work, the count was
+replaced by walking the reverse map to determine whether any VM_LOCKED VMAs
+mapped the page.  More on this below.
+
+
+BASIC MANAGEMENT
+----------------
+
+mlocked pages - pages mapped into a VM_LOCKED VMA - are a class of unevictable
+pages.  When such a page has been "noticed" by the memory management subsystem,
+the page is marked with the PG_mlocked flag.  This can be manipulated using the
+PageMlocked() functions.
+
+A PG_mlocked page will be placed on the unevictable list when it is added to
+the LRU.  Such pages can be "noticed" by memory management in several places:
+
+ (1) in the mlock()/mlockall() system call handlers;
+
+ (2) in the mmap() system call handler when mmapping a region with the
+     MAP_LOCKED flag;
+
+ (3) mmapping a region in a task that has called mlockall() with the MCL_FUTURE
+     flag
+
+ (4) in the fault path, if mlocked pages are "culled" in the fault path,
+     and when a VM_LOCKED stack segment is expanded; or
+
+ (5) as mentioned above, in vmscan:shrink_page_list() when attempting to
+     reclaim a page in a VM_LOCKED VMA via try_to_unmap()
+
+all of which result in the VM_LOCKED flag being set for the VMA if it doesn't
+already have it set.
+
+mlocked pages become unlocked and rescued from the unevictable list when:
+
+ (1) mapped in a range unlocked via the munlock()/munlockall() system calls;
+
+ (2) munmap()'d out of the last VM_LOCKED VMA that maps the page, including
+     unmapping at task exit;
+
+ (3) when the page is truncated from the last VM_LOCKED VMA of an mmapped file;
+     or
+
+ (4) before a page is COW'd in a VM_LOCKED VMA.
+
+
+mlock()/mlockall() SYSTEM CALL HANDLING
+---------------------------------------
 
 Both [do_]mlock() and [do_]mlockall() system call handlers call mlock_fixup()
-for each vma in the range specified by the call.  In the case of mlockall(),
+for each VMA in the range specified by the call.  In the case of mlockall(),
 this is the entire active address space of the task.  Note that mlock_fixup()
-is used for both mlock()ing and munlock()ing a range of memory.  A call to
-mlock() an already VM_LOCKED vma, or to munlock() a vma that is not VM_LOCKED
-is treated as a no-op--mlock_fixup() simply returns.

-vma has been merged or split or neither, mlock_fixup() will call
-__mlock_vma_pages_range() to fault in the pages via get_user_pages() and
-to mark the pages as mlocked via mlock_vma_page().
-
-Note that the vma being mlocked might be mapped with PROT_NONE.  In this case,

 Also note that a page returned by get_user_pages() could be truncated or

-this, __mlock_vma_pages_range() tests the page_mapping after acquiring

-
-Mlocked Pages:  Downgrading the Mmap Semaphore.
-
-mlock_fixup() must be called with the mmap semaphore held for write, because
-it may have to merge or split vmas.  However, mlocking a large region of
-memory can take a long time--especially if vmscan must reclaim pages to
-satisfy the regions requirements.  Faulting in a large region with the mmap
-semaphore held for write can hold off other faults on the address space, in
-the case of a multi-threaded task.  It can also hold off scans of the task's
-address space via /proc.  While testing under heavy load, it was observed that
-the ps(1) command could be held off for many minutes while a large segment was
-mlock()ed down.
-
-To address this issue, and to make the system more responsive during mlock()ing
-of large segments, mlock_fixup() downgrades the mmap semaphore to read mode
-during the call to __mlock_vma_pages_range().  This works fine.  However, the
-callers of mlock_fixup() expect the semaphore to be returned in write mode.
-So, mlock_fixup() "upgrades" the semphore to write mode.  Linux does not
-support an atomic upgrade_sem() call, so mlock_fixup() must drop the semaphore
-and reacquire it in write mode.  In a multi-threaded task, it is possible for
-the task memory map to change while the semaphore is dropped.  Therefore,
-mlock_fixup() looks up the vma at the range start address after reacquiring
-the semaphore in write mode and verifies that it still covers the original
-range.  If not, mlock_fixup() returns an error [-EAGAIN].  All callers of
-mlock_fixup() have been changed to deal with this new error condition.
-
-Note:  when munlocking a region, all of the pages should already be resident--
-unless we have racing threads mlocking() and munlocking() regions.  So,
-unlocking should not have to wait for page allocations nor faults  of any kind.
-Therefore mlock_fixup() does not downgrade the semaphore for munlock().

-Mlocked Pages:  munlock()/munlockall() System Call Handling

-The munlock() and munlockall() system calls are handled by the same functions--
-do_mlock[all]()--as the mlock() and mlockall() system calls with the unlock
-vs lock operation indicated by an argument.  So, these system calls are also
-handled by mlock_fixup().  Again, if called for an already munlock()ed vma,
-mlock_fixup() simply returns.  Because of the vma filtering discussed above,

+As a result, vmscan/shrink_page_list() might encounter such a page as described

-Unmapping of a mapped file page works the same, except that the scan visits
-all vmas that maps the page's index/page offset in the page's mapping's

-
-If a page's mapping contains a non-empty non-linear mapping vma list, then
-try_to_un{map|lock}() must also visit each vma in that list to determine
-whether the page is mapped in a VM_LOCKED vma.  Again, the scan must visit
-all vmas in the non-linear list to ensure that the pages is not/should not be
-mlocked.  If a VM_LOCKED vma is found in the list, the scan could terminate.
-However, there is no easy way to determine whether the page is actually mapped
-in a given vma--either for unmapping or testing whether the VM_LOCKED vma

-
-So, try_to_unmap_file() handles non-linear mappings by scanning a certain
-number of pages--a "cluster"--in each non-linear vma associated with the page's

-to unmap the page we're trying to unmap, try_to_unmap() will notice this on

-advantage of the cluster scan in try_to_unmap_cluster() as follows:
-
-For each non-linear vma, try_to_unmap_cluster() attempts to acquire the mmap
-semaphore of the associated mm_struct for read without blocking.  If this

-retain the mmap semaphore for the scan; otherwise it drops it here.  Then,
-for each page in the cluster, if we're holding the mmap semaphore for a locked
-vma, try_to_unmap_cluster() calls mlock_vma_page() to mlock the page.  This
-call is a no-op if the page is already locked, but will mlock any pages in

+try_to_munlock() REVERSE MAP SCAN
+---------------------------------
+
+ [!] TODO/FIXME: a better name might be page_mlocked() - analogous to the
+     page_referenced() reverse map walker.
+
+When munlock_vma_page() [see section "munlock()/munlockall() System Call
+Handling" above] tries to munlock a page, it needs to determine whether or not
+the page is mapped by any VM_LOCKED VMA without actually attempting to unmap
+all PTEs from the page.  For this purpose, the unevictable/mlock infrastructure
+introduced a variant of try_to_unmap() called try_to_munlock().
 
 try_to_munlock() calls the same functions as try_to_unmap() for anonymous and
 mapped file pages with an additional argument specifing unlock versus unmap
 processing.  Again, these functions walk the respective reverse maps looking
-for VM_LOCKED vmas.  When such a vma is found for anonymous pages and file
+for VM_LOCKED VMAs.  When such a VMA is found for anonymous pages and file
 pages mapped in linear VMAs, as in the try_to_unmap() case, the functions
 attempt to acquire the associated mmap semphore, mlock the page via
 mlock_vma_page() and return SWAP_MLOCK.  This effectively undoes the
 pre-clearing of the page's PG_mlocked done by munlock_vma_page.
 
-If try_to_unmap() is unable to acquire a VM_LOCKED vma's associated mmap
-semaphore, it will return SWAP_AGAIN.  This will allow shrink_page_list()
-to recycle the page on the inactive list and hope that it has better luck
-with the page next time.
-
-For file pages mapped into non-linear vmas, the try_to_munlock() logic works
-slightly differently.  On encountering a VM_LOCKED non-linear vma that might
-map the page, try_to_munlock() returns SWAP_AGAIN without actually mlocking
-the page.  munlock_vma_page() will just leave the page unlocked and let
-vmscan deal with it--the usual fallback position.
-
-Note that try_to_munlock()'s reverse map walk must visit every vma in a pages'
-reverse map to determine that a page is NOT mapped into any VM_LOCKED vma.
-However, the scan can terminate when it encounters a VM_LOCKED vma and can
-successfully acquire the vma's mmap semphore for read and mlock the page.
-Although try_to_munlock() can be called many [very many!] times when
-munlock()ing a large region or tearing down a large address space that has been
-mlocked via mlockall(), overall this is a fairly rare event.
-
-Mlocked Page:  Page Reclaim in shrink_*_list()
-
-shrink_active_list() culls any obviously unevictable pages--i.e.,
-!page_evictable(page, NULL)--diverting these to the unevictable lru
-list.  However, shrink_active_list() only sees unevictable pages that
-made it onto the active/inactive lru lists.  Note that these pages do not
-have PageUnevictable set--otherwise, they would be on the unevictable list and
-shrink_active_list would never see them.

+PAGE RECLAIM IN shrink_*_list()
+-------------------------------
+
+shrink_active_list() culls any obviously unevictable pages - i.e.
+!page_evictable(page, NULL) - diverting these to the unevictable list.
+However, shrink_active_list() only sees unevictable pages that made it onto the
+active/inactive lru lists.  Note that these pages do not have PageUnevictable
+set - otherwise they would be on the unevictable list and shrink_active_list
+would never see them.
 
 Some examples of these unevictable pages on the LRU lists are:
 
-1) ramfs pages that have been placed on the lru lists when first allocated.
+ (1) ramfs pages that have been placed on the LRU lists when first allocated.
+
+ (2) SHM_LOCK'd shared memory pages.  shmctl(SHM_LOCK) does not attempt to

+     when an application accesses the page the first time after SHM_LOCK'ing
+     the segment.

+ (4) Pages mapped into multiple VM_LOCKED VMAs, but try_to_munlock() couldn't

-shrink_inactive_list() also culls any unevictable pages that it finds on

Subject: ptrace: fix exit_ptrace() vs ptrace_traceme() race

Pointed out by Roland.  The bug was recently introduced by me in
"forget_original_parent: split out the un-ptrace part", commit
39c626ae47c469abdfd30c6e42eff884931380d6.

Since that patch we have a window after exit_ptrace() drops tasklist and
before forget_original_parent() takes it again.  In this window the child
can do ptrace(PTRACE_TRACEME) and nobody can untrace this child after
that.

Change ptrace_traceme() to not attach to the exiting ->real_parent.  We
don't report the error in this case, we pretend we attach right before
->real_parent calls exit_ptrace() which should untrace us anyway.

Subject: initramfs: fix initramfs to work with hardlinked init

Change cb6ff208076b5f434db1b8c983429269d719cef5 ("NOMMU: Support XIP on
initramfs") seems to have broken booting from initramfs with /sbin/init
being a hardlink.

It seems like the logic required for XIP on nommu, i.e.  ftruncate to
reported cpio header file size (body_len) is broken for hardlinks, which
have a reported size of 0, and the truncate thus nukes the contents of the
file (in my case busybox), making boot impossible and ending with runaway
loop modprobe binfmt-0000 - and of course 0000 is not a valid binary
format.

My fix is to only call ftruncate if size is non-zero which fixes things
for me, but I'm not certain whether this will break XIP for those files on
nommu systems, although I would guess not.

While better than get_user_pages(), the usage of gupf(), especially the
return values and the fact that it can potentially only partially pin the
range, warranted some documentation.

+
+Basically, the new setup is:
+
+ - we have "real address spaces" and "anonymous address spaces". The
+   difference is that an anonymous address space doesn't care about the
+   user-level page tables at all, so when we do a context switch into an
+   anonymous address space we just leave the previous address space
+   active.
+
+   The obvious use for a "anonymous address space" is any thread that
+   doesn't need any user mappings - all kernel threads basically fall into
+   this category, but even "real" threads can temporarily say that for
+   some amount of time they are not going to be interested in user space,
+   and that the scheduler might as well try to avoid wasting time on
+   switching the VM state around. Currently only the old-style bdflush
+   sync does that.
+
+ - "tsk->mm" points to the "real address space". For an anonymous process,
+   tsk->mm will be NULL, for the logical reason that an anonymous process
+   really doesn't _have_ a real address space at all.
+
+ - however, we obviously need to keep track of which address space we
+   "stole" for such an anonymous user. For that, we have "tsk->active_mm",
+   which shows what the currently active address space is.
+
+   The rule is that for a process with a real address space (ie tsk->mm is
+   non-NULL) the active_mm obviously always has to be the same as the real
+   one.
+
+   For a anonymous process, tsk->mm == NULL, and tsk->active_mm is the
+   "borrowed" mm while the anonymous process is running. When the
+   anonymous process gets scheduled away, the borrowed address space is
+   returned and cleared.
+
+To support all that, the "struct mm_struct" now has two counters: a
+"mm_users" counter that is how many "real address space users" there are,
+and a "mm_count" counter that is the number of "lazy" users (ie anonymous
+users) plus one if there are any real users.
+
+Usually there is at least one real user, but it could be that the real
+user exited on another CPU while a lazy user was still active, so you do
+actually get cases where you have a address space that is _only_ used by
+lazy users. That is often a short-lived state, because once that thread
+gets scheduled away in favour of a real thread, the "zombie" mm gets
+released because "mm_users" becomes zero.
+
+Also, a new rule is that _nobody_ ever has "init_mm" as a real MM any
+more. "init_mm" should be considered just a "lazy context when no other
+context is available", and in fact it is mainly used just at bootup when
+no real VM has yet been created. So code that used to check
+
+	if (current->mm == &init_mm)
+
+should generally just do
+
+	if (!current->mm)
+
+instead (which makes more sense anyway - the test is basically one of "do
+we have a user context", and is generally done by the page fault handler
+and things like that).
+
+Anyway, I put a pre-patch-2.3.13-1 on ftp.kernel.org just a moment ago,
+because it slightly changes the interfaces to accomodate the alpha (who
+would have thought it, but the alpha actually ends up having one of the
+ugliest context switch codes - unlike the other architectures where the MM
+and register state is separate, the alpha PALcode joins the two, and you
+need to switch both together).

Subject: shmem: fix division by zero

Fix a division by zero which we have in shmem_truncate_range() and
shmem_unuse_inode() when using big PAGE_SIZE values (e.g.  256kB on
ppc44x).

With 256kB PAGE_SIZE, the ENTRIES_PER_PAGEPAGE constant becomes too large
(0x1.0000.0000) on a 32-bit kernel, so this patch just changes its type
from 'unsigned long' to 'unsigned long long'.

Hugh: reverted its unsigned long longs in shmem_truncate_range() and
shmem_getpage(): the pagecache index cannot be more than an unsigned long,
so the divisions by zero occurred in unreached code.  It's a pity we need
any ULL arithmetic here, but I found no pretty way to avoid it.

Subject: shmem: respect MAX_LFS_FILESIZE

SHMEM_MAX_BYTES was derived from the maximum size of its triple-indirect
swap vector, forgetting to take the MAX_LFS_FILESIZE limit into account.
Never mind 256kB pages, even 8kB pages on 32-bit kernels allowed files to
grow slightly bigger than that supposed maximum.

Fix this by using the min of both (at build time not run time).  And it
happens that this calculation is good as far as 8MB pages on 32-bit or
16MB pages on 64-bit: though SHMSWP_MAX_INDEX gets truncated before that,
it's truncated to such large numbers that we don't need to care.

Subject: ext2: fix data corruption for racing writes

If two writers allocating blocks to file race with each other (e.g.
because writepages races with ordinary write or two writepages race with
each other), ext2_getblock() can be called on the same inode in parallel.
Before we are going to allocate new blocks, we have to recheck the block
chain we have obtained so far without holding truncate_mutex.  Otherwise
we could overwrite the indirect block pointer set by the other writer
leading to data loss.

The below test program by Ying is able to reproduce the data loss with ext2
on in BRD in a few minutes if the machine is under memory pressure:

long kMemSize  = 50 << 20;
int kPageSize = 4096;

int main(int argc, char **argv) {
	int status;
	int count = 0;
	int i;
	char *fname = "/mnt/test.mmap";
	char *mem;
	unlink(fname);
	int fd = open(fname, O_CREAT | O_EXCL | O_RDWR, 0600);
	status = ftruncate(fd, kMemSize);
	mem = mmap(0, kMemSize, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);
	// Fill the memory with 1s.
	memset(mem, 1, kMemSize);
	sleep(2);
	for (i = 0; i < kMemSize; i++) {
		int byte_good = mem[i] != 0;
		if (!byte_good && ((i % kPageSize) == 0)) {
			//printf("%d ", i / kPageSize);
			count++;
		}
	}
	munmap(mem, kMemSize);
	close(fd);
	unlink(fname);

	if (count > 0) {
		printf("Running %d bad page\n", count);
		return 1;
	}
	return 0;
}

Subject: Replace all DMA_nBIT_MASK macro with DMA_BIT_MASK(n)

This is the second go through of the old DMA_nBIT_MASK macro,and there're not
so many of them left,so I put them into one patch.I hope this is the last round.
After this the definition of the old DMA_nBIT_MASK macro could be removed.

The description about various statistics from memory.stat is not accurate
and confusing at times.

Correct this along with a few other minor cleanups.

Subject: sgi-xpc: prevent false heartbeat failures

The heartbeat timeout functionality in sgi-xpc is currently not trained to
the connection time.  If a connection is made and the code is in the last
polling window prior to doing a timeout, the next polling window will see
the heartbeat as unchanged and initiate a no-heartbeat disconnect.

Subject: sgi-xpc: implement opencomplete messaging

sgi-xpc has a window of failure where an open message can be sent and a
subsequent data message can get lost.  We have added a new message
(opencomplete) which closes that window.

Subject: edac: fix local pci_write_bits32

Fix the edac local pci_write_bits32 to properly note the 'escape' mask if
all ones in a 32-bit word.

Currently no consumer of this function uses that mask, so there is no
danger to existing code.

Subject: edac: use to_delayed_work()

The edac-core driver includes code which assumes that the work_struct
which is included in every delayed_work is the first member of that
structure.  This is currently the case but might change in the future, so
use to_delayed_work() instead, which doesn't make such an assumption.

linux-2.6.30-rc1 has the to_delayed_work() function that will allow this
patch to work

Subject: sh: sh7786: modify usb setup timeout judgment bug.

This corrects a race with the PHY RST bit not being set properly if the
PLL status changes right before timeout. This resulted in it potentially
failing even if the device came up in time.

Special thanks to Mr. Juha Leppanen and Iwamatsu-san for reporting this
out and reviewing it.

+--- What is TOMOYO? ---
+
+TOMOYO is a name-based MAC extension (LSM module) for the Linux kernel.
+
+LiveCD-based tutorials are available at
+http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/ubuntu8.04-live/
+http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/centos5-live/ .
+Though these tutorials use non-LSM version of TOMOYO, they are useful for you
+to know what TOMOYO is.
+
+--- How to enable TOMOYO? ---
+
+Build the kernel with CONFIG_SECURITY_TOMOYO=y and pass "security=tomoyo" on
+kernel's command line.
+
+Please see http://tomoyo.sourceforge.jp/en/2.2.x/ for details.
+
+--- Where is documentation? ---
+
+User <-> Kernel interface documentation is available at
+http://tomoyo.sourceforge.jp/en/2.2.x/policy-reference.html .
+
+Materials we prepared for seminars and symposiums are available at
+http://sourceforge.jp/projects/tomoyo/docs/?category_id=532&language_id=1 .
+Below lists are chosen from three aspects.
+
+What is TOMOYO?
+  TOMOYO Linux Overview
+    http://sourceforge.jp/projects/tomoyo/docs/lca2009-takeda.pdf
+  TOMOYO Linux: pragmatic and manageable security for Linux
+    http://sourceforge.jp/projects/tomoyo/docs/freedomhectaipei-tomoyo.pdf
+  TOMOYO Linux: A Practical Method to Understand and Protect Your Own Linux Box
+    http://sourceforge.jp/projects/tomoyo/docs/PacSec2007-en-no-demo.pdf
+
+What can TOMOYO do?
+  Deep inside TOMOYO Linux
+    http://sourceforge.jp/projects/tomoyo/docs/lca2009-kumaneko.pdf
+  The role of "pathname based access control" in security.
+    http://sourceforge.jp/projects/tomoyo/docs/lfj2008-bof.pdf
+
+History of TOMOYO?
+  Realities of Mainlining
+    http://sourceforge.jp/projects/tomoyo/docs/lfj2008.pdf
+
+--- What is future plan? ---
+
+We believe that inode based security and name based security are complementary
+and both should be used together. But unfortunately, so far, we cannot enable
+multiple LSM modules at the same time. We feel sorry that you have to give up
+SELinux/SMACK/AppArmor etc. when you want to use TOMOYO.
+
+We hope that LSM becomes stackable in future. Meanwhile, you can use non-LSM
+version of TOMOYO, available at http://tomoyo.sourceforge.jp/en/1.6.x/ .
+LSM version of TOMOYO is a subset of non-LSM version of TOMOYO. We are planning
+to port non-LSM version's functionalities to LSM versions.

Subject: x86: pci-swiotlb.c swiotlb_dma_ops should be static

Impact: reduce kernel size a bit, address sparse warning

Addresses the problem pointed out by this sparse warning:

  arch/x86/kernel/pci-swiotlb.c:53:20: warning: symbol 'swiotlb_dma_ops' was not declared. Should it be static?

For x86: swiotlb_dma_ops can be static, because it's not used outside
of pci-swiotlb.c

Subject: Fix quilt merge error in acpi-cpufreq.c

We ended up incorrectly using '&cur' instead of '&readin' in the
work_on_cpu() -> smp_call_function_single() transformation in commit
01599fca6758d2cd133e78f87426fc851c9ea725 ("cpufreq: use
smp_call_function_[single|many]() in acpi-cpufreq.c").

Andrew explains:
 "OK, the acpi tree went and had conflicting changes merged into it after
  I'd written the patch and it appears that I incorrectly reverted part
  of 18b2646fe3babeb40b34a0c1751e0bf5adfdc64c while fixing the resulting
  rejects.

  Switching it to `readin' looks correct."

Subject: md: allow setting newly added device to 'in_sync' via sysfs.

When adding devices to an active array via sysfs, there is currently
no way to mark a device as 'in-sync' which is useful when
incrementally assembling an array.

So add that option.

Subject: md: improve usefulness and accuracy of sysfs file md/sync_completed.

The sync_completed file reports how much of a resync (or recovery or
reshape) has been completed.
However due to the possibility of out-of-order completion of writes,
it is not certain to be accurate.

We have an internal value - mddev->curr_resync_completed - which is an
accurate value (though it might not always be quite so uptodate).

So:
 - make curr_resync_completed be uptodate a little more often,
   particularly when raid5 reshape updates status in the metadata
 - report curr_resync_completed in the sysfs file
 - allow poll/select to report all updates to md/sync_completed.

This makes sync_completed completed usable by any external metadata
handler that wants to record this status information in its metadata.

Subject: lockdep: warn about lockdep disabling after kernel taint, fix

Impact: build fix for Sparc and s390

Stephen Rothwell reported that the Sparc build broke:

 In file included from kernel/panic.c:12:
 include/linux/debug_locks.h: In function '__debug_locks_off':
 include/linux/debug_locks.h:15: error: implicit declaration of function 'xchg'

due to:

 9eeba61: lockdep: warn about lockdep disabling after kernel taint

There is some inconsistency between architectures about where exactly
xchg() is defined.

The traditional place is in system.h but the more logical point for it
is in atomic.h - where most architectures (especially new ones) have
it defined. These architecture also still offer it via system.h.

Some, such as Sparc or s390 only have it in asm/system.h and not available
via asm/atomic.h at all.

Use the widest set of headers in debug_locks.h and also include asm/system.h.

Subject: rcu: Make hierarchical RCU less IPI-happy

This patch fixes a hierarchical-RCU performance bug located by Anton
Blanchard.  The problem stems from a misguided attempt to provide a
work-around for jiffies-counter failure.  This work-around uses a per-CPU
n_rcu_pending counter, which is incremented on each call to rcu_pending(),
which in turn is called from each scheduling-clock interrupt.  Each CPU
then treats this counter as a surrogate for the jiffies counter, so
that if the jiffies counter fails to advance, the per-CPU n_rcu_pending
counter will cause RCU to invoke force_quiescent_state(), which in turn
will (among other things) send resched IPIs to CPUs that have thus far
failed to pass through an RCU quiescent state.

Unfortunately, each CPU resets only its own counter after sending a
batch of IPIs.  This means that the other CPUs will also (needlessly)
send -another- round of IPIs, for a full N-squared set of IPIs in the
worst case every three scheduler-clock ticks until the grace period
finally ends.  It is not reasonable for a given CPU to reset each and
every n_rcu_pending for all the other CPUs, so this patch instead simply
disables the jiffies-counter "training wheels", thus eliminating the
excessive IPIs.

Note that the jiffies-counter IPIs do not have this problem due to
the fact that the jiffies counter is global, so that the CPU sending
the IPIs can easily reset things, thus preventing the other CPUs from
sending redundant IPIs.

Note also that the n_rcu_pending counter remains, as it will continue to
be used for tracing.  It may also see use to update the jiffies counter,
should an appropriate kick-the-jiffies-counter API appear.

Subject: jbd2: use SWRITE_SYNC_PLUG when writing synchronous revoke records

The revoke records must be written using the same way as the rest of
the blocks during the commit process; that is, either marked as
synchronous writes or as asynchornous writes.

Subject: x86, irq: Remove IRQ_DISABLED check in process context IRQ move

As discussed in the thread here:

  http://marc.info/?l=linux-kernel&m=123964468521142&w=2

Eric W. Biederman observed:

Yes. The idea here was to force the MSI migration to happen in process
context. One of the patches in the series did

        disable_irq(dev->irq);
        irq_set_affinity(dev->irq, cpumask_of(dev->cpu));
        enable_irq(dev->irq);

with the above patch adding irq/manage code check for interrupt disabled
and moving the interrupt in process context.

IIRC, there was no IRQ_MOVE_PCNTXT when we were developing this HPET
code and we ended up having this ugly hack. IRQ_MOVE_PCNTXT was there
when we eventually submitted the patch upstream. But, looks like I did a
blind rebasing instead of using IRQ_MOVE_PCNTXT in hpet MSI code.

Below patch fixes this. i.e., revert commit 932775a4ab622e3c99bd59f14cc
and add PCNTXT to HPET MSI setup. Also removes copying of desc->affinity
in generic code as set_affinity routines are doing it internally.

Subject: [S390] s390: move machine flags to lowcore

Currently the storage of the machine flags is a globally exported unsigned
long long variable. By moving the storage location into the lowcore struct we
allow assembler code to check machine_flags directly even without needing a
register. Addtionally the lowcore and therefore the machine flags too will be
in cache most of the time.

Subject: [S390] extend virtual timer interface by mod_virt_timer_periodic

In case mod_virt_timer is used to add a non pending timer the timer
is always added as a one-shot timer. If mod_virt_timer is used for
periodic timers they may therfore be degraded to one-shot timers.

Add mod_virt_timer_periodic to the interface to allow safe re-programming
of the interval value.

Subject: [S390] appldata: Use new mod_virt_timer_periodic() function.

mod_virt_timer() was used to modify/add cpu timers for cpus that were
set online. This resulted in a one-shot timer for every cpu that was
newly added or previously set offline, instead of an interval timer,
which broke the appldata vtime interval setup.

To fix this, the new mod_virt_timer_periodic() function is used, which
adds interval timers instead of one-shot timers.

The QDIO ccw devices are started by ccw_device_start so no timeout
can occur for the interrupt handler. Remove the dead code.

In case of an I/O error set the device state to error and wake up
a possibly running qdio_shutdown waiter.

Subject: [S390] dasd: Use the new async framework for autoonlining.

The dasd driver can automatically online detected dasds, which
especially important for finding the root device. Currently,
it will wait for each online operation to finish individually,
which may take long if many dasds need to be onlined. When using
the new async framework, these onlining operations can run in
parallel and presence of the root device is ensured by the fact
that prepare_namespace() waits for all async threads to finish.

Subject: [S390] dasd: fix idaw boundary checking for track based ccw

A ccw command that reads or writes several records at once will
usually transfer more data then fits into one page and needs to
address memory areas using a list of indirect data address words
(idaw). All but the first of these areas must start on a 4KB or 2KB
block boundary (depending on the idaw format).
A check for this restriction was missing and has been added with
this patch.

Subject: [S390] smp: fix cpu_possible_map initialization

The cpu_possible_map by default is initialized with all ones in s390.
If the kernel paramert possible_cpus=<x> is passed the cpu_possible_map
is supposed to have x bits set.
However the current code just sets the x bits without clearing the NR_CPUS
bits that were already set. So we end up with an unchanged map that has
all bits set.
To fix this just clear the map before setting any new bits.

This broke with def6cfb70bab83c0094bc0cedd27c4eda563043e

Subject: [S390] fix idle time accounting

The steal time is calculated by subtracting the time the virtual cpu
has been running on a physical cpu from the wall clock time. To make
that work all wall time needs to be added to the steal time field first
before the virtual cpu time is subtracted.

The time between the last clock update and the load of the enabled wait
psw needs to be added to the steal_time field as well to make the sum
over all cpu accounting numbers match the wall clock.

Subject: [S390] add read_persistent_clock

Add a read_persistent_clock function that does not just return 0.
Since timekeeping_init calls the function before time_init has been
called move reset_tod_clock to early.c to make sure that the TOD
clock is running when read_persistent_clock is invoked.

Subject: [S390] boot cputime accounting

Start the cpu time accounting very early to catch the cpu time spent
for the initial kernel setup. To make the output of /proc/uptime
match the sum of all cpu accounting values of the boot cpu reset
xtime and wall_to_monotonic to sane values based on the TOD clock.
The values set by timekeeping_init are off by up to a second.

Subject: ALSA: add private_data to struct snd_jack

Added private_data and private_free fields to struct snd_jack so that
the caller can assign the data.  It'll be helpful for avoiding the
double-free of the jack instance.

Subject: ALSA: hda - Avoid call of snd_jack_report at release

Don't call snd_jack_report at release of sigmatel and conexnat codecs
which results in Oops at unloading the module.

The Oops is triggered by the power-up sequence during the free due to
the pincfg restoration.  Since the power-up sequence is involved with
the unsol handling, the jack reporting may be issued during that.
The Oops occurs with this jack reporting because the jack instances
have been already released but the codec doesn't do the proper
book-keeping.

This patch adds the book-keeping of jack instances to avoid the access
to bogus pointers.

Subject: cdc-acm: Fix long standing abuse of tty->low_latency

ACM sets the low latency flag but calls the flip buffer routines from
IRQ context which isn't permitted (and as of 2.6.29 causes a warning
hence this one was caught)

Fortunatelt ACM doesn't need to set this flag in the first place as it
only set it to work around problems in ancient (pre tty flip rewrite)
kernels.

In commit 51dcdfec6a274afc1c6fce180d582add9ff512c0 ("parport: Use the
PCI IRQ if offered") parport_pc_probe_port() gained an irqflags arg.
This isn't being supplied on powerpc.  This patch make powerpc fallback
to the old behaviour, that is using "0" for irqflags.

Fixes build failure:

Subject: x86: UV: BAU partition-relative distribution map

This patch enables each partition's BAU distribution bit map
to be partition-relative.

The distribution bitmap had been constructed assuming 0 as the base
node number.  That construct would not have allowed a total system of
greater than 256 nodes.
It also corrects an error that occurred when the first blade's nasid
was not zero.  That nasid was stored as the base node.
The base node number gets added by hardware to the node numbers implied
in the distribution bitmap, resulting in invalid target nasids.

Tested on the UV hardware simulator.

Subject: Fix lpfc_parse_bg_err()'s use of do_div()

Fix lpfc_parse_bg_err()'s use of do_div().  It should be passing a 64-bit
variable as the first parameter.  However, since it's only using a 32-bit
variable, it doesn't need to use do_div() at all, but can instead use the
division operator.

This deals with the following warnings:

    CC      drivers/scsi/lpfc/lpfc_scsi.o
  drivers/scsi/lpfc/lpfc_scsi.c: In function 'lpfc_parse_bg_err':

Subject: x86 microcode: revert some work_on_cpu

Revert part of af5c820a3169e81af869c113e18ec7588836cd50 ("x86: cpumask:
use work_on_cpu in arch/x86/kernel/microcode_core.c")

That change is causing only one Intel CPU's microcode to be updated e.g.
microcode: CPU3 updated from revision 0x9 to 0x17, date = 2005-04-22
where before it announced that also for CPU0 and CPU1 and CPU2.

We cannot use work_on_cpu() in the CONFIG_MICROCODE_OLD_INTERFACE code,
because Intel's request_microcode_user() involves a copy_from_user() from
/sbin/microcode_ctl, which therefore needs to be on that CPU at the time.

one supported by the generic AC97 driver only which provides callbacks
to allow board-specific configuration at stream startup and teardown,
and another for pxa2xx-ac97-lib which allows configuration of the reset
GPIO for PXA2xx CPUs.

Obviously this won't actually work when using the generic AC97 driver
since the drivers will attempt to parse the platform data in both
formats. Fix this by merging the two structures.

Subject: [ARM] pxa/mioa701: use GPIO95 as AC97 reset line

MioA701 board's GPIO95 is the AC97 line. The other GPIO113
is not connected to the sound chip, but to the GSM chip as a
wakeup line.

It happens that when the pxa2xx_ac97 driver reconfigures the
gpio as an "out gpio" for AC97 reset (bug workaround), it
hangs the GSM chip.

As AC97 platform data now enables to specify the AC97 reset
line, use it.

Subject: powerpc/pseries: Set error_state to pci_channel_io_normal in
 eeh_report_reset()

While adding native EEH support to Emulex and Qlogic drivers, it was
discovered that dev->error_state was set to pci_io_channel_normal too
late in the recovery process. These drivers rely on error_state to
determine if they can access the device in their slot_reset callback,
thus error_state needs to be set to pci_io_channel_normal in
eeh_report_reset(). Below is a detailed explanation (courtesy of Richard
Lary) as to why this is necessary.

Background:
PCI MMIO or DMA accesses to a frozen slot generate additional EEH
errors. If the number of additional EEH errors exceeds EEH_MAX_FAILS the
adapter will be shutdown. To avoid triggering excessive EEH errors and
an undesirable adapter shutdown, some drivers use the
pci_channel_offline(dev) wrapper function to return a Boolean value
based on the value of pci_dev->error_state to determine if PCI MMIO or
DMA accesses are safe. If the wrapper returns TRUE, drivers must not
make PCI MMIO or DMA access to their hardware.

The pci_dev structure member error_state reflects one of three values,
1) pci_channel_io_normal, 2) pci_channel_io_frozen, 3)
pci_channel_io_perm_failure.  Function pci_channel_offline(dev) returns
TRUE if error_state is pci_channel_io_frozen or pci_channel_io_perm_failure.

The EEH driver sets pci_dev->error_state to pci_channel_io_frozen at the
point where the PCI slot is frozen. Currently, the EEH driver restores
dev->error_state to pci_channel_io_normal in eeh_report_resume() before
calling the driver's resume callback. However, when the EEH driver calls
the driver's slot_reset callback() from eeh_report_reset(), it
incorrectly indicates the error state is still pci_channel_io_frozen.

Waiting until eeh_report_resume() to restore dev->error_state to
pci_channel_io_normal is too late for Emulex and QLogic FC drivers and
any other drivers which are designed to use common code paths in these
two cases: i) those called after the driver's slot_reset callback() and
ii) those called after the PCI slot is frozen but before the driver's
slot_reset callback is called. Case i) all driver paths executed to
reinitialize the hardware after a reset and case ii) all code paths
executed by driver kernel threads that run asynchronous to the main
driver thread, such as interrupt handlers and worker threads to process
driver work queues.

Emulex and QLogic FC drivers are designed with common code paths which
require that pci_channel_offline(dev) reflect the true state of the
hardware. The state transitions that the hardware takes from Normal
Operations to Slot Frozen to Reset to Normal Operations are documented
in the Power Architecture™ Platform Requirements+ (PAPR+) in Table 75.
PE State Control.

PAPR defines the following 3 states:

0 -- Not reset, Not EEH stopped, MMIO load/store allowed, DMA allowed
     (Normal Operations)
1 -- Reset, Not EEH stopped, MMIO load/store disabled, DMA disabled
2 -- Not reset, EEH stopped, MMIO load/store disabled, DMA disabled
     (Slot Frozen)

An EEH error places the slot in state 2 (Frozen) and the adapter driver
is notified that an EEH error was detected. If the adapter driver
returns PCI_ERS_RESULT_NEED_RESET, the EEH driver calls
eeh_reset_device() to place the slot into state 1 (Reset) and
eeh_reset_device completes by placing the slot into State 0 (Normal
Operations). Upon return from eeh_reset_device(), the EEH driver calls
eeh_report_reset, which then calls the adapter's slot_reset callback. At
the time the adapter's slot_reset callback is called, the true state of
the hardware is Normal Operations and should be accurately reflected by
setting dev->error_state to pci_channel_io_normal.

The current implementation of EEH driver does not do so and requires
this change to correct this deficiency.

Subject: powerpc: Fix data-corrupting bug in __futex_atomic_op

Richard Henderson pointed out that the powerpc __futex_atomic_op has a
bug: it will write the wrong value if the stwcx. fails and it has to
retry the lwarx/stwcx. loop, since 'oparg' will have been overwritten
by the result from the first time around the loop.  This happens
because it uses the same register for 'oparg' (an input) as it uses
for the result.

This fixes it by using separate registers for 'oparg' and 'ret'.

It's a somewhat twisty maze of hints and behavioural modifiers, try
and clear it up a bit with some documentation.

+/*
+ * The below are the various read and write types that we support. Some of
+ * them include behavioral modifiers that send information down to the
+ * block layer and IO scheduler. Terminology:
+ *
+ *	The block layer uses device plugging to defer IO a little bit, in
+ *	the hope that we will see more IO very shortly. This increases
+ *	coalescing of adjacent IO and thus reduces the number of IOs we
+ *	have to send to the device. It also allows for better queuing,
+ *	if the IO isn't mergeable. If the caller is going to be waiting
+ *	for the IO, then he must ensure that the device is unplugged so
+ *	that the IO is dispatched to the driver.
+ *
+ *	All IO is handled async in Linux. This is fine for background
+ *	writes, but for reads or writes that someone waits for completion
+ *	on, we want to notify the block layer and IO scheduler so that they
+ *	know about it. That allows them to make better scheduling
+ *	decisions. So when the below references 'sync' and 'async', it
+ *	is referencing this priority hint.
+ *
+ * With that in mind, the available types are:
+ *
+ * READ			A normal read operation. Device will be plugged.
+ * READ_SYNC		A synchronous read. Device is not plugged, caller can
+ *			immediately wait on this read without caring about
+ *			unplugging.
+ * READA		Used for read-ahead operations. Lower priority, and the
+ *			 block layer could (in theory) choose to ignore this
+ *			request if it runs into resource problems.
+ * WRITE		A normal async write. Device will be plugged.
+ * SWRITE		Like WRITE, but a special case for ll_rw_block() that
+ *			tells it to lock the buffer first. Normally a buffer
+ *			must be locked before doing IO.
+ * WRITE_SYNC_PLUG	Synchronous write. Identical to WRITE, but passes down
+ *			the hint that someone will be waiting on this IO
+ *			shortly. The device must still be unplugged explicitly,
+ *			WRITE_SYNC_PLUG does not do this as we could be
+ *			submitting more writes before we actually wait on any
+ *			of them.
+ * WRITE_SYNC		Like WRITE_SYNC_PLUG, but also unplugs the device
+ *			immediately after submission. The write equivalent
+ *			of READ_SYNC.
+ * WRITE_ODIRECT	Special case write for O_DIRECT only.
+ * SWRITE_SYNC
+ * SWRITE_SYNC_PLUG	Like WRITE_SYNC/WRITE_SYNC_PLUG, but locks the buffer.
+ *			See SWRITE.
+ * WRITE_BARRIER	Like WRITE, but tells the block layer that all
+ *			previously submitted writes must be safely on storage
+ *			before this one is started. Also guarantees that when
+ *			this write is complete, it itself is also safely on
+ *			storage. Prevents reordering of writes on both sides
+ *			of this IO.

This is (again) a preparatory patch similar to commit
a2a9537ac0b37a5da6fbe7e1e9cb06c524d2a9c4. It open codes a simple
async way of executing do_thaw_all() out of context, so we can get
rid of pdflush.

Subject: cfq-iosched: don't delay queue kick for a merged request

"Zhang, Yanmin" <yanmin_zhang@linux.intel.com> reports that commit
b029195dda0129b427c6e579a3bb3ae752da3a93 introduced a regression
of about 50% with sequential threaded read workloads. The test
case is:

tiotest -k0 -k1 -k3 -f 80 -t 32

which starts 32 threads each reading a 80MB file. Twiddle the kick
queue logic so that we do start IO immediately, if it appears to be
a fully merged request. We can't really detect that, so just check
if the request is bigger than a page or not. The assumption is that
since single bio issues will first queue a single request with just
one page attached and then later do merges on that, if we already
have more than a page worth of data in the request, then the request
is most likely good to go.

Verified that this doesn't cause a regression with the test case that
commit b029195dda0129b427c6e579a3bb3ae752da3a93 was fixing. It does not,
we still see maximum sized requests for the queue-then-merge cases.

Subject: [ARM] 5449/1: S3C: Use disable_irq_nosync() to fix boot lockups

With 2.6.30-rc1 on SMDK6410 I experience a soft lockup on bootup when
the Samsung serial driver attempts to disable the transmit interrupt
from within the transmit interrupt handler: it calls disable_irq()
which locks up due to attempting to synchronise with the running handler.
Fix this by using disable_irq_nosync().

Also make the same change in the recieve path.

Subject: [ARM] 5450/1: Flush only the needed range when unmapping a VMA

When unmapping N pages (e.g. shared memory) the amount of TLB flushes
done can be (N*PAGE_SIZE/ZAP_BLOCK_SIZE)*N although it should be N at
maximum. With PREEMPT kernel ZAP_BLOCK_SIZE is 8 pages, so there is a
noticeable performance penalty when unmapping a large VMA and the system
is spending its time in flush_tlb_range().

The problem is that tlb_end_vma() is always flushing the full VMA
range. The subrange that needs to be flushed can be calculated by
tlb_remove_tlb_entry(). This approach was suggested by Hugh Dickins,
and is also used by other arches.

The speed increase is roughly 3x for 8M mappings and for larger mappings
even more.

Subject: GFS2: Fix symlink creation race

In certain cases symlinks can appear to have zero size if a lookup
on the inode occurs within a certain (very short) time after the
symlink has been created. The symlink is correctly created on disk
but appears to have zero size when stat()ed. This patch closes the
race and prevents incorrect sizes appearing.

Subject: splice: split up __splice_from_pipe()

Split up __splice_from_pipe() into four helper functions:

  splice_from_pipe_begin()
  splice_from_pipe_next()
  splice_from_pipe_feed()
  splice_from_pipe_end()

splice_from_pipe_next() will wait (if necessary) for more buffers to
be added to the pipe.  splice_from_pipe_feed() will feed the buffers
to the supplied actor and return when there's no more data available
(or if all of the requested data has been copied).

This is necessary so that implementations can do locking around the
non-waiting splice_from_pipe_feed().

This patch should not cause any change in behavior.

Subject: splice: remove i_mutex locking in splice_from_pipe()

splice_from_pipe() is only called from two places:

  - generic_splice_sendpage()
  - splice_write_null()

Neither of these require i_mutex to be taken on the destination inode.

Remove the now unused generic_file_splice_write_nolock() function.
It's conceptually broken anyway, because splice may need to wait for
pipe events so holding locks across the whole operation is wrong.

Subject: splice: add helpers for locking pipe inode

There are lots of sequences like this, especially in splice code:

	if (pipe->inode)
		mutex_lock(&pipe->inode->i_mutex);
	/* do something */
	if (pipe->inode)
		mutex_unlock(&pipe->inode->i_mutex);

so introduce helpers which do the conditional locking and unlocking.
Also replace the inode_double_lock() call with a pipe_double_lock()
helper to avoid spreading the use of this functionality beyond the
pipe code.

This patch is just a cleanup, and should cause no behavioral changes.

brd is always ordered (not that it matters, as it is defined not to
survive when the system goes down). So tell the block layer it is
ordered, which might be of help with testing filesystems.

Subject: brd: fix cacheflushing

brd is missing a flush_dcache_page. On 2nd thoughts, perhaps it is the
pagecache's responsibility to flush user virtual aliases (the driver of
course should flush kernel virtual mappings)... but anyway, there
already exists cache flushing for one direction of transfer, so we
should add the other.

Subject: cfq-iosched: tweak kick logic a bit more

We only kick the dispatch for an idling queue, if we think it's a
(somewhat) fully merged request. Also allow a kick if we have other
busy queues in the system, since we don't want to risk waiting for
a potential merge in that case. It's better to get some work done and
proceed.

Subject: cfq-iosched: add close cooperator code

If we have processes that are working in close proximity to each
other on disk, we don't want to idle wait. Instead allow the close
process to issue a request, getting better aggregate bandwidth.
The anticipatory scheduler has similar checks, noop and deadline do
not need it since they don't care about process <-> io mappings.

The code for CFQ is a little more involved though, since we split
request queues into per-process contexts.

This fixes a performance problem with eg dump(8), since it uses
several processes in some silly attempt to speed IO up. Even if
dump(8) isn't really a valid case (it should be fixed by using
CLONE_IO), there are other cases where we see close processes
and where idling ends up hurting performance.

Credit goes to Jeff Moyer <jmoyer@redhat.com> for writing the
initial implementation.

Subject: acpi-cpufreq: fix 'smp_call_function_many()' confusion

It turns out that 'smp_call_function_many()' doesn't work at all like
'smp_call_function_single()', and my change to Andrew's patch to use it
rather than a loop over all CPU's acpi-cpufreq doesn't work.

My bad.

'smp_call_function_many()' has two "features" (aka "documented bugs"):

 (a) it needs to be called with preemption disabled, because it uses
     smp_processor_id() without guarding the CPU lookup with 'get_cpu()'
     and 'put_cpu()' like the 'single' variant does.

 (b) even if the current CPU is part of the CPU mask, it won't do the
     call on that CPU.

Still, we're better off trying to use 'smp_call_function_many()' than
looping over CPU's, since it at least in theory allows us to use a
broadcast IPI and do it all in parallel.  So let's just work around the
silly semantic bugs in that function.

Subject: ALSA: hda - Fix the cmd cache keys for amp verbs

Fix the key value generation for get/set amp verbs.  The upper bits of
the parameter have to be combined with the verb value to be unique for
each direction/index of amp access.

This fixes the resume problem on some hardwares like Macbook after
the channel mode is changed.

Subject: Input: hp_sdc_rtc should depend on serio

Fix this build error when CONFIG_SERIO is not set
hp_sdc_rtc.c:691: undefined reference to `hp_sdc_request_timer_irq'
and so on..

"select should be used with care. select will force
a symbol to a value without visiting the dependencies."

Subject: Input: gameport - fix attach driver code

The commit 6902c0bead4ce266226fc0c5b3828b850bdc884a that moved
driver registration out of kgameportd thread was incomplete and
did not add the code necessary to actually attach driver to
already registered devices, rectify that.

Subject: MN10300: Stop gcc from generating uninitialised variable warnings
 after BUG()

Stop gcc from generating uninitialised variable warnings after BUG().  The
problem is that MN10300's implementation of BUG() invokes system call 15 which
doesn't return - but there's no way to tell the compiler that and also emit the
bug table element with the correct file and line data.

So instead, we make the do...while wrapper in _debug_bug_trap() an endless loop
from which there's no escape.

Also, while we're at it, (1) get rid of _debug_bug_trap() and just implement
directly as BUG(), and (2) make the implementation of BUG() contingent on
CONFIG_BUG=y.

Subject: RCU: Don't try and predeclare inline funcs as it upsets some versions
 of gcc

Don't try and predeclare inline funcs like this:

	static inline void wait_migrated_callbacks(void)
	...
	static void _rcu_barrier(enum rcu_barrier type)
	{
		...
		wait_migrated_callbacks();
	}
	...
	static inline void wait_migrated_callbacks(void)
	{
		wait_event(rcu_migrate_wq, !atomic_read(&rcu_migrate_type_count));
	}

as it upsets some versions of gcc under some circumstances:

	kernel/rcupdate.c: In function `_rcu_barrier':
	kernel/rcupdate.c:125: sorry, unimplemented: inlining failed in call to 'wait_migrated_callbacks': function body not available
	kernel/rcupdate.c:152: sorry, unimplemented: called from here

This can be dealt with by simply putting the static variables (rcu_migrate_*)
at the top, and moving the implementation of the function up so that it
replaces its forward declaration.

Subject: x86: disable X86_PTRACE_BTS for now

Oleg Nesterov found a couple of races in the ptrace-bts code
and fixes are queued up for it but they did not get ready in time
for the merge window. We'll merge them in v2.6.31 - until then
mark the feature as CONFIG_BROKEN. There's no user-space yet
making use of this so it's not a big issue.

Subject: Input: ads7846 - fix unsafe disable_irq

The use of disable_irq inside the handler for the interrupt being
disabled has always been dangerous.  disable_irq should wait for that
handler to complete before returning -> deadlock.

For some reason this wasn't actually the case until 3aa551c9b was merged
but since this time, the ads7846 driver has deadlocked the system on
first interrupt.

Convert the driver to use the handler-safe _nosync variant.

While cleaning up quirks, I noticed that there is a duplicated quirk for
the SSID 0x103c0934. Looking back through the bug reports, I've concluded
that there is only one necessary quirk (hp_mute_led), so this patch
removes the conflicting one.

Subject: ALSA: hda - Fix headphone-detection on some machines with STAC/IDT
 codecs

When the headphone can have no unique DAC, the current code doesn't
check the HP-detection although it should.  Put the hp-detection check
before the DAC check to fix this bug.

Add an export of the two GPIO configuration calls
s3c_gpio_cfgpin and s3c_gpio_setpull to allow modules
to use them (such as ASoC drivers)

Subject: imx21: activate i2c

Set the correct clkdev-name for the i2c clock.

It also get's rid of the ARCH_NR_GPIOS define on the rationale
that isn't an ARCH-wide setting anyway. If a device has two
pca953x devices, the reserved number will be wrong.

From c5ab660db9a98187667d017bb9425f0c1dc76ac1 Mon Sep 17 00:00:00 2001
From: Sascha Hauer
Date: Wed, 8 Apr 2009 11:39:34 +0200
Subject: mxc defconfig updates

This patch removes several i.MX board specific defconfig files in favour
for a mx1_defconfig, mx27_defconfig and mx3_defconfig. All config files
have all currently available boards, i.MX specific drivers and the network
device drivers for the boards enabled.

Subject: ASoC: pxa-ssp: allow setting of dai format 0

pxa_ssp_set_dai_fmt() currently has an early exit if the desired format
equals the current configuration. This is correct behaviour unless this
function is called with a zero value parameter for the first time.
Zero is a valid value for this function, but the early exit is bogus in
this case.

Hence, set priv->dai_fmt to -1 in the beginning so we can configure the
port.

bd25867a6cbe7a00ef7dbe8d9ddebc91b00b9b3f.

Thanks to Peter Ujfalusi <peter.ujfalusi@nokia.com> for noticing and being
part of the fix. Now the FS length definition is more clear by defining
it with  FWID(0).

Subject: ASoC: OMAP: Fix FS polarity in OSK5912 machine driver

Using inverted FS polarity in OSK5912 must be an error since TLV320AIC23
do not have support for inverted polarities. This is mostly due the hassle
with the DSP formats in OMAP McBSP DAI and inversion on OMAP side probably
just made this configuration working at some point.

Subject: Add block_write_full_page_endio for passing endio handler

block_write_full_page doesn't allow the caller to control what happens
when the IO is over.  This adds a new call named block_write_full_page_endio
so the buffer head end_io handler can be provided by the caller.

This will be used by the ext3 data=guarded mode to do i_size updates in
a workqueue based end_io handler.  end_buffer_async_write is also
exported so it can be called to do the dirty work of managing page
writeback for the higher level end_io handler.

Subject: powerpc/5200: Bring the legacy fsl_spi_platform_data hooks back

In commit 364fdbc00fbdd409ade63500710123fe323aa164 ("spi_mpc83xx:
rework chip selects handling"), I merged activate_cs and deactivate_cs
hooks into cs_control, but I overlooked that mpc52xx_psc_spi driver
is using these hooks too. And that resulted in the following build
failure:

CC      drivers/spi/mpc52xx_psc_spi.o
drivers/spi/mpc52xx_psc_spi.c: In function 'mpc52xx_psc_spi_do_probe':
drivers/spi/mpc52xx_psc_spi.c:398: error: 'struct fsl_spi_platform_data'
has no member named 'activate_cs'
drivers/spi/mpc52xx_psc_spi.c:399: error: 'struct fsl_spi_platform_data'
has no member named 'deactivate_cs'
make[2]: *** [drivers/spi/mpc52xx_psc_spi.o] Error 1

This patch simply adds the legacy hooks back for 2.6.30, and for
2.6.31 we'll convert the driver to ->cs_control.

Subject: x86: UV BAU distribution and payload MMRs

This patch correctly sets BAU memory mapped registers to point
to the sending activation descriptor table and target payload table.

The "Broadcast Assist Unit" is used for TLB shootdown in UV.

The memory mapped registers that point to sending and receiving
memory structures contain node numbers.

In one case the __pa() function did not provide the node id of
memory on blade zero in configurations where that id is nonzero.
In another case, it was assumed that memory was allocated on
the local node.  That assumption is not true in a configuration
in which the node has no memory.

Tested on the UV hardware simulator.

[ Impact: fix possible runtime crash due to incorrect TLB logic ]

Subject: drm/i915: allow tiled front buffers on 965+

This patch corrects a pretty big oversight in the KMS code for 965+
chips.  The current code is missing tiled surface register programming,
so userland can allocate a tiled surface and use it for mode setting,
resulting in corruption.  This patch fixes that, allowing for tiled
front buffers on 965+.

Subject: [IA64] smp_flush_tlb_mm() should only send IPI's to cpus in
 cpu_vm_mask

Having flush_tlb_mm->smp_flush_tlb_mm() send an IPI to every cpu
on the system is occasionally triggering spin_lock contention in
generic_smp_call_function_interrupt().

Follow x86 arch's lead and only sends IPIs to the cpus in mm->cpu_vm_mask.

Experiments with this change have shown significant improvement in this
contention issue.

Subject: libata: handle SEMB signature better

WDC WD1600JS-62MHB5 successfully hits the window between ATA/ATAPI-7
and Serial ATA II standards and reports 3c/c3 signature which now is
assigned to SEMB.  Make ata_dev_classify() report ATA_DEV_SEMB on the
sig and let ata_dev_read_id() work around it by trying IDENTIFY once.

This fixes bko#11579.

Subject: pata_hpt37x: fix HPT370 DMA timeouts

The libata driver has copied the code from the IDE driver which caused a post
2.4.18 regression on many HPT370[A] chips -- DMA stopped to work completely,
only causing timeouts.  Now remove hpt370_bmdma_start() for good...

Subject: pata_legacy: fix no device fail path

When pata_legacy can't detect any device, it unregisters the
platform_device and fails detection.  However, it forgets to detach
ata host triggering weird failures as the host later gets freed by
devres while still attached.  Fix it.

Subject: ata: Report 16/32bit PIO as best we can

The legacy old IDE ioctl API for this is a bit primitive so we try
and map stuff sensibly onto it.

- Set PIO over DMA devices to report 32bit
- Add ability to change the PIO32 settings if the controller permits it
- Add that functionality into the sff drivers
- Add that functionality into the VLB legacy driver
- Turn on the 32bit PIO on the ninja32 and add support there

Subject: [ARM] 5455/1: Fix IRQ noise from VIC code

The VIC code will attempt to perform som
default set_irq_chip() and set_irq_chip_data()
on all IRQs supported by the VIC, while the new
IRQ handling code strictly checks for the global
NR_IRQS to be respected also for these IRQs.

This patch will respect the interrupt mask passed
to the VIC driver and will prevent it from
attempting to call these functions on any unused
interrupts.

Subject: powerpc/of-device-tree: Factor MTD physmap bindings out of
 booting-without-of

It's easier to find bindings descriptions in separate files.  So factor
out the MTD physmap bindings into a separate file to not clutter
booting-without-of.txt more.

Subject: powerpc/device-tree: Document MTD nodes with multiple "reg" tuples

Add binding for mtd nodes with multiple reg tuples.  Multiple reg tuples
are used when the flash region covers multiple devices of the same type,
but not necessarily the same size.

Subject: Revert "kobject: don't block for each kobject_uevent".

This reverts commit f520360d93cdc37de5d972dac4bf3bdef6a7f6a7.

Tetsuo Handa, running a kernel with CONFIG_DEBUG_PAGEALLOC=y and
CONFIG_UEVENT_HELPER_PATH=/sbin/hotplug, has been hitting RCU detected
CPU stalls: it's been spinning in the loop where do_execve() counts up
the args (but why wasn't fixup_exception working? dunno).

The recent change, switching kobject_uevent_env() from UMH_WAIT_EXEC
to UMH_NO_WAIT, is broken: the exec uses args on the local stack here,
and an env which is kfreed as soon as call_usermodehelper() returns.
It very much needs to wait for the exec to be done.

An alternative would be to keep the UMH_NO_WAIT, and complicate the code
to allocate and free these resources correctly? but no, as GregKH
pointed out when making the commit, CONFIG_UEVENT_HELPER_PATH="" is a
much better optimization - though some distros are still saying
/sbin/hotplug in their .config, yet with no such binary in their initrd
or their root.

Subject: mm: pass correct mm when growing stack

Tetsuo Handa reports seeing the WARN_ON(current->mm == NULL) in
security_vm_enough_memory(), when do_execve() is touching the
target mm's stack, to set up its args and environment.

Yes, a UMH_NO_WAIT or UMH_WAIT_PROC call_usermodehelper() spawns
an mm-less kernel thread to do the exec.  And in any case, that
vm_enough_memory check when growing stack ought to be done on the
target mm, not on the execer's mm (though apart from the warning,
it only makes a slight tweak to OVERCOMMIT_NEVER behaviour).

Subject: x86, PAT: Remove page granularity tracking for vm_insert_pfn maps

This change resolves the problem of too many single page entries
in pat_memtype_list and "freeing invalid memtype" errors with i915,
reported here:

  http://marc.info/?l=linux-kernel&m=123845244713183&w=2

Remove page level granularity track and untrack of vm_insert_pfn.
memtype tracking at page granularity does not scale and cleaner
approach would be for the driver to request a type for a bigger
IO address range or PCI io memory range for that device, either at
mmap time or driver init time and just use that type during
vm_insert_pfn.

This patch just removes the track/untrack of vm_insert_pfn. That
means we will be in same state as 2.6.28, with respect to these APIs.

Newer APIs for the drivers to request a memtype for a bigger region
is coming soon.

[ Impact: fix Xorg startup warnings and hangs ]

Subject: sched: Avoid printing sched_group::__cpu_power for default case

Commit 46e0bb9c12f4 ("sched: Print sched_group::__cpu_power
in sched_domain_debug") produces a messy dmesg output while
attempting to print the sched_group::__cpu_power for each
group in the sched_domain hierarchy.

Fix this by avoid printing the __cpu_power for default cases.
(i.e, __cpu_power == SCHED_LOAD_SCALE).

Keep sysfs files around for cpus even when we failed to locate

Subject: sysfs: don't use global workqueue in sysfs_schedule_callback()

A sysfs attribute using sysfs_schedule_callback() to commit suicide
may end up calling device_unregister(), which will eventually call
a driver's ->remove function.

Drivers may call flush_scheduled_work() in their shutdown routines,
in which case lockdep will complain with something like the following:

Although we know that the device_unregister path will never acquire
a lock that a driver might try to acquire in its ->remove, in general
we should never attempt to flush a workqueue from within the same
workqueue, and lockdep rightly complains.

So as long as sysfs attributes cannot commit suicide directly and we
are stuck with this callback mechanism, put the sysfs callbacks on
their own workqueue instead of the global one.

This has the side benefit that if a suicidal sysfs attribute kicks
off a long chain of ->remove callbacks, we no longer induce a long
delay on the global queue.

This also fixes a missing module_put in the error path introduced
by sysfs-only-allow-one-scheduled-removal-callback-per-kobj.patch.

We never destroy the workqueue, but I'm not sure that's a
problem.

Subject: sysfs: sysfs poll keep the poll rule of regular file.

Currently, following test programs don't finished.

% ruby -e '
Thread.new { sleep }
File.read("/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies")
'

strace expose the reason.

...
open("/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies", O_RDONLY|O_LARGEFILE) = 3
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbf9fa6b8) = -1 ENOTTY (Inappropriate ioctl for device)
fstat64(3, {st_mode=S_IFREG|0444, st_size=4096, ...}) = 0
_llseek(3, 0, [0], SEEK_CUR)            = 0
select(4, [3], NULL, NULL, NULL)        = 1 (in [3])
read(3, "1400000 1300000 1200000 1100000 1"..., 4096) = 62
select(4, [3], NULL, NULL, NULL


Because Ruby (the scripting language) VM assume select system-call
against regular file don't block.  it because SUSv3 says "Regular files
shall always poll TRUE for reading and writing".  see
http://www.opengroup.org/onlinepubs/009695399/functions/poll.html it
seems valid assumption.

But sysfs_poll() don't keep this rule although sysfs file can read and
write always.

This patch restore proper poll behavior to sysfs.
/sys/block/md*/md/sync_action polling application and another sysfs
updating sensitive application still can use POLLERR and POLLPRI.

Subject: proc: mounts_poll() make consistent to mdstat_poll

In recently sysfs_poll discussion, Neil Brown pointed out /proc/mounts
also should be fixed.

SUSv3 says "Regular files shall always poll TRUE for reading and
writing".  see
http://www.opengroup.org/onlinepubs/009695399/functions/poll.html

Then, mounts_poll()'s default should be "POLLIN | POLLRDNORM".  it mean
always readable.

In addition, event trigger should use "POLLERR | POLLPRI" instead
POLLERR.  it makes consistent to mdstat_poll() and sysfs_poll(). and,
select(2) can handle POLLPRI easily.

Subject: Driver Core: early platform driver

V3 of the early platform driver implementation.

Platform drivers are great for embedded platforms because we can separate
driver configuration from the actual driver.  So base addresses,
interrupts and other configuration can be kept with the processor or board
code, and the platform driver can be reused by many different platforms.

For early devices we have nothing today.  For instance, to configure early
timers and early serial ports we cannot use platform devices.  This
because the setup order during boot.  Timers are needed before the
platform driver core code is available.  The same goes for early printk
support.  Early in this case means before initcalls.

These early drivers today have their configuration either hard coded or
they receive it using some special configuration method.  This is working
quite well, but if we want to support both regular kernel modules and
early devices then we need to have two ways of configuring the same
driver.  A single way would be better.

The early platform driver patch is basically a set of functions that allow
drivers to register themselves and architecture code to locate them and
probe.  Registration happens through early_param().  The time for the
probe is decided by the architecture code.

See Documentation/driver-model/platform.txt for more details.

       be probed later if another device registers.  (Which is OK, since
       this interface is only for use with non-hotpluggable devices.)
 
+
+Early Platform Devices and Drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The early platform interfaces provide platform data to platform device
+drivers early on during the system boot. The code is built on top of the
+early_param() command line parsing and can be executed very early on.
+
+Example: "earlyprintk" class early serial console in 6 steps
+
+1. Registering early platform device data
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The architecture code registers platform device data using the function
+early_platform_add_devices(). In the case of early serial console this
+should be hardware configuration for the serial port. Devices registered
+at this point will later on be matched against early platform drivers.
+
+2. Parsing kernel command line
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The architecture code calls parse_early_param() to parse the kernel
+command line. This will execute all matching early_param() callbacks.
+User specified early platform devices will be registered at this point.
+For the early serial console case the user can specify port on the
+kernel command line as "earlyprintk=serial.0" where "earlyprintk" is
+the class string, "serial" is the name of the platfrom driver and
+0 is the platform device id. If the id is -1 then the dot and the
+id can be omitted.
+
+3. Installing early platform drivers belonging to a certain class
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The architecture code may optionally force registration of all early
+platform drivers belonging to a certain class using the function
+early_platform_driver_register_all(). User specified devices from
+step 2 have priority over these. This step is omitted by the serial
+driver example since the early serial driver code should be disabled
+unless the user has specified port on the kernel command line.
+
+4. Early platform driver registration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Compiled-in platform drivers making use of early_platform_init() are
+automatically registered during step 2 or 3. The serial driver example
+should use early_platform_init("earlyprintk", &platform_driver).
+
+5. Probing of early platform drivers belonging to a certain class
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The architecture code calls early_platform_driver_probe() to match
+registered early platform devices associated with a certain class with
+registered early platform drivers. Matched devices will get probed().
+This step can be executed at any point during the early boot. As soon
+as possible may be good for the serial port case.
+
+6. Inside the early platform driver probe()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The driver code needs to take special care during early boot, especially
+when it comes to memory allocation and interrupt registration. The code
+in the probe() function can use is_early_platform_device() to check if
+it is called at early platform device or at the regular platform device
+time. The early serial driver performs register_console() at this point.
+

Subject: dynamic debug: resurrect old pr_debug() semantics as pr_devel()

pr_debug() used to produce zero code unless DEBUG was #defined.  This is
now no longer the case in practice[1].

There are places where it's useful to have debugging printks, but we don't
want them to generate any code in production kernels.

So add a new macro, pr_devel(), for _devel_opment, to provide the old
semantics, ie.  if the programmer doesn't explicitly enable debugging, no
code is produced.

[1]: You can turn CONFIG_DYNAMIC_DEBUG off, but it's enabled in at least
     one distro kernel, so it's not really a solution.

Subject: driver core: prevent device_for_each_child from oopsing

David Vrabel noticed that the wireless usb stack likes to call
device_for_each_chile() with an empty bus.  This used to work fine, but
now oopses.  This patch fixes the oops and makes the code behave like it
used to.

Subject: Driver core: remove pr_fmt() from dynamic_dev_dbg() printk

When pr_fmt() was added to the pr_debug() code, we added it not only to the
dynamic_pr_debug() function, but also to the dynamic_dev_dbg() funciton.
However, dev_dbg() doesn't make use of pr_fmt(), so neither should
dynamic_dev_dbg().

+ * read_barrier_depends - Flush all pending reads that subsequents reads
+ * depend on.
+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier.  All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads.  This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies.  See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ *      CPU 0                           CPU 1
+ *
+ *      b = 2;
+ *      memory_barrier();
+ *      p = &b;                         q = p;
+ *                                      read_barrier_depends();
+ *                                      d = *q;
+ * </programlisting>
+ *
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends().  However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ *      CPU 0                           CPU 1
+ *
+ *      a = 2;
+ *      memory_barrier();
+ *      b = 3;                          y = b;
+ *                                      read_barrier_depends();
+ *                                      x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b".  Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
+ * in cases like this where there are no data dependencies.

+ *	but it may come in handy at some point.  All of the registers
+ *	are stored as part of the upage.  The upage should always be
+ *	only one page.
+ * DATA: The data area is stored.  We use current->end_text to
+ *	current->brk to pick up all of the user variables, plus any memory
+ *	that may have been sbrk'ed.  No attempt is made to determine if a
+ *	page is demand-zero or if a page is totally unused, we just cover
+ *	the entire range.  All of the addresses are rounded in such a way
+ *	that an integral number of pages is written.
+ * STACK: We need the stack information in order to get a meaningful
+ *	backtrace.  We need to write the data from usp to
+ *	current->start_stack, so we round each of these off in order to be
+ *	able to write an integer number of pages.

- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads.  This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies.  See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- *      CPU 0                           CPU 1
- *
- *      b = 2;
- *      memory_barrier();
- *      p = &b;                         q = p;
- *                                      read_barrier_depends();
- *                                      d = *q;
- * </programlisting>
- *
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends().  However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- *      CPU 0                           CPU 1
- *
- *      a = 2;
- *      memory_barrier();
- *      b = 3;                          y = b;
- *                                      read_barrier_depends();
- *                                      x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b".  Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
- * in cases like this where there are no data dependencies.

Subject: md: update sync_completed and reshape_position even more often.

There are circumstances when a user-space process might need to
"oversee" a resync/reshape process.  For example when doing an
in-place reshape of a raid5, it is prudent to take a backup of each
section before reshaping it as this is the only way to provide
safety against an unplanned shutdown (i.e. crash/power failure).

The sync_max sysfs value can be used to stop the resync from
advancing beyond a particular point.
So user-space can:
  suspend IO to the first section and back it up
  set 'sync_max' to the end of the section
  wait for 'sync_completed' to reach that point
  resume IO on the first section and move on to the next section.

However this process requires the kernel and user-space to run in
lock-step which could introduce unnecessary delays.

It would be better if a 'double buffered' approach could be used with
userspace and kernel space working on different sections with the
'next' section always ready when the 'current' section is finished.

One problem with implementing this is that sync_completed is only
guaranteed to be updated when the sync process reaches sync_max.
(it is updated on a time basis at other times, but it is hard to rely
on that).  This defeats some of the double buffering.

With this patch, sync_completed (and reshape_position) get updated as
the current position approaches sync_max, so there is room for
userspace to advance sync_max early without losing updates.

To be precise, sync_completed is updated when the current sync
position reaches half way between the current value of sync_completed
and the value of sync_max.  This will usually be a good time for user
space to update sync_max.

If sync_max does not get updated, the updates to sync_completed
(together with associated metadata updates) will occur at an
exponentially increasing frequency which will get unreasonably fast
(one update every page) immediately before the process hits sync_max
and stops.  So the update rate will be unreasonably fast only for an
insignificant period of time.

Subject: x86/irq: mark NUMA_MIGRATE_IRQ_DESC broken

It causes crash on system with lots of cards with MSI-X
when irq_balancer enabled...

The patches fixing it were both complex and fragile, according
to Eric they were also doing quite dangerous things to the
hardware.

Instead we now have patches that solve this problem via static
NUMA node mappings - not dynamic allocation and balancing.

The patches are much simpler than this method but are still too
large outside of the merge window, so we mark the dynamic balancer
as broken for now, and queue up the new approach for v2.6.31.

[ Impact: deactivate broken kernel feature ]

Subject: cifs: flush data on any setattr

We already flush all the dirty pages for an inode before doing
ATTR_SIZE and ATTR_MTIME changes. There's another problem though -- if
we change the mode so that the file becomes read-only then we may not
be able to write data to it after a reconnect.

Fix this by just going back to flushing all the dirty data on any
setattr call. There are probably some cases that can be optimized out,
but I'm not sure they're worthwhile and we need to consider them more
carefully to make sure that we don't cause regressions if we have
to reconnect before writeback occurs.

Subject: [CIFS] Endian convert UniqueId when reporting inode numbers from
 server files

Jeff made a good point that we should endian convert the UniqueId when we use
it to set i_ino Even though this value is opaque to the client, when comparing
the inode numbers of the same server file from two different clients (one
big endian, one little endian) or when we compare a big endian client's view
of i_ino with what the server thinks - we should get the same value

didn't start at the eof were done.

The first patch also didn't update the size correctly when it explicitly
set via truncate().

This patch adds code to track the client's current understanding of the
size of the file on the server separate from the i_size, and then to use
this info to semi-intelligently set the timeout for writes past the EOF.

This helps prevent timeouts when trying to write large, sparse files on
windows servers.

cifs: remove dnotify thread code

Al Viro recently removed the dir_notify code from the kernel along with
the CIFS code that used it. We can also get rid of the dnotify thread
as well.

In actuality, it never had anything to do with dir_notify anyway. All
it did was unnecessarily wake up all the tasks waiting on the response
queues every 15s. Previously that happened to prevent tasks from hanging
indefinitely when the server went unresponsive, but we put those to
sleep with proper timeouts now so there's no reason to keep this around.

cifs: no need to use rcu_assign_pointer on immutable keys

Neither keytype in use by CIFS has an "update" method. This means that
the keys are immutable once instantiated. We don't need to use RCU
to set the payload data pointers.

Subject: cifs: fix unicode string area word alignment in session setup

The handling of unicode string area alignment is wrong.
decode_unicode_ssetup improperly assumes that it will always be preceded
by a pad byte. This isn't the case if the string area is already
word-aligned.

This problem, combined with the bad buffer sizing for the serverDomain
string can cause memory corruption. The bad alignment can make it so
that the alignment of the characters is off. This can make them
translate to characters that are greater than 2 bytes each. If this
happens we can overflow the allocation.

Fix this by fixing the alignment in CIFS_SessSetup instead so we can
verify it against the head of the response. Also, clean up the
workaround for improperly terminated strings by checking for a
odd-length unicode buffers and then forcibly terminating them.

Finally, resize the buffer for serverDomain. Now that we've fixed
the alignment, it's probably fine, but a malicious server could
overflow it.

A better solution for handling these strings is still needed, but
this should be a suitable bandaid.

Subject: cifs: fix buffer size for tcon->nativeFileSystem field

The buffer for this was resized recently to fix a bug. It's still
possible however that a malicious server could overflow this field
by sending characters in it that are >2 bytes in the local charset.
Double the size of the buffer to account for this possibility.

Also get rid of some really strange and seemingly pointless NULL
termination. It's NULL terminating the string in the source buffer,
but by the time that happens, we've already copied the string.

Subject: cifs: remove unneeded bcc_ptr update in CIFSTCon

This pointer isn't used again after this point. It's also not updated in
the ascii case, so there's no need to update it here.

Subject: HID: Add support for the G25 force feedback wheel in native mode

Add Product Id 0xc299 for the Logitech G25 force feedback wheel
The Logitech G25 force feedback wheel, is first recognize by the kernel
with the product id "0xc294". In this mode, we can't use all the axes
and buttons of the wheel.

Using a userland utility, it is possible to make the wheel switch to native
mode -- http://svn.vdrift.net/viewvc.cgi/trunk/tools/G25manage/?root=VDrift
In native mode, the wheel change its id number to "0xc299".

The packet that needs to be sent to the wheel to swtich to native mode and
change its PID is

	{ 0xf8, 0x10, 0x00, 0x00, 0x00, 0x00, 0x00 }

Subject: ALSA: us122l: Fix signedness in comparisions

Within 2.6.30's mergewindow, struct urb's transfer_buffer_length has become
unsigned. This changed an "int > int" comparision to an "unsigned > int" one
in snd_usb_122l.
Fix this by using a local int variable instead of urb->transfer_buffer_length
in comparisions.

Shorten playback_prep_freqn() a bit and tweak error-paths in
usb_stream_prepare_playback().

Those macros are just screwed as soon as CONFIG_PXA25x is enabled.

This patch
- changes ssp_set_scr to take an ssp_dev pointer instead of ssp_device
- adds a corresponding ssp_get_scr function.

Ah, nice catch. I think we should put at least the name in regardless.

Ensure we at least initialize the trivial entries of the depmap so that
they can be relied upon, even when lockdep itself decided to pack up and
go home.

[ Impact: fix lock tracing after lockdep warnings. ]

timer handler - new files" and 758db3f2118703a1e36374dae5d58bed963e7e0d:
"[h8300] move include/asm-h8300 to arch/h8300/include/asm" for details).

This also removes a left-over .gitignore file in include/asm-arm that
became stale when the ARM header files were moved (which happened in
multiple commits, just see "git log -- include/asm-arm" for details).

Subject: usb gadget: fix ethernet link reports to ethtool

The g_ether USB gadget driver currently decides whether or not there's a
link to report back for eth_get_link based on if the USB link speed is
set. The USB gadget speed is however often set even before the device is
enumerated. It seems more sensible to only report a "link" if we're
actually connected to a host that wants to talk to us. The patch below
does this for me - tested with the PXA27x UDC driver.

It is an express card but was only tested with the provided usb adapter as I
don't have machines with express card connector.

Subject: USB: musb_host, fix ep0 fifo flushing

The MUSB host side can't share generic TX FIFO flush logic
with EP0; the EP0 TX status register bits are different
from those for other entpoints.

Resolve this issue by providing a new EP0-specific routine
to flush and reset the FIFO, which pays careful attention to
restrictions listed in the latest programmer's guide.  This
gets rid of an open issue whereby the usbtest control write
test (#14) failed.

Subject: USB: musb: bugfixes for multi-packet TXDMA support

We really want to use DMA mode 1 for all multi-packet transfers;
that's one IRQ on DMA completion, instead of one per packet.

There is an important issue with such transfers, especially on
the host side:  when such transfers end with a full-size packet,
we must defer musb_dma_completion() calls until the FIFO empties.
Else we report URB completions too soon, and may clobber data in
the FIFO fifo when writing the next packet (losing data).

The Inventra DMA support uses DMA mode 1, but it ignores that
issue.  The CPPI DMA support uses mode 0, but doesn't handle
its TXPKTRDY interrupts quite right either; it can get stale
"packet ready" interrupts, and report transfer completion too
early using slightly different code paths, also losing data.

So I'm solving it in a generic way -- by adding a sort of the
"interrupt filter" into musb_host_tx(), catching these cases
where a DMA completion IRQ doesn't suffice and removing some
needlessly controller-specific logic.  When a TXDMA interrupt
happens and DMA request mode 1 is active, that filter resets
to mode 0 and defers URB completion processing until TXPKTRDY,
unless the FIFO is already empty.  Related filtering logic in
Inventra and CPPI code gets removed.

Since it should be competely safe now to use the DMA request
mode 1 for host side transfers with the CPPI DMA controller,
set it in musb_h_tx_dma_start() ... now renamed (and shared).

Subject: USB: musb: sanitize clearing TXCSR DMA bits (take 2)

The MUSB code clears TXCSR_DMAMODE incorrectly in several
places, either asserting that TXCSR_DMAENAB is clear (when
sometimes it isn't) or clearing both bits together.  Recent
versions of the programmer's guide require DMAENAB to be
cleared first, although some older ones didn't.

Fix this and while at it:

 - In musb_gadget::txstate(), stop clearing the AUTOSET
   and DMAMODE bits for the CPPI case since they never
   get set anyway (the former bit is reserved on DaVinci);
   but do clear the DMAENAB bit on the DMA error path.

 - In musb_host::musb_ep_program(), remove the duplicate
   DMA controller specific code code clearing the TXCSR
   previous state, add the code to clear TXCSR DMA bits
   on the Inventra DMA error path, to replace such code
   (executed late) on the PIO path.

 - In musbhsdma::dma_channel_abort()/dma_controller_irq(),
   add/use the 'offset' variable to avoid MUSB_EP_OFFSET()
   invocations on every RXCSR/TXCSR access.

From 6b6e97107f12f3a9f7b5b43a6c3b94409240bcff Mon Sep 17 00:00:00 2001
From: Sergei Shtylyov
Date: Thu, 26 Mar 2009 18:29:19 -0700
Subject: USB: musb: fix isochronous TXDMA (take 2)

Multi-frame isochronous TX URBs transfers in DMA mode never
complete with CPPI DMA because musb_host_tx() doesn't restart
DMA on the second frame, only emitting a debug message.
With Inventra DMA they complete, but in PIO mode.  To fix:

 - Factor out programming of the DMA transfer from
   musb_ep_program() into musb_tx_dma_program();

 - Reorder the code at the end of musb_host_tx() to
   facilitate the fallback to PIO iff DMA fails;

 - Handle the buffer offset consistently for both
   PIO and DMA modes;

 - Add an argument to musb_ep_program() for the same
   reason (it only worked correctly with non-zero
   offset of the first frame in PIO mode);

 - Set the completed isochronous frame descriptor's
   'actual_length' and 'status' fields correctly in
   DMA mode.

Also, since CPPI reportedly doesn't like sending isochronous
packets in the RNDIS mode, change the criterion for this
mode to be used only for multi-packet transfers.  (There's
no need for that mode in the single-packet case anyway.)

From f4c1a8379a6d1ba39ac7b87f75d1352ef05cffff Mon Sep 17 00:00:00 2001
From: Werner Cornelius
Date: Fri, 16 Jan 2009 21:02:41 +0100
Subject: USB: usb-serial ch341: support for DTR/RTS/CTS

commit 664d5df92e88b6ef091048a802b3750f4e989180 upstream.

Fixup of Werner Cornelius patch to the ch341 USB-serial driver, which adds:
- support all baudrates, not just a hard-coded set
- support for controlling DTR, RTS and CTS

Features still missing:
- character length other than 8 bits
- parity settings
- break control

I adapted his patch for the new usb_serial API introduced in 2.6.25-git8 by
Alan Cox on 22 July 2008. Non-compliance to the new API was a reason for
refusing a similar patch from Tollef Fog Heen.

Usage example by Tollef Fog Heen :
        TEMPer USB thermometer <http://err.no/src/TEMPer.c>

based on a patch by:

	From: Tollef Fog Heen <tfheen@err.no>

	* Implement support for all baud rates rather than just a hard
	  coded set.
	* Make it possible to control status and control lines
	* Grab a bunch of #defines from FreeBSD to reduce the number of
	  magic numbers in the file

Subject: usb-storage: fix mistake in Makefile

This patch (as1228) fixes a Makefile error introduced when the
subdrivers in usb-storage were split out into separate modules.  The
intention is that when CONFIG_USB_LIBUSUAL is set, libusual.o and
usual-tables.o should be combined into a single object file (called
usb-libusual).  The current Makefile will instead create two separate
objects, and the result won't load properly.

Subject: USB device codes for Motorola phone.

The v950 appears to be a ruggedized version of the Motorola Razor
phone.  Tethering to the phone to use it in 'phone as modem' mode
requires the use of the specialized moto-modem driver which layers
over the usb-serial driver.  Support for the v950 was added simply
adding the device ID's for the phone.

Subject: USB: add reset endpoint operations

Wireless USB endpoint state has a sequence number and a current
window and not just a single toggle bit.  So allow HCDs to provide a
endpoint_reset method and call this or clear the software toggles as
required (after a clear halt, set configuration etc.).

usb_settoggle() and friends are then HCD internal and are moved into
core/hcd.h and all device drivers call usb_reset_endpoint() instead.

If the device endpoint state has been reset (with a clear halt) but
the host endpoint state has not then subsequent data transfers will
not complete. The device will only work again after it is reset or
disconnected.

From: David Vrabel
Date: Wed, 8 Apr 2009 17:36:29 +0000
Subject: USB: whci-hcd: provide a endpoint_reset method

Provide a endpoint_reset method to reset sequence number and current
window.  This QHead information can only be changed while the qset is
not in a schedule.

Subject: USB: whci-hcd: check return value of usb_hcd_link_urb_to_ep()

Check the return value of usb_hcd_link_urb_to_ep() and do not add the
urb to the ASL/PZL if it returns an error.

Omitting the check results in urbs that appear to be submitted
successfully but then cannot be unliked (because
usb_hcd_check_unlink_urb() returns an error).  This can cause khubd (for
example) to block forever in usb_kill_urb().

Subject: Staging: binder: Keep a reference to the files_struct while the
 driver is mmapped

This prevents breaking fget_light if a single threaded application
allows incoming file descriptors (in replies or on nodes).
Should also prevent inserting a file in the wrong files_struct if the
receving process execs in the middle of a transaction (between
task_get_unused_fd_flags and task_fd_install).

Subject: Staging: binder: Defer flush and release operations to avoid
 deadlocks.

If a transaction that contains a file descriptor fails on a later object,
the new file descriptor needs to be closed. If this is a binder file
descriptor we would deadlock in flush. If there were no other references to
the file at this point release would also be called.

Subject: Staging: sxg: Fix leaks and checksum errors in transmit code path

Fix the transmit function for the following:
* Free XmtCmd in the error code path. This use to leak memory in
  error conditions.
* Do pci mapping after the checksum operations are over. They can
  reallocate the skb at a different location.
* Fix UDP checksum errors which were seen in wireshark

Subject: Staging: go7007: fix build issues

Now that TUNER_SET_TYPE_ADDR is gone from the tree, the older code kicks
in and tries to use TUNER_SET_TYPE, which went away a long time ago.

This patch removes all of this logic, as it should not be needed anymore
now, and by doing so, fixes the build.

Fix an endcase in the UV initialization code for the "UV large system mode"
of apicids.  If node zero contains no cpus, cpus on another node will be the
boot cpu.  The percpu data that contains the extra apicid bits was not
being initialized early enough.

Subject: x86, kbuild: make "make install" not depend on vmlinux

It is common to use "make install" in restricted environments which
differ from the one which was actually used to build the kernel.  In
such environments it is highly undesirable to trigger a rebuild of any
part of the system.  Worse, the rebuild may be spurious, triggered by
differences in the environment.

Subject: sata_mv: workaround for multi_count errata sata24

Workaround for errata SATA#24 in sata_mv.
This errata affects WRITE_MULTI* commands when
the device multi_count produces a DRQ block size >= 4Kbytes.

We work around it here by converting such operations
into ordinary PIO_WRITEs instead.

Note that this might result in a PIO FUA write unavoidably being converted
into a non-FUA write.  In practice, any system using FUA is also going to be
using DMA rather than PIO, so this shouldn't affect anyone in the real world.

Subject: pata_via: Cache and rewrite the device bit

Some VIA chipsets will reset the DEV bit after IEN changes on ctl. Our
optimised write path avoids doing this but we need to remove the
optimisation on these devices.

[Identified and some original patches proposed by Josehn Chan @ VIA but
discussion then all ground to a halt so given a test case I dug it back out]

Subject: ACPI: Disable _GTS and _BFS support by default

Executing BIOS code paths not exercised by Windows
tends to get Linux into trouble.

However, if a system does benefit from _GTS or _BFS,
acpi.gts=1 an acpi.bfs=1 are now available to enable them.

Subject: thinkpad-acpi: fix LED blinking through timer trigger

The set_blink hook code in the LED subdriver would never manage to get
a LED to blink, and instead it would just turn it on.  The consequence
of this is that the "timer" trigger would not cause the LED to blink
if given default parameters.

This problem exists since 2.6.26-rc1.

To fix it, switch the deferred LED work handling to use the
thinkpad-acpi-specific LED status (off/on/blink) directly.

This also makes the code easier to read, and to extend later.

Subject: thinkpad-acpi: simplify module autoloading

Simplify the module autoloading a great deal, by keying to the HID for
the HKEY interface.

Only _really_ ancient IBM ThinkPad models like the 240, 240x and 570
lack the HKEY interface, and they're getting their own trimmed-down
driver one of these days.

Plenty of high-profile changes, so it deserves a new version number.

Features added since 0.22:
 *  Restrict unsafe LEDs
 *  New race-less brightness control strategy for IBM ThinkPads
 *  Disclose TGID of driver access from userspace (debug)
 *  Warn when deprecated functions are used

Other changes:
 *  Better debug messages in some subdrivers
 *  Removed "hotkey disable" support, since it breaks the driver
 *  Dropped "ibm-acpi" alias

I hit the check_flags error of lockdep:

 WARNING: at kernel/lockdep.c:2893 check_flags+0x1a7/0x1d0()
 [...]
 hardirqs last  enabled at (12567): [<ffffffff8026206a>] local_bh_enable+0xaa/0x110

 softirqs last disabled at (12568): [<ffffffff8058454e>] tcp_prequeue_process+0x2e/0xa0

The check_flags warning of lockdep tells me that lockdep thought interrupts
were disabled, but they were really enabled.

The numbers in the above parenthesis show the order of events:

 12566: softirqs last enabled:  lock_sock_nested
 12567: hardirqs last enabled:  local_bh_enable
 12568: softirqs last disabled: tcp_prequeue_process
 12566: hardirqs last disabled: int3

int3 is a breakpoint!

Examining this further, I have CONFIG_NET_TCPPROBE enabled which adds
break points into the kernel.

The paranoid_exit of the return of int3 does not account for enabling
interrupts on return to kernel. This code is a bit tricky since it
is also used by the nmi handler (when lockdep is off), and we must be
careful about the swapgs. We can not call kernel code after the swapgs
has been performed.

[ Impact: fix lockdep check_flags warning + self-turn-off ]

The culprit has been identified (at last!): it turned to be the code resetting
the DMA state machine before each transfer. Stop doing it now as this counter-
measure has clearly caused more harm than good.

This should fix the kernel.org bug #7703.

Commit d979677c4c0 ("mm: shrink_all_memory(): use sc.nr_reclaimed")
broke the memory shrinking used by hibernation, becuse it did not update
shrink_all_zones() in accordance with the other changes it made.

Fix this by making shrink_all_zones() update sc->nr_reclaimed instead of
overwriting its value.

Subject: Input: elantech - provide a workaround for jumpy cursor on firmware
 2.34

It seems that Elantech touchpad firmware version 2.34 on the Hercules eCAFÉ
suffers from a problem where bogus coordinates get reported at the beginning
of a touch action. This causes the mouse cursor or the scrolled page to
jump.

Included patch provides a workaround that discards mouse packets that are
likely to contain bogus coordinates. The workaround is activated when we
detect touchpad with fimware version 2.34.

Subject: Input: elantech - make sure touchpad is really in absolute mode

There exist laptops with Elantech touchpads where switching to absolute mode
does not happen, although writing the configuration register succeeds
without error. Reading back the register afterwards reveils that the
absolute mode bit is not set as if masked out by the touchpad firmware.

Always read back register 0x10, make sure that for hardware version 1 the
absolute mode bit is actually set and fail otherwise. This prevents the case
where the touchpad is claimed by the Elantech driver but is nonetheless not
working.

Subject: Remove 'recurse into child resources' logic from
 'reserve_region_with_split()'

This function is not actually used right now, since the original use
case for it was done with insert_resource_expand_to_fit() instead.

However, we now have another usage case that wants to basically do a
"reserve IO resource, splitting around existing resources", however that
one doesn't actually want the "recurse into the conflicting resource"
logic at all.

And since recursing into the conflicting resource was the most complex
part, and isn't wanted, just remove it.  Maybe we'll some day want both
versions, but we can just resurrect the logic then.

Subject: mtd: expose subpage size via sysfs

MTD has got sysfs support in 2.6.30-rc1. But subpage size is not
exposed there - do this.

UBI utilities badly need this parameter. At the moment there is
no way to get subpage size - ioctls do not return it. And we
just got sysfs support, so we can easilly extend it with this
additional parameter.

This can be merged late in the development cycle because:
1. sysfs support has been just added - there are no users for
   it so far, even.
2. UBI utilities really need this parameter, and it is better
   not to delay this.

Subject: kbuild: support include/generated

We need a location for generated files.
Today they are spread over several places and bringing them
together to a common place makes it obvious hat is generated
and what isreal files.

Al Viro originally suggested: include/gen
Linus suggested to spell it out.

This patch implement support for

    include/generated

All files in include/generated are ignored by git.
include/generated is removed during "make mrproper".

With this we are ready to implement support for include/generated
in the various architctures and in the base kernel.

Subject: kbuild: introduce subdir-ccflags-y

Following patch introduce support for setting options
to gcc that has effect for current directory and all
subdirectories.

The typical use case are an architecture or a subsystem that
decide to cover all files with -Werror.
Today alpha, mips and sparc uses -Werror in almost all their
Makefile- with subdir-ccflag-y it is now simpler to do so
as only the top-level directories needs to be covered.

Likewise if we decide to cover a full subsystem such
as net/ with -Werror this is done by adding a single
line to net/Makefile.

Subject: lguest: fix crash on vmlinux images

Typical message: 'lguest: unhandled trap 6 at 0x418726 (0x0)'

vmlinux guests were broken by 4cd8b5e2a159f18a1507f1187b44a1acbfa6341b
'lguest: use KVM hypercalls', which rewrites guest text from kvm hypercalls
to trap 31.

The Launcher mmaps the kernel image.  The Guest executes and
immediately faults in the first text page (read-only).  Then it hits a
hypercall, and we rewrite that hypercall, causing a copy-on-write.
But the Guest pagetables still refer to the old page: we fault again,
but as Host we see the hypercall already rewritten, and pass the fault
back to the Guest.  The Guest hasn't set up an IDT yet, so we kill it.

This doesn't happen with bzImages: they unpack themselves and so the
text pages are already read-write.

Subject: lguest: fix guest crash on non-linear addresses in gdt pvops

Fixes guest crash 'lguest: bad read address 0x4800000 len 256'

The new per-cpu allocator ends up handing a non-linear address to
write_gdt_entry.  We do __pa() on it, and hand it to the host, which
kills us.

I've long wanted to make the hypercall "LOAD_GDT_ENTRY" to match the IDT
code, but had no pressing reason until now.

Subject: lguest: document 32-bit and PAE requirements

Robert noted that we don't actually document that lguest is 32-bit only,
nor that PAE must be off (CONFIG_PAE is now prompted for if HIGHMEM is
set to "off).

Subject: [ARM] pxa/palm27x: General fix for Palm27x aSoC driver

Firstly, this patch makes the palm27x asoc driver a little more sane. Also,
since all affected devices use GPIO95 as AC97_nRESET, this patch sets that
properly. Affected are PalmT5, TX and LifeDrive.

Subject: Don't set relatime when noatime is specified

Since commit 0a1c01c9477602ee8b44548a9405b2c1d587b5a2 ("Make relatime
default") when a file system is mounted explicitely with noatime it gets
both the MNT_RELATIME and MNT_NOATIME bits set.

This shows up like this in /proc/mounts:

  /dev/xxx /yyy ext3 rw,noatime,relatime,errors=continue,data=writeback 0 0

That looks strange.  The VFS uses noatime in this case, but both flags
are set.  So it's more a cosmetic issue, but still better to fix.

This reverts commit 1c55f18717304100a5f624c923f7cb6511b4116d.

Ingo Brueckl was assuming that reverting to 1:1 mapping for chars >= 128
was not useful, but it happens to be: due to the limitations of the
Linux console, when a blind user wants to read BIG5 on it, he has no
other way than loading a font without SFM and let the 1:1 mapping permit
the screen reader to get the BIG5 encoding.

Subject: PM/Suspend: Introduce two new platform callbacks to avoid breakage

Commit 900af0d973856d6feb6fc088c2d0d3fde57707d3 (PM: Change suspend
code ordering) changed the ordering of suspend code in such a way
that the platform .prepare() callback is now executed after the
device drivers' late suspend callbacks have run.  Unfortunately, this
turns out to break ARM platforms that need to talk via I2C to power
control devices during the .prepare() callback.

For this reason introduce two new platform suspend callbacks,
.prepare_late() and .wake(), that will be called just prior to
disabling non-boot CPUs and right after bringing them back on line,
respectively, and use them instead of .prepare() and .finish() for
ACPI suspend.  Make the PM core execute the .prepare() and .finish()
platform suspend callbacks where they were executed previously (that
is, right after calling the regular suspend methods provided by
device drivers and right before executing their regular resume
methods, respectively).

It is not necessary to make analogous changes to the hibernation
code and data structures at the moment, because they are only used
by ACPI platforms.

Subject: drm: clean dirty memory after device release

In current code we register/unregister connector object by
drm_sysfs_connector_add/remove function.

However under some cases, we need to dynamically register or unregister device
multiple times, so we have to go through register -> unregister ->register
routine.

Because after device_unregister function our memory is dirty, we need to do
clean operation in order to re-register the device, otherwise the system
will crash.  The patch intends to clean device after device release.

Regression resulted in the below error happened on systems with
software coordination where per_cpu acpi data will not be initiated for
secondary CPUs in a P-state domain.

Subject: acpi-cpufreq: Do not let get_measured perf depend on internal
 variable

Take already available policy->cpuinfo.max_freq and get rid of acpi-cpufreq
specific max_freq variable.

This implies that P0 is always the highest frequency which should always
be true as ACPI spec says:
As a result, the zeroth entry describes the highest performance state

Use it to clean up snd_us122l_card_used[].

Without patch unplugging of an US122L soundcard didn't reset the
corresponding element of snd_us122l_card_used[] to 0.
The (SNDRV_CARDS + 1)th plugging in did not result in creating the soundcard
device anymore.
Index values supplied with the modprobe command line were not used correctly
anymore after the first unplugging of an US122L.

Subject: [ARM] 5456/1: add sys_preadv and sys_pwritev

Kernel 2.6.30-rc1 added sys_preadv and sys_pwritev to most archs
but not ARM, resulting in

<stdin>:1421:2: warning: #warning syscall preadv not implemented
<stdin>:1425:2: warning: #warning syscall pwritev not implemented

This patch adds sys_preadv and sys_pwritev to ARM.

These syscalls simply take five long-sized parameters, so they
should have no calling-convention/ABI issues in the kernel.

Tested on armv5tel eabi using a preadv/pwritev test program posted
on linuxppc-dev earlier this month.

It would be nice to get this into the kernel before 2.6.30 final,
so that glibc's kernel version feature test for these syscalls
doesn't have to special-case ARM.

Subject: driver: dont update dev_name via device_add path

notice one system /proc/iomem some entries missed the name for pci_devices

it turns that dev->dev.kobj name is changed after device_add.

for pci code: via acpi_pci_root_driver.ops.add (aka acpi_pci_root_add)
==> pci_acpi_scan_root is used to scan pci bus/device, and at the same
time we read the resource for pci_dev in the pci_read_bases, we have
res->name = pci_name(pci_dev); pci_name is calling dev_name.

later via acpi_pci_root_driver.ops.start (aka acpi_pci_root_start) ==>
pci_bus_add_device to add all pci_dev in kobj tree.  pci_bus_add_device
will call device_add.

actually in device_add

        /* first, register with generic layer. */
        error = kobject_add(&dev->kobj, dev->kobj.parent, "%s", dev_name(dev));
        if (error)
                goto Error;

will get one new name for that kobj, old name is freed.

Subject: x86/uv: fix for no memory at paddr 0

Fix endcase where the memory at physical address 0 does not really
exist AND one of the sockets on blade 0 has no active cpus.

The memory that _appears_ to be at physical address 0 is actually
memory that located at a different address but has been remapped by
the chipset so that it appears to be at physical address 0.

When determining the UV pnode, the algorithm for determining the pnode
incorrectly used the relocated physical address instead of the actual
(global) address.

[ Impact: boot failure on partitioned systems ]

Subject: [IA64] fix allmodconfig compilation breakage.

This patch fixes the following compilation error caused by recursive
inclusion of kernel.h which defines BUILD_BUG_ON().
In this case, the case it catches will be caught by the case
CONFIG_PARAVIRT=n, so removing it would not hurt compile time check
very much. So fix the breakage by removing it.

Subject: Btrfs: use WRITE_SYNC for synchronous writes

Part of reducing fsync/O_SYNC/O_DIRECT latencies is using WRITE_SYNC for
writes we plan on waiting on in the near future.  This patch
mirrors recent changes in other filesystems and the generic code to
use WRITE_SYNC when WB_SYNC_ALL is passed and to use WRITE_SYNC for
other latency critical writes.

Btrfs uses async worker threads for checksumming before the write is done,
and then again to actually submit the bios.  The bio submission code just
runs a per-device list of bios that need to be sent down the pipe.

This list is split into low priority and high priority lists so the
WRITE_SYNC IO happens first.

Subject: Btrfs: add a priority queue to the async thread helpers

Btrfs is using WRITE_SYNC_PLUG to send down synchronous IOs with a
higher priority.  But, the checksumming helper threads prevent it
from being fully effective.

There are two problems.  First, a big queue of pending checksumming
will delay the synchronous IO behind other lower priority writes.  Second,
the checksumming uses an ordered async work queue.  The ordering makes sure
that IOs are sent to the block layer in the same order they are sent
to the checksumming threads.  Usually this gives us less seeky IO.

But, when we start mixing IO priorities, the lower priority IO can delay
the higher priority IO.

This patch solves both problems by adding a high priority list to the async
helper threads, and a new btrfs_set_work_high_prio(), which is used
to make put a new async work item onto the higher priority list.

The ordering is still done on high priority IO, but all of the high
priority bios are ordered separately from the low priority bios.  This
ordering is purely an IO optimization, it is not involved in data
or metadata integrity.

Subject: Btrfs: fix oops on page->mapping->host during writepage

The extent_io writepage call updates the writepage index in the inode
as it makes progress.  But, it was doing the update after unlocking the page,
which isn't legal because page->mapping can't be trusted once the page
is unlocked.

This lead to an oops, especially common with compression turned on.  The
fix here is to update the writeback index before unlocking the page.

Subject: Btrfs: use the right node in reada_for_balance

reada_for_balance was using the wrong index into the path node array,
so it wasn't reading the right blocks.  We never directly used the
results of the read done by this function because the btree search is
started over at the end.

This fixes reada_for_balance to reada in the correct node and to
avoid searching past the last slot in the node.  It also makes sure to
hold the parent lock while we are finding the nodes to read.

Subject: cifs: Rename cifs_strncpy_to_host and fix buffer size

There is a possibility for the path_name and node_name buffers to
overflow if they contain charcters that are >2 bytes in the local
charset. Resize the buffer allocation so to avoid this possibility.

Also, as pointed out by Jeff Layton, it would be appropriate to
rename the function to cifs_strlcpy_to_host to reflect the fact
that the copied string is always NULL terminated.

Subject: RDMA/cxgb3: Adjust ORD/IRD (if needed) for peer2peer connections

NFS/RDMA currently fails to set up connections if peer2peer is on.
This is due to the fact that the NFS/RDMA client sets its ORD to 0.

If peer2peer is set, make sure the active side ORD is >= 1 and the
passive side IRD is >=1.

Subject: IPoIB: Disable NAPI while CQ is being drained

If NAPI is enabled while IPoIB's CQ is being drained, it creates a
race on priv->ibwc between ipoib_poll() and ipoib_drain_cq(), leading
to memory corruption.

The solution is to enable/disable NAPI in ipoib_ib_dev_{open/stop}()
instead of in ipoib_{open/stop}(), and sync NAPI on the INITIALIZED
flag instead on the ADMIN_UP flag. This way NAPI will be disabled when
ipoib_drain_cq() is called.

This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1587>.

Subject: x86-64: fix FPU corruption with signals and preemption

In 64bit signal delivery path, clear_used_math() was happening before saving
the current active FPU state on to the user stack for signal handling. Between
clear_used_math() and the state store on to the user stack, potentially we
can get a page fault for the user address and can block. Infact, while testing
we were hitting the might_fault() in __clear_user() which can do a schedule().

At a later point in time, we will schedule back into this process and
resume the save state (using "xsave/fxsave" instruction) which can lead
to DNA fault. And as used_math was cleared before, we will reinit the FP state
in the DNA fault and continue. This reinit will result in loosing the
FPU state of the process.

Move clear_used_math() to a point after the FPU state has been stored
onto the user stack.

This issue is present from a long time (even before the xsave changes
and the x86 merge). But it can easily be exposed in 2.6.28.x and 2.6.29.x
series because of the __clear_user() in this path, which has an explicit
__cond_resched() leading to a context switch with CONFIG_PREEMPT_VOLUNTARY.

Subject: RDMA/nes: Fix bugs in nes_reg_phys_mr()

The code incorrectly failed memory registration if the buffer was not
page aligned.  Also, the length field is mangled causing the hardware
to think the registration is much larger than it really is.

The fix is to remove the page alignment restriction as well the
incorrect length adjustment.  Also make sure that all buffers after
the first start at a page boundary, and all buffers except the last
end on a page boundary.

mmap2 uses a fixed page shift of 12, regardless of the PAGE_SIZE setting.
Fix up the mmap2 code to add some sanity checks on the mapping, and to
update pgoff accordingly.

Error handling bits based on 4280e3126f641898f0ed1a931645373d3489e2a6
("frv: fix mmap2 error handling").

Subject: RDMA/cxgb3: Don't zero QP attrs when moving to IDLE

QP attributes must stay initialized when moving back to IDLE.  Zeroing
them will crash the system in _flush_qp() if the QP is subsequently
moved to ERROR and back to IDLE.

Subject: Safer nfsd_cross_mnt()

AFAICS, we have a subtle bug there: if we have crossed mountpoint
*and* it got mount --move'd away, we'll be holding only one
reference to fs containing dentry - exp->ex_path.mnt.  IOW, we
ought to dput() before exp_put().

Subject: Fix i_mutex vs. readdir handling in nfsd

Commit 14f7dd63 ("Copy XFS readdir hack into nfsd code") introduced a
bug to generic code which had been extant for a long time in the XFS
version -- it started to call through into lookup_one_len() and hence
into the file systems' ->lookup() methods without i_mutex held on the
directory.

This patch fixes it by locking the directory's i_mutex again before
calling the filldir functions. The original deadlocks which commit
14f7dd63 was designed to avoid are still avoided, because they were due
to fs-internal locking, not i_mutex.

While we're at it, fix the return type of nfsd_buffered_readdir() which
should be a __be32 not an int -- it's an NFS errno, not a Linux errno.
And return nfserrno(-ENOMEM) when allocation fails, not just -ENOMEM.
Sparse would have caught that, if it wasn't so busy bitching about
__cold__.

Commit 05f4f678 ("nfsd4: don't do lookup within readdir in recovery
code") introduced a similar problem with calling lookup_one_len()
without i_mutex, which this patch also addresses. To fix that, it was
necessary to fix the called functions so that they expect i_mutex to be
held; that part was done by J. Bruce Fields.

Subject: Documentation/filesystems: remove out of date reference to BKL being
 held

Documentation/filesystems/vfs.txt incorrectly states that the kernel is
locked during the call to statfs (Documentation/filesystems/Locking
correctly says it is not). This patch removes the offending sentence.

remove reference to BKL being held in statfs

Subject: btrfs: use memdup_user()

Remove open-coded memdup_user().

Note this changes some GFP_NOFS to GFP_KERNEL, since copy_from_user() may
cause pagefault, it's pointless to pass GFP_NOFS to kmalloc().

Subject: kill vfs_stat_fd / vfs_lstat_fd

There's really no reason to keep vfs_stat_fd and vfs_lstat_fd with
Oleg's vfs_fstatat.  Use vfs_fstatat for the few cases having the
directory fd, and switch all others to vfs_stat / vfs_lstat.

Subject: IB/mthca: Fix timeout for INIT_HCA and a few other commands

Commands INIT_HCA, CLOSE_HCA, SYS_EN, SYS_DIS, and CLOSE_IB all have 1
second timeouts.  For INIT_HCA this causes problems when had more than
2^18 are QPs configured, since the command takes more than 1 second to
complete.

All other commands have 60-second timeouts.  This patch makes the
above commands consistent with the rest of the commands (and with the
chip documentation).

This patch is an expansion of a patch from Arthur Kepner
<akepner@sgi.com> fixing just the INIT_HCA timeout.

Subject: x86: fix boot crash in NMI watchdog with CONFIG_CPUMASK_OFFSTACK=y
 and flat APIC

fcef8576d8a64fc603e719c97d423f9f6d4e0e8b converted backtrace_mask to a
cpumask_var_t, and assumed check_nmi_watchdog was called before
nmi_watchdog_tick was ever called.  Steven's oops shows I was wrong.

This is something of a bandaid: I'm not sure we *should* be calling
nmi_watchdog_tick before check_nmi_watchdog.  Note that gcc eliminates
this test for the CONFIG_CPUMASK_OFFSTACK=n case.

Subject: x86: avoid theoretical spurious NMI backtraces with
 CONFIG_CPUMASK_OFFSTACK=y

In theory (though not shown in practice) alloc_cpumask_var() doesn't zero
memory, so CPUs might print an "NMI backtrace for cpu %d" once on boot.

(Bug introduced in fcef8576d8a64fc603e719c97d423f9f6d4e0e8b).

-Creation of the self-extracting compressed kernel image (vmlinuz)
------------------------------------------------------------------
-$Id: README,v 1.1 2001/12/17 13:59:27 bjornw Exp $
-
-This can be slightly confusing because it's a process with many steps.
-
-The kernel object built by the arch/etrax100/Makefile, vmlinux, is split
-by that makefile into text and data binary files, vmlinux.text and 
-vmlinux.data.
-
-Those files together with a ROM filesystem can be catted together and
-burned into a flash or executed directly at the DRAM origin.
-
-They can also be catted together and compressed with gzip, which is what
-happens in this makefile. Together they make up piggy.img. 
-
-The decompressor is built into the file decompress.o. It is turned into
-the binary file decompress.bin, which is catted together with piggy.img
-into the file vmlinuz. It can be executed in an arbitrary place in flash.
-
-Be careful - it assumes some things about free locations in DRAM. It
-assumes the DRAM starts at 0x40000000 and that it is at least 8 MB,
-so it puts its code at 0x40700000, and initial stack at 0x40800000.

-/*
- * Rescue code, made to reside at the beginning of the
- * flash-memory. when it starts, it checks a partition
- * table at the first sector after the rescue sector.
- * the partition table was generated by the product builder
- * script and contains offsets, lengths, types and checksums
- * for each partition that this code should check.
- *
- * If any of the checksums fail, we assume the flash is so
- * corrupt that we cant use it to boot into the ftp flash
- * loader, and instead we initialize the serial port to
- * receive a flash-loader and new flash image. we dont include
- * any flash code here, but just accept a certain amount of
- * bytes from the serial port and jump into it. the downloaded
- * code is put in the cache.
- *
- * The partitiontable is designed so that it is transparent to
- * code execution - it has a relative branch opcode in the
- * beginning that jumps over it. each entry contains extra
- * data so we can add stuff later.
- *
- * Partition table format:
- *
- *     Code transparency:
- *
- *     2 bytes    [opcode 'nop']
- *     2 bytes    [opcode 'di']
- *     4 bytes    [opcode 'ba <offset>', 8-bit or 16-bit version]
- *     2 bytes    [opcode 'nop', delay slot]
- *
- *     Table validation (at +10):
- *
- *     2 bytes    [magic/version word for partitiontable - 0xef, 0xbe]
- *     2 bytes    [length of all entries plus the end marker]
- *     4 bytes    [checksum for the partitiontable itself]
- *
- *     Entries, each with the following format, last has offset -1:
- *
- *        4 bytes    [offset in bytes, from start of flash]
- *        4 bytes    [length in bytes of partition]
- *        4 bytes    [checksum, simple longword sum]
- *        2 bytes    [partition type]
- *        2 bytes    [flags, only bit 0 used, ro/rw = 1/0]
- *        16 bytes   [reserved for future use]
- *
- *     End marker
- *
- *        4 bytes    [-1]
- *
- *	 10 bytes    [0, padding]
- *
- * Bit 0 in flags signifies RW or RO. The rescue code only bothers
- * to check the checksum for RO partitions, since the others will
- * change their data without updating the checksums. A 1 in bit 0
- * means RO, 0 means RW. That way, it is possible to set a partition
- * in RO mode initially, and later mark it as RW, since you can always
- * write 0's to the flash.
- *
- * During the wait for serial input, the status LED will flash so the
- * user knows something went wrong.

-Creation of the self-extracting compressed kernel image (vmlinuz)
------------------------------------------------------------------
-
-This can be slightly confusing because it's a process with many steps.
-
-The kernel object built by the arch/etrax100/Makefile, vmlinux, is split
-by that makefile into text and data binary files, vmlinux.text and
-vmlinux.data.
-
-Those files together with a ROM filesystem can be catted together and
-burned into a flash or executed directly at the DRAM origin.
-
-They can also be catted together and compressed with gzip, which is what
-happens in this makefile. Together they make up piggy.img.
-
-The decompressor is built into the file decompress.o. It is turned into
-the binary file decompress.bin, which is catted together with piggy.img
-into the file vmlinuz. It can be executed in an arbitrary place in flash.
-
-Be careful - it assumes some things about free locations in DRAM. It
-assumes the DRAM starts at 0x40000000 and that it is at least 8 MB,
-so it puts its code at 0x40700000, and initial stack at 0x40800000.

+Creation of the self-extracting compressed kernel image (vmlinuz)
+-----------------------------------------------------------------
+
+This can be slightly confusing because it's a process with many steps.
+
+The kernel object built by the arch/etrax100/Makefile, vmlinux, is split
+by that makefile into text and data binary files, vmlinux.text and
+vmlinux.data.
+
+Those files together with a ROM filesystem can be catted together and
+burned into a flash or executed directly at the DRAM origin.
+
+They can also be catted together and compressed with gzip, which is what
+happens in this makefile. Together they make up piggy.img.
+
+The decompressor is built into the file decompress.o. It is turned into
+the binary file decompress.bin, which is catted together with piggy.img
+into the file vmlinuz. It can be executed in an arbitrary place in flash.
+
+Be careful - it assumes some things about free locations in DRAM. It
+assumes the DRAM starts at 0x40000000 and that it is at least 8 MB,
+so it puts its code at 0x40700000, and initial stack at 0x40800000.

+ * Rescue code, made to reside at the beginning of the

+ * the partition table was generated by the product builder
+ * script and contains offsets, lengths, types and checksums
+ * for each partition that this code should check.
+ *
+ * If any of the checksums fail, we assume the flash is so
+ * corrupt that we cant use it to boot into the ftp flash
+ * loader, and instead we initialize the serial port to
+ * receive a flash-loader and new flash image. we dont include
+ * any flash code here, but just accept a certain amount of
+ * bytes from the serial port and jump into it. the downloaded
+ * code is put in the cache.
+ *
+ * The partitiontable is designed so that it is transparent to
+ * code execution - it has a relative branch opcode in the
+ * beginning that jumps over it. each entry contains extra
+ * data so we can add stuff later.
+ *
+ * Partition table format:
+ *
+ *     Code transparency:
+ *
+ *     2 bytes    [opcode 'nop']
+ *     2 bytes    [opcode 'di']
+ *     4 bytes    [opcode 'ba <offset>', 8-bit or 16-bit version]
+ *     2 bytes    [opcode 'nop', delay slot]
+ *
+ *     Table validation (at +10):
+ *
+ *     2 bytes    [magic/version word for partitiontable - 0xef, 0xbe]
+ *     2 bytes    [length of all entries plus the end marker]
+ *     4 bytes    [checksum for the partitiontable itself]
+ *
+ *     Entries, each with the following format, last has offset -1:
+ *

Commit ae46141ff08f1965b17c531b571953c39ce8b9e2 (NFSv3: Fix posix ACL code)
introduces a bug in the calculation of the XDR header iovec. In the case
where we are inlining the acls, we need to adjust the length of the iovec
req->rq_svec, in addition to adjusting the total buffer length.

Subject: Btrfs: fix btrfs fallocate oops and deadlock

Btrfs fallocate was incorrectly starting a transaction with a lock held
on the extent_io tree for the file, which could deadlock.  Strictly
speaking it was using join_transaction which would be safe, but it is better
to move the transaction outside of the lock.

When preallocated extents are overwritten, btrfs_mark_buffer_dirty was
being called on an unlocked buffer.  This was triggering an assertion and
oops because the lock is supposed to be held.

The bug was calling btrfs_mark_buffer_dirty on a leaf after btrfs_del_item had
been run.  btrfs_del_item takes care of dirtying things, so the solution is a
to skip the btrfs_mark_buffer_dirty call in this case.

When the msi_x option is enabled but pci_enable_msix() fails (not
enough vectors are available etc), the entries array was not freed on

Subject: go7007: Convert to the new i2c device binding model

Move the go7007 driver away from the legacy i2c binding model, which
is going away really soon now.

The I2C addresses of the audio and video chips in s2250-board didn't
look quite right, apparently they were left-aligned values when Linux
wants right-aligned values, so I fixed them too.

I observed the following build warning with fs/configfs/symlink.c:

fs/configfs/symlink.c: In function 'configfs_symlink':
fs/configfs/symlink.c:138: warning: 'target_item' may be used uninitialized in this function

Here is a small fix for this.

Subject: powerpc: don't disable SATA interrupts on Freescale MPC8610 HPCD

The ULI 1575 PCI quirk function for the Freescale MPC8610 HPCD was disabling
the SATA INTx interrupt, even when SATA support was enabled.  This was safe,
because the SATA driver re-enabled it.  But with commit a5bfc471 ("ahci: drop
intx manipulation on msi enable"), the driver no longer does this, and so SATA
support on the 8610 HPCD is broken.

The original quirk function disabled INTx because it caused some other
interrupt problem during early development on this board, but no one remembers
any more what that problem was, and it doesn't seem to occur any more.

Subject: clocksource: add enable() and disable() callbacks

Add enable() and disable() callbacks for clocksources.

This allows us to put unused clocksources in power save mode.  The
functions clocksource_enable() and clocksource_disable() wrap the
callbacks and are inserted in the timekeeping code to enable before use
and disable after switching to a new clocksource.

Subject: ipmi: test for event buffer before using

The IPMI driver would attempt to use the event buffer even if that
didn't exist on the BMC.  This patch modified the IPMI driver to check
for the event buffer's existence before trying to use it.

Subject: ipmi: fix statistics counting issues

Bela Lubkin noticed that the statistics for send IPMB and LAN commands
in the IPMI driver could be incremented even if an error occurred.  Move
the increments to the proper place to avoid this.

Also add some statistics for retransmissions that failed, and some little
helper functions to neaten up the code a little.

Subject: drivers/input/serio/hp_sdc.c: fix crash when removing hp_sdc module

On parisc machines, which don't have HIL, removing the hp_sdc module
panics the kernel.  Fix this by returning early in hp_sdc_exit() if no HP
SDC controller was found.

Add functionality to probe for the hp_sdc_mlc kernel module (which takes
care of the upper layer HIL functionality on parisc) after two seconds.
This is needed to get all the other HIL drivers (keyboard / mouse/ ..)
drivers automatically loaded by udev later as well.

Subject: spi: pxa2xx: limit reaches -1

On line 944 the return value of flush() is considered as a boolean,
but limit reaches -1 upon timeout which evaluates to true.

On 540, 594, 720 the same occurs for wait_ssp_rx_stall()
On 536 the same occurs for wait_dma_channel_stop()

Subject: spi: documentation: emphasise spi_master.setup() semantics

This is a doc-only patch which I hope will reduce the number of
spi_master controller driver patches starting out with a common
implementation bug.

(As in: almost every spi_master driver I see starts out with its
version of this bug.  Sigh.)

It just re-emphasizes that the setup() method may be called for one
device while a transfer is active on another ...  which means that most
driver implementations shouldn't touch any registers.

Subject: frv: insert PCI root bus resources for the MB93090 devel motherboard

Insert PCI root bus resources for the FRV-based MB93090 development kit
motherboard.  This is required because the CPU's window onto the PCI bus
address space is considerably smaller than the CPU's full address space
and non-PCI devices lie outside of the PCI window that we might want to
access.

Without this patch, the PCI root bus uses the platform-level bus
resources, and these are then confined to the PCI window, thus making
platform_device_add() reject devices outside of this window.

Noticing that every caller of mpt_config has its CONFIGPARMS struct
declared on the stack and thus the &pCfg->timer is always on the stack I
changed init_timer() to init_timer_on_stack() and it seems to have shut
up.....

Subject: edac: ppc mpc85xx fix mc err detect

Error found by Jeff Haran.

The error detect register is 0s when no errors are detected.  The check
code is incorrect, so reverse check sense.

Subject: vmscan,memcg: reintroduce sc->may_swap

Commit a6dc60f8975ad96d162915e07703a4439c80dcf0 ("vmscan: rename
sc.may_swap to may_unmap") removed the may_swap flag, but memcg had used
it as a flag for "we need to use swap?", as the name indicate.

And in the current implementation, memcg cannot reclaim mapped file
caches when mem+swap hits the limit.

re-introduce may_swap flag and handle it at get_scan_ratio().  This
patch doesn't influence any scan_control users other than memcg.

From 3de0e075486cc1a175d63bb7167bfc66e9ac16f4 Mon Sep 17 00:00:00 2001
From: Kumar Gala

Subject: powerpc/85xx: Added SMP defconfig

Since the vast majority of 85xx platforms are UP we introduce a new SMP
config for the few platforms that have more than one core.  Beyond
CONFIG_SMP=y and its dependencies this should be identical to
mpc85xx_defconfig.

Subject: RDMA/nes: Fix resource issues in nes_create_cq() and nes_destroy_cq()

In error paths where a CQ is not created, pbl is not freeed properly.

In nes_destroy_cq(), add the corresponding check for nescq->mcrqf to
not call nes_free_resource() when it is already done in nes_create_cq().

Subject: drm/i915: add support for G41 chipset

This had been delayed for some time due to failure to work on the one piece
of G41 hardware we had, and lack of success reports from anybody else.
Current hardware appears to be OK.

Subject: x86: more than 8 32-bit CPUs requires X86_BIGSMP

$ cat x86-more-than-8-cpus-requires-bigsmp.patch

Enforce NR_CPUS <= 8 limitation if X86_BIGSMP not set

Configuring more than 8 logical CPUs on 32-bit x86 requires
X86_BIGSMP to be set in order to boot successfully, if more than 8
logical CPUs are actually found at boot time.  The X86_BIGSMP help
text describes that it is required to be set if more than 8 CPUs
are configured, but this was previously not enforced.

This configuration error has affected multiple distributions:

Subject: FRV: Fix the section attribute on UP DECLARE_PER_CPU()

In non-SMP mode, the variable section attribute specified by DECLARE_PER_CPU()
does not agree with that specified by DEFINE_PER_CPU().  This means that
architectures that have a small data section references relative to a base
register may throw up linkage errors due to too great a displacement between
where the base register points and the per-CPU variable.

On FRV, the .h declaration says that the variable is in the .sdata section, but
the .c definition says it's actually in the .data section.  The linker throws
up the following errors:

kernel/built-in.o: In function `release_task':
kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o
kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o

To fix this, DECLARE_PER_CPU() should simply apply the same section attribute
as does DEFINE_PER_CPU().  However, this is made slightly more complex by
virtue of the fact that there are several variants on DEFINE, so these need to
be matched by variants on DECLARE.

Subject: PERCPU: Collect the DECLARE/DEFINE declarations together

Collect the DECLARE/DEFINE declarations together in linux/percpu-defs.h so
that they're in one place, and give them descriptive comments, particularly
the SHARED_ALIGNED variant.

It would be nice to collect these in linux/percpu.h, but that's not possible
without sorting out the severe #include recursion between the x86 arch headers
and the general headers (and possibly other arches too).

Subject: driver synchronization: make scsi_wait_scan more advanced

There is currently only one way for userspace to say "wait for my storage
device to get ready for the modules I just loaded": to load the
scsi_wait_scan module. Expectations of userspace are that once this
module is loaded, all the (storage) devices for which the drivers
were loaded before the module load are present.

Now, there are some issues with the implementation, and the async
stuff got caught in the middle of this: The existing code only
waits for the scsy async probing to finish, but it did not take
into account at all that probing might not have begun yet.
(Russell ran into this problem on his computer and the fix works for him)

This patch fixes this more thoroughly than the previous "fix", which
had some bad side effects (namely, for kernel code that wanted to wait for
the scsi scan it would also do an async sync, which would deadlock if you did
it from async context already.. there's a report about that on lkml):
The patch makes the module first wait for all device driver probes, and then it
will wait for the scsi parallel scan to finish.

This processor only have one FEC and its MDIO pins are
located at a different offset than the code used for
the current CONFIG_M527x.

Tesed on M5271EVB eval platform.
Without this patch the FEC driver will report no PHY attached
if the bootloader does not pre-initialize the PAR_FECI2C GPIO register.

Now that ppc32 implements address randomization it also wants to inherit
personality flags like ADDR_NO_RANDOMIZE across exec, for things like
`setarch ppc -R' to work.  But the ppc32 version of SET_PERSONALITY
forcefully sets PER_LINUX, clearing all personality flags.  So be
careful about preserving the flags.

Subject: powerpc: Fix modular build of ide-pmac when mediabay is built in

Now that the powermac IDE host driver can be modular, we need to
export check_media_bay_by_base() and media_bay_set_ide_infos()
from drivers/macintosh/mediabay.c for it.

This fixes the following build error:

Subject: scatterlist: make sure sg_miter_next() doesn't return 0 sized
 mappings

Impact: fix not-so-critical but annoying bug

sg_miter_next() returns 0 sized mapping if there is an zero sized sg
entry in the list or at the end of each iteration.  As the users
always check the ->length field, this bug shouldn't be critical other
than causing unnecessary iteration.

Fix it.

Subject: block: fix SG_IO vector request data length handling

Impact: fix SG_IO behavior such that it matches the documentation

SG_IO howto says that if ->dxfer_len and sum of iovec disagress, the
shorter one wins.  However, the current implementation returns -EINVAL
for such cases.  Trim iovc if it's longer than ->dxfer_len.

This patch uses iov_*() helpers which take struct iovec * by casting
struct sg_iovec * to it.  sg_iovec is always identical to iovec and
this will be further cleaned up with later patches.

Subject: block: fix queue bounce limit setting

Impact: don't set GFP_DMA in q->bounce_gfp unnecessarily

All DMA address limits are expressed in terms of the last addressable
unit (byte or page) instead of one plus that.  However, when
determining bounce_gfp for 64bit machines in blk_queue_bounce_limit(),
it compares the specified limit against 0x100000000UL to determine
whether it's below 4G ending up falsely setting GFP_DMA in
q->bounce_gfp.

As DMA zone is very small on x86_64, this makes larger SG_IO transfers
very eager to trigger OOM killer.  Fix it.  While at it, rename the
parameter to @dma_mask for clarity and convert comment to proper
winged style.

Subject: bio: fix bio_kmalloc()

Impact: fix bio_kmalloc() and its destruction path

bio_kmalloc() was broken in two ways.

* bvec_alloc_bs() first allocates bvec using kmalloc() and then
  ignores it and allocates again like non-kmalloc bvecs.

* bio_kmalloc_destructor() didn't check for and free bio integrity
  data.

This patch fixes the above problems.  kmalloc patch is separated out
from bio_alloc_bioset() and allocates the requested number of bvecs as
inline bvecs.

* bio_alloc_bioset() no longer takes NULL @bs.  None other than
  bio_kmalloc() used it and outside users can't know how it was
  allocated anyway.

* Define and use BIO_POOL_NONE so that pool index check in
  bvec_free_bs() triggers if inline or kmalloc allocated bvec gets
  there.

* Relocate destructors on top of each allocation function so that how
  they're used is more clear.

Jens Axboe suggested allocating bvecs inline.

Subject: bio: use bio_kmalloc() in copy/map functions

Impact: remove possible deadlock condition

There is no reason to use mempool backed allocation for map functions.
Also, because kern mapping is used inside LLDs (e.g. for EH), using
mempool backed allocation can lead to deadlock under extreme
conditions (mempool already consumed by the time a request reached EH
and requests are blocked on EH).

Switch copy/map functions to bio_kmalloc().

zero-sized or not and their non-zero partitions.  Commit
074a7aca7afa6f230104e8e65eba3420263714a5 accidentally changed the
behavior such that it doesn't print out zero sized disks.  This patch
implements DISK_PITER_INCL_EMPTY_PART0 flag to partition iterator and
uses it in diskstats_show() such that empty part0 is shown in
/proc/diskstats.

Subject: block: make blk_abort_queue() ignore non-request based devices

There's nothing to do for those devices, since the timeout handling is
based on requests.

Subject: cfq-iosched: make seek_mean converge more quickly

Right now, depending on the first sector to which a process issues I/O,
the seek time may start out way out of whack. So make sure we start
with 0 sectors in seek, instead of the offset of the first request
issued.

Subject: cfq-iosched: use the default seek distance when there aren't enough
 seek samples

If the cfq io context doesn't have enough samples yet to provide a mean
seek distance, then use the default threshold we have for seeky IO instead
of defaulting to 0.

Subject: eCryptfs: Copy lower inode attrs before dentry instantiation

Copies the lower inode attributes to the upper inode before passing the
upper inode to d_instantiate().  This is important for
security_d_instantiate().

The problem was discovered by a user seeing SELinux denials like so:

type=AVC msg=audit(1236812817.898:47): avc:  denied  { 0x100000 } for
pid=3584 comm="httpd" name="testdir" dev=ecryptfs ino=943872
scontext=root:system_r:httpd_t:s0
tcontext=root:object_r:httpd_sys_content_t:s0 tclass=file

Notice target class is file while testdir is really a directory,
confusing the permission translation (0x100000) due to the wrong i_mode.

afterwards.  ecryptfs_send_raw_message() is the only place that
ecryptfs_send_miscdev() is called with data being NULL, but the only
caller of that function (ecryptfs_process_helo()) is never called.  In
short, there is currently no way to trigger the NULL pointer
dereference.

This patch removes the two unused functions and modifies
ecryptfs_send_miscdev() to remove the NULL dereferences.

Subject: eCryptfs: Print FNEK sig properly in /proc/mounts

The filename encryption key signature is not properly displayed in
/proc/mounts.  The "ecryptfs_sig=" mount option name is displayed for
all global authentication tokens, included those for filename keys.

This patch checks the global authentication token flags to determine if
the key is a FEKEK or FNEK and prints the appropriate mount option name
before the signature.

Subject: eCryptfs: Fix data corruption when using ecryptfs_passthrough

ecryptfs_passthrough is a mount option that allows eCryptfs to allow
data to be written to non-eCryptfs files in the lower filesystem.  The
passthrough option was causing data corruption due to it not always
being treated as a non-eCryptfs file.

The first 8 bytes of an eCryptfs file contains the decrypted file size.
This value was being written to the non-eCryptfs files, too.  Also,
extra 0x00 characters were being written to make the file size a
multiple of PAGE_CACHE_SIZE.

Subject: eCryptfs: Remove ecryptfs_unlink_sigs warnings

A feature was added to the eCryptfs umount helper to automatically
unlink the keys used for an eCryptfs mount from the kernel keyring upon
umount.  This patch keeps the unrecognized mount option warnings for
ecryptfs_unlink_sigs out of the logs.

Subject: sparc: Fix bus type probing for ESP and LE devices.

If there is a dummy "espdma" or "ledma" parent device above ESP scsi
or LE ethernet device nodes, we have to match the bus as SBUS.

Otherwise the address and size cell counts are wrong and we don't
calculate the final physical device resource values correctly at all.

Commit 5280267c1dddb8d413595b87dc406624bb497946 ("sparc: Fix handling
of LANCE and ESP parent nodes in of_device.c") was meant to fix this
problem, but that only influences the inner loop of
build_device_resources().  We need this logic to also kick in at the
beginning of build_device_resources() as well, when we make the first
attempt to determine the device's immediate parent bus type for 'reg'
property element extraction.

Based almost entirely upon a patch by Friedrich Oslage.

Subject: KVM: MMU: Fix off-by-one calculating large page count

The large page initialization code concludes there are two large pages spanned
by a slot covering 1 (small) page starting at gfn 1.  This is incorrect, and
also results in incorrect write_count initialization in some cases (base = 1,
npages = 513 for example).

Subject: KVM: ia64: fix locking order entering guest

Reorder locking as down_read() may return with local interrupts enabled,
which means we could go into vti_vcpu_run() with interrupts enabled.

This caused random crashes on the Altix as the timer interrupt tried
to read a memory mapped clock source, for which the TLB had not yet been
reinstated in the exit, before ipsr was retored.

Subject: KVM: Fix overlapping check for memory slots

When checking for overlapping slots on registration of a new one, kvm
currently also considers zero-length (ie. deleted) slots and rejects
requests incorrectly. This finally denies user space from joining slots.
Fix the check by skipping deleted slots and advertise this via a
KVM_CAP_JOIN_MEMORY_REGIONS_WORKS.

Subject: x86: hpet: fix periodic mode programming on AMD 81xx

(See http://bugzilla.kernel.org/show_bug.cgi?id=12961)

It partially reverts commit c23e253e67c9d8a91a0ffa33c1f571a17f0a2403
(x86: hpet: stop HPET_COUNTER when programming periodic mode)

HPET on AMD 81xx chipset needs a second write (with HPET_TN_SETVAL
cleared) to T0_CMP register to set the period in periodic mode.

With this patch HPET_COUNTER is still stopped but not reset when HPET
is programmed in periodic mode. This should help to avoid races when
HPET is programmed in periodic mode and fixes a boot time hang that
I've observed on a machine when using 1000HZ.

[ Impact: fix boot time hang on machines with AMD 81xx chipset ]

From c5428e950ad42640f00092949fd17e356dfdeafa Mon Sep 17 00:00:00 2001
From: Coly Li
Date: Wed, 22 Apr 2009 23:21:56 +0800
Subject: uv_time: add parameter to uv_read_rtc()

uv_read_rtc() is referenced by read member of struct clocksource clocksource_uv.
In include/linux/clocksource.h, read of struct clocksource is declared as:
cycle_t (*read)(struct clocksource *cs)

This got introduced recently in:

   8e19608: clocksource: pass clocksource to read() callback

But arch/x86/kernel/uv_time.c was not properly converted by that pach.

This patch adds a dummy parameter (struct clocksource type) to uv_read_rtc() to
fix the incompatible reference in clocksource_uv, and add a NULL parameter in
all places where uv_read_rtc() gets called.

[ Impact: cleanup, address compiler warning ]

Subject: palm_bk3710: UDMA performance fix

Fix UDMA throughput bug:  tCYC averages t2CYCTYP/2, but the code
previously assumed it was the same as t2CYCTYP.  (That is, it was
using just one clock edge, not both.)  Move the table's type
declaration so it's adjacent to the table, making it more clear
what those numbers mean.

On one system this change increased throughput by almost 4x: UDMA/66
sometimes topped 23 MB/sec (on a drive known to do much better).  On
another system it was around a 10% win (UDMA/66 up to 7+ MB/sec).

The difference might be caused by the ratio between memory and IDE
clocks.  In the system with large speedup, this was exactly 2 (as a
workaround for a rev 1.1 silicon bug).  The other system used a more
standard ratio of 1.63 (and rev 2.1 silicon) ... clock domain synch
might have some issues, they're not unheard-of.

Subject: ide-cd: fix kernel crash on hppa regression

With 2.6.30-rc2 I face a kernel crash on the 32bit hppa architecture 
due to ide-cd when udev creates the device nodes at startup:

This crash seems to happen due to an uninitialized variable "rc".
The compiler even warns about that:

After applying the trivial patch below, which just initializes 
the variable to zero, the kernel doesn't crash any longer:

mediabay shouldn't include <linux/ide.h> unconditionally so
remove the superfluous include from mediabay.c (<asm/mediabay.h>
will pull <linux/ide.h> in for CONFIG_BLK_DEV_IDE_PMAC=y).

Subject: PCI quirk: disable MSI on VIA VT3364 chipsets

Without this patch, Broadcom BCM5906 Ethernet controllers set up via MSI
cause the machine to hang.  Tejun agreed that the best is to blacklist
the whole chipset and after adding it, seeing the other VIA quirks
disabling MSI, this very much looks like the right way.

Subject: x86, mce: make polling timer interval per CPU

The polling timer while running per CPU still uses a global next_interval
variable, which lead to some CPUs either polling too fast or too slow.   
This was not a serious problem because all errors get picked up eventually,
but it's still better to avoid it. Turn next_interval into a per cpu variable.

v2: Fix check_interval == 0 case (Hidetoshi Seto)

Subject: x86, mce: fix boot logging logic

The earlier patch to change the poller to a separate function subtly
broke the boot logging logic. This could lead to machine checks
getting logged at boot even when disabled or defaulting to off
on some systems. Fix that.

[ Impact: bug fix - avoid spurious MCE in log ]

Subject: x86/PCI: Move set_pci_bus_resources_arch_default into arch/x86

Commit 30a18d6c3f1e774de656ebd8ff219d53e2ba4029 introduced a new
function to set the PCI bus resources.  Unfortunately, neither the
author, nor the committers seemed to know that we already have somewhere
to do that -- pcibios_fixup_bus().  This patch moves the hook (used only
by the K8 code) into x86-specific code where it should have been in the
first place.

Subject: eCryptfs: Lock lower directory inode mutex during lookup

This patch locks the lower directory inode's i_mutex before calling
lookup_one_len() to find the appropriate dentry in the lower filesystem.
This bug was found thanks to the warning set in commit 2f9092e1.

Subject: eCryptfs: Larger buffer for encrypted symlink targets

When using filename encryption with eCryptfs, the value of the symlink
in the lower filesystem is encrypted and stored as a Tag 70 packet.
This results in a longer symlink target than if the target value wasn't
encrypted.

Users were reporting these messages in their syslog:

[ 45.653441] ecryptfs_parse_tag_70_packet: max_packet_size is [56]; real
packet size is [51]
[ 45.653444] ecryptfs_decode_and_decrypt_filename: Could not parse tag
70 packet from filename; copying through filename as-is

This was due to bufsiz, one the arguments in readlink(), being used to
when allocating the buffer passed to the lower inode's readlink().
That symlink target may be very large, but when decoded and decrypted,
could end up being smaller than bufsize.

To fix this, the buffer passed to the lower inode's readlink() will
always be PATH_MAX in size when filename encryption is enabled.  Any
necessary truncation occurs after the decoding and decrypting.

Subject: PCI: only save/restore existent registers in the PCIe capability

PCIe 1.1 base neither requires the endpoint to implement the entire
PCIe capability structure nor specifies default values of registers
that are not implemented by the device. So we only save and restore
registers that must be implemented by different device types if the
device PCIe capability version is 1.

PCIe 1.1 Capability Structure Expansion ECN and PCIe 2.0 requires
all registers in the PCIe capability to be either implemented or
hardwired to 0. Their PCIe capability version is 2.

Subject: ACPI: idle: mark_tsc_unstable() at init-time, not run-time

The c2 and c3 idle handlers check tsc_halts_in_c()
after every time they return from idle.  Um, when?:-)

Move this check to init-time to remove the unnecessary
run-time overhead, and also to have the check complete before
the first entry into the idle handler.

ff69f2bba67bd45514923aaedbf40fe351787c59
(acpi: fix of pmtimer overflow that make Cx states time incorrect)
replaced the hard-coded use of the PM-timer inside idle,
with ktime_get_readl(), which possibly uses the TSC --
so it is now especially prudent to detect a broken TSC
before entering idle.

Subject: ACPI: delete obsolete "bus master activity" proc field

Linux-2.6.29 deleted the legacy ACPI idle handler, leaving
the CPU_IDLE handler, which does not track bus master activity.

So delete the unused bm_activity field -- it is confusing to
print an always zero value.

This patch could break programs that parse
/proc/acpi/processor/*/power, since it deletes this
line from that file:

bus master activity:     00000000

http://bugzilla.kernel.org/show_bug.cgi?id=13145
is not fixed by this patch, but provoked this patch.

Subject: ext4: Make the extent validity check more paranoid

Instead of just checking that the extent block number is greater or
equal than s_first_data_block, make sure it it is not pointing into
the block group descriptors, since that is clearly wrong.  This helps
prevent filesystem from getting very badly corrupted in case an extent
block is corrupted.

Commit 3f0a820c4c0b4670fb5f164baa5582e23c2ef118 breaks OMAP2xxx boot

Subject: ALSA: hda - Fix init verbs of AD1884A mobile model

The current ad1884a-mobile model has a problem that the speaker output
doesn't work sometimes after boot or power-saving on some HP laptops.
It seems that the verbs accessing to the non-functional widgets cause
this problem.

This patch simplifies the init verbs for mobile model not to touch
unnecessary setups so that it avoids the speaker-mute problem.

That commit makes node_possible include cpu nodes that do not have memory.
So check boundary in setup_node_bootmem().

Subject: GFS2: Fix bug in block allocation

The new bitfit algorithm was counting from the wrong end of
64 bit words in the bitfield. This fixes it by using __ffs64
instead of fls64

Subject: GFS2: Ensure that the inode goal block settings are updated

GFS2 has a goal block associated with each inode indicating the
search start position for future block allocations (in fact there
are two, but thats for backward compatibility with GFS1 as they
are set to identical locations in GFS2).

In some circumstances, depending on the ordering of updates to
the inode it was possible for the goal block settings to not
be updated on disk. This patch ensures that the goal block will
always get updated, thus reducing the potential for searching
the same (already allocated) blocks again when looking for free
space during block allocation.

Subject: [S390] appldata: avoid deadlock with appldata_mem

The appldata_ops callbacks are called with a spin_lock held. But the
appldata_mem callback then calls all_vm_events(), which calls
get_online_cpus(), which might sleep. This possible deadlock is fixed
by using a mutex instead of a spin_lock.

Subject: [S390] /proc/stat idle field for idle cpus

The cpu idle field in the output of /proc/stat is too small for cpus
that have been idle for more than a tick. Add the architecture hook
arch_idle_time that allows to add the not accounted idle time of a
sleeping cpu without waking the cpu.

The s390 implementation of arch_idle_time uses the already existing
s390_idle_data per_cpu variable to find the sleep time of a neighboring
idle cpu.

Subject: [S390] omit frame pointers on s390 when possible

Always omit frame pointers on s390. They aren't too useful for the
kernel since we have already the kernel stack backchain which allows
us to walk the kernel stack.
So eleminate the extra code for frame pointers. Only allow the extra
code for the function tracer since the gcc compile options -pg and
-fomit-frame-pointer are incompatible.

Subject: Revert "powerpc: Add support for early tlbilx opcode"

This reverts commit e9965577406a2148ade97b5e0ce7c448b4ba4ef6.  Our HW
guys were able to fix this so it never sees the light of day.

I removed it because of show_regs can't break die function.
If process/kernel failed, die (do_exit) function resolve it.

From c5b736d093217890245a33e9a98fe92d6f3529bf Mon Sep 17 00:00:00 2001
From: Kevin Hilman

Subject: davinci: major rework of clock, PLL, PSC infrastructure

This is a significant rework of the low-level clock, PLL and Power
Sleep Controller (PSC) implementation for the DaVinci family.  The
primary goal is to have better modeling if the hardware clocks and
features with the aim of DVFS functionality.

Highlights:
- model PLLs and all PLL-derived clocks
- model parent/child relationships of PLLs and clocks
- convert to new clkdev layer
- view clock frequency and refcount via /proc/davinci_clocks

Special thanks to significant contributions and testing by David
Brownell.

From f5c122da543ebf98a5ccb3166768e38eea3120dd Mon Sep 17 00:00:00 2001
From: Kevin Hilman
Date: Tue, 14 Apr 2009 07:04:16 -0500
Subject: davinci: add arch_ioremap() which uses existing static mappings

Add arch-specific ioremap() which uses any existing static mappings in
place of doing a new mapping.  From now on, drivers should always use
ioremap() instead of IO_ADDRESS().

In addition, remove the davinci_[read|write]* macros in favor of using
ioremap.

Subject: ARM: OMAP: Fix for possible race condition in omap_free_dma()

Fix the possible race condition in omap_free_dma(). Function omap_free_dma()
sets the dev_id = -1 and then accesses the channel afterwards to clear it.
But setting the dev_id=-1 makes the channel available for allocation again.
So it is possible someone else can grab it and results are unpredictable.
To avod this DMA channle is cleared first and then the dev_id = -1 is set.

Thanks to McNeil, Sean <sean.mcneil@ti.com> for ointing out this issue.

vi arch/arm/mach-omap2/usb-tusb6010.c +200	- tusb6010_platform_retime()
vi arch/arm/mach-omap2/gpmc.c +94		- gpmc_get_fclk_period()
vi arch/arm/mach-omap2/usb-tusb6010.c +53	- tusb_set_async_mode()
vi arch/arm/mach-omap2/usb-tusb6010.c +111	- tusb_set_sync_mode()

is -ENODEV appropriate when sysclk_ps == 0?

This was found by code analysis, please review.
------------------------------>8-------------8<---------------------------------
gpmc_get_fclk_period() may return 0 when gpmc_l3_clk is not enabled. This is
not checked in tusb6010_platform_retime() nor in tusb_set_async_mode() it
seems. In tusb_set_sync_mode() this may result in a division by zero.

Subject: ARM: OMAP2/3: GPIO: do not attempt to wake-enable

The GPIO IRQ enable/disable path attempts to also enable IRQ wake
support for the parent GPIO bank IRQ as well.  However, since there is
no 'set_wake' hook for the bank IRQs, these calls will always fail.
Also, since the enable will fail on the suspend path, the disable on
the resume path will trigger unbalanced enable/disable warnings.

This was discovered in the suspend/resume path on OMAP3/Beagle using
the gpio-keys driver which disables/re-enables GPIO IRQ wakeups in the
suspend/resume path.

Subject: palm_bk3710: those registers/bitfields don't exist

Bugfixes noted by checking the code against the controller
documentation (TI document number SPRUE21):

 - Remove declarations for eight non-existent registers (!);
   and remove accesses to two of them.

 - Remove access to various non-existent bitfields in some of
   the registers which *do* exist (those fields must-be-zero).

 - Provide comment to replace bogus reset logic (removed above,
   it relied on non-existent bitfields).  Resets require GPIO
   help; this driver doesn't currently know about that.

With some minor cleanup:  relocate a comment, avoid an extra
lookup of the PIO timings.

Subject: USB: serial: fix lifetime and locking problems

This patch (as1229) fixes a few lifetime and locking problems in the
usb-serial driver.  The main symptom is that an invalid kevent is
created when the serial device is unplugged while a connection is
active.

	Ports should be unregistered when device is disconnected,
	not when the parent usb_serial structure is deallocated.

	Each open file should hold a reference to the corresponding
	port structure, and the reference should be released when
	the file is closed.

	serial->disc_mutex should be acquired in serial_open(), to
	resolve the classic race between open and disconnect.

	serial_close() doesn't need to hold both serial->disc_mutex
	and port->mutex at the same time.

	Release the subdriver's module reference only after releasing
	all the other references, in case one of the release routines
	needs to invoke some code in the subdriver module.

	Replace a call to flush_scheduled_work() (which is prone to
	deadlocks) with cancel_work_sync().  Also, add a call to
	cancel_work_sync() in the disconnect routine.

	Reduce the scope of serial->disc_mutex in serial_disconnect().
	The only place it really needs to protect is where the
	"disconnected" flag is set.

This fixes the bug reported in

	http://bugs.freedesktop.org/show_bug.cgi?id=20703

Subject: USB: ehci-sched.c: EHCI SITD scheduling bugfix

Without this patch, the driver won't check that the last fully-occupied
uframe for a new split transaction was vacant beforehand.  This can
lead to a situation in which the first 188 bytes of a 192-byte
isochronous transfer are scheduled in the same uframe as an existing
interrupt transfer.  The resulting schedule looks like this:

       uframe 0: 188-byte isoc-OUT SSPLIT, 8-byte int-IN SSPLIT
       uframe 1: 4-byte isoc-OUT SSPLIT

The SSPLITs are intermingled, causing an error in the downstream hub's
TT.

If you are having problems with devices or hub ports resetting, or failed
interrupt transfers, when you start using a USB audio or video (Isochronous)
device, this patch may help.

Subject: USB: g_file_storage: fix use-after-free bug when closing files

This patch (as1231) fixes a use-after-free bug in g_file_storage.  A
device's name may not be available after the device is unregistered,
even if the device structure itself is still allocated.  Since
close_backing_file() prints a LUN's name for debugging, it shouldn't
be called after the LUN has been unregistered.

That whole area needed to be cleaned up; the backing files were
getting closed in a couple of different places.  The patch fixes
things so that they get closed in just one place, as part of the
unbind procedure, immediately before the LUN is unregistered.

Subject: USB: pass mem_flags to dma_alloc_coherent

When I want to use my webcam, I get:

Oddly, I remembered fixing this and putting in __GFP_NOWARN
because uvcvideo retries a smaller allocation. However, the
allocation function doesn't pass the gfp flags through to
dma_alloc_coherent so we still get the warning!

Subject: USB: serial: sierra driver bug fix for composite interface

This patch fixes a problem in sierra_send_setup() function when
composite devices are used. One should not be sending ACM commands to
interfaces that are OBEX. Doing this causes an apparent failure as the
ACM command has to time out before the interface can start being used.

Subject: USB: otg: Fix bug on remove path without transceiver

In the case where a gadget driver is removed while no
transceiver was found at probe time, a bug in
otg_put_transceiver() will trigger.

Provide symetric calls for otg_get_transceiver() and
otg_put_transceiver(), wherever a transceiver was found or
not.

Subject: ocfs2: Add missing iput() during error handling in
 ocfs2_dentry_attach_lock()

In ocfs2_dentry_attach_lock(), if unable to get the dentry lock, we need to
call iput(inode) because a failure here means no d_instantiate(), which means
the normally matching iput() will not be called during dput(dentry).

This patch fixes the oops that accompanies the following message:
(3996,1):dlm_empty_lockres:2708 ERROR: lockres W00000000000000000a1046b06a4382 still has local locks!
kernel BUG in dlm_empty_lockres at /rpmbuild/smushran/BUILD/ocfs2-1.4.2/fs/ocfs2/dlm/dlmmaster.c:2709!

Subject: [ARM] 5460/1: Orion: reduce namespace pollution

Symbols like SOFT_RESET are way too generic to be exported at large.
To avoid this, let's move the mbus bridge register defines into a
separate file and include it where needed.  This affects mach-kirkwood,
mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.

Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.

This fixes compilation problem with mpt2sas on the above listed
platforms.

Subject: ACPI/hpet: prevent boot hang when hpet=force used on ICH-4M

Linux tells ICH4 users that they can (manually) invoke
"hpet=force" to enable the undocumented ICH-4M HPET.
The HPET becomes available for both clocksource and clockevents.

But as of ff69f2bba67bd45514923aaedbf40fe351787c59
(acpi: fix of pmtimer overflow that make Cx states time incorrect)
the HPET may be used via clocksource for idle accounting, and
hpet=force on an ICH4 box hangs boot.

It turns out that touching the MMIO HPET withing
the ARB_DIS part of C3 will hang the hardware.

The fix is to simply move the timer access outside
the ARB_DIS region.  This is a no-op on modern hardware
because ARB_DIS is no longer used.

Subject: OMAP2xxx clock: fix broken cpu_mask code

Commit 8ad8ff6548f1c0bcbeaa02f274b3927c5015a921 breaks the OMAP2xxx
cpu_mask code, which causes OMAP2xxx to panic on boot.  Fix by
removing the cpu_mask auto variable and by changing CK_242X
and CK_243X to use RATE_IN_242X/RATE_IN_243X.

Resolves

Subject: OMAP3: clock: Camera module doesn't have IDLEST bit

This patch avoids waiting for the camera module to become ready,
since it doesn't have IDLEST bit.

Based on a earlier hack done by Paul Walmsley on Sep 9 2008 on
linux-omap tree.

Subject: OMAP2/3 GPTIMER: allow system tick GPTIMER to be changed in board-*.c
 files

Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files
to use in .init_irq functions to configure the system tick GPTIMER.
Practical choices at this point are GPTIMER1 or GPTIMER12.  Both of
these timers are in the WKUP powerdomain, and so are unaffected by
chip power management.  GPTIMER1 can use sys_clk as a source, for
applications where a high-resolution timer is more important than
power management.  GPTIMER12 has the special property that it has the
secure 32kHz oscillator as its source clock, which may be less prone
to glitches than the off-chip 32kHz oscillator.  But on HS devices, it
may not be available for Linux use.

It appears that most boards are fine with GPTIMER1, but BeagleBoard
should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs
in revisions B4 and below.  Modify board-omap3beagle.c to use GPTIMER12.

This patch originally used a Kbuild config option to select the GPTIMER,
but was changed to allow this to be specified in board-*.c files, per
Tony's request.

Kalle Vallo <kalle.valo@nokia.com> found a bug in an earlier version of
this patch - thanks Kalle.

Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and
3430SDP.

As processor.max_cstate is an init-time-only modparam,
sanity checking it at init-time is sufficient.

Subject: ACPI: EC: Fix ACPI EC resume non-query interrupt message

When resuming from standby (on a laptop) I see the following message in
my kernel.log:
"ACPI: EC: non-query interrupt received, switching to interrupt mode"
This apparently prevented sony-laptop to properly restore the brightness
level on resume.

The cause: In drivers/acpi/ec.c the acpi_ec_suspend function clears the
GPE mode bit, but this is not restored in acpi_ec_resume (the function
below it). The patch below fixes this by properly restoring the GPE_MODE
bit. Tested and confirmed to work.

Subject: sony-laptop: always try to unblock rfkill on load

This fixes an inconsistent behaviour when loading the driver with the
switch on or off. In the former case you would also need to soft unblock
the switch via the sysfs file entries to really disable rfkill, in the
latter you wouldn't.

For windows compatibility,
1) On a port protection violation, simply ignore the request and
   do not return an exception (allow the control method to continue execution.)
2) If only part of the request overlaps a protected port,
   read/write the individual ports that are not protected.

was only being performed in the KMS case. Ensure it's done even if we

Subject: drm/kms: don't try to shortcut drm mode set function

We have a drm_set_config which takes a crtc/encoder/mode setup,
and checks it to see if it can shortcut and just do a base setup,
or whether a complete mode setting is required.

The HPET in the ICH4M is not documented in the data sheet
because it was not officially validated.

While it is fine for hackers to continue to use "hpet=force"
to enable the hardware that they have, it is not prudent to
solicit additional "hpet=force" users on this hardware.

[ Impact: remove hpet=force syslog message on old-ICH systems ]

This simplifies I/O stat accounting switching code and separates it
completely from I/O scheduler switch code.

Requests are accounted according to the state of their request queue
at the time of the request allocation. There is no need anymore to
flush the request queue when switching I/O accounting state.

Subject: umem: fix request_queue lock warning

The umem driver issues two warnings on boot, due to blk_plug_device() and
blk_remove_plug() being called without q->queue_lock held.  Starting with
e48ec690 (block: extend queue_flag bitops), the queue_flag_* functions
warn if q->queue_lock doesn't appear to be locked.  In fact, q->queue_lock
is NULL (though that apparently isn't otherwise a problem as the driver is
using card->lock for everything).

Although blk_init_queue() with take a request_fn_proc and spinlock_t*,
there isn't a corresponding init helper that takes a make_request_fn.
Setting queue_lock to &card->lock explicitly seems to work fine for me.
The warning goes away and the device appears to behave.

Subject: block: fix intermittent dm timeout based oops

Very rarely under stress testing of dm, oopses are occuring as
something tampers with an old stack frame.  This has been traced back
to blk_abort_queue() leaving a timeout_list pointing to the stack.
The reason is that sometimes blk_abort_request() won't delete the
timer (if the request is marked as complete but before the timer has
been removed, a small race window).  Fix this by splicing back from
the ususally empty list to the q->timeout_list.

Subject: cfq-iosched: fix bug with aliased request and cooperation detection

cfq_prio_tree_lookup() should return the direct match, yet it always
returns zero. Fix that.

cfq_prio_tree_add() assumes that we don't get a direct match, while
it is very possible that we do. Using O_DIRECT, you can have different
cfqq with matching requests, since you don't have the page cache
to serialize things for you. Fix this bug by only adding the cfqq if
there isn't an existing match.

Subject: cfq-iosched: cache prio_tree root in cfqq->p_root

Currently we look it up from ->ioprio, but ->ioprio can change if
either the process gets its IO priority changed explicitly, or if
cfq decides to temporarily boost it. So if we are unlucky, we can
end up attempting to remove a node from a different rbtree root than
where it was added.

Fix this by using ->org_ioprio as the prio_tree index, since that
will only change for explicit IO priority settings (not for a boost).
Additionally cache the rbtree root inside the cfqq, then we don't have
to add code to reinsert the cfqq in the prio_tree if IO priority changes.

Subject: powerpc/44x: Correct memory size calculation for denali-based boards

Some U-Boot versions incorrectly set the number of chipselects to two
for Sequoia/Rainier boards while they only have one chipselect hardwired.
This patch adds a workaround for this, hardcoding the number of chipselects
to one for sequioa/rainer board models and reading the actual value from
the memory controller register DDR0_10 otherwise.

It also fixes another error in the way ibm4xx_denali_fixup_memsize
calculates memory size. When testing the DDR_REDUC bit, the polarity is
backwards.  A "1" implies 32-bit wide memory while a "0" implies 64-bit
wide memory.

Subject: do_execve() must not clear fs->in_exec if it was set by another
 thread

If do_execve() fails after check_unsafe_exec(), it clears fs->in_exec
unconditionally. This is wrong if we race with our sub-thread which
also does do_execve:

	Two threads T1 and T2 and another process P, all share the same
	->fs.

	T1 starts do_execve(BAD_FILE). It calls check_unsafe_exec(), since
	->fs is shared, we set LSM_UNSAFE but not ->in_exec.

	P exits and decrements fs->users.

	T2 starts do_execve(), calls check_unsafe_exec(), now ->fs is not
	shared, we set fs->in_exec.

	T1 continues, open_exec(BAD_FILE) fails, we clear ->in_exec and
	return to the user-space.

	T1 does clone(CLONE_FS /* without CLONE_THREAD */).

	T2 continues without LSM_UNSAFE_SHARE while ->fs is shared with
	another process.

Change check_unsafe_exec() to return res = 1 if we set ->in_exec, and change
do_execve() to clear ->in_exec depending on res.

When do_execve() suceeds, it is safe to clear ->in_exec unconditionally.
It can be set only if we don't share ->fs with another process, and since
we already killed all sub-threads either ->in_exec == 0 or we are the
only user of this ->fs.

Also, we do not need fs->lock to clear fs->in_exec.

Subject: check_unsafe_exec: s/lock_task_sighand/rcu_read_lock/

write_lock(&current->fs->lock) guarantees we can't wrongly miss
LSM_UNSAFE_SHARE, this is what we care about. Use rcu_read_lock()
instead of ->siglock to iterate over the sub-threads. We must see
all CLONE_THREAD|CLONE_FS threads which didn't pass exit_fs(), it
takes fs->lock too.

With or without this patch we can miss the freshly cloned thread
and set LSM_UNSAFE_SHARE, we don't care.

Subject: Delete slow-work timers properly

Slow-work appears to delete its timer as soon as the first user
unregisters, even though other users could be active.  At the same time, it
never seems to delete slow_work_oom_timer.  Arrange for both to happen in
the shutdown path.

Subject: ext4: Fix softlockup caused by illegal i_file_acl value in on-disk
 inode

If the block containing external extended attributes (which is stored
in i_file_acl and i_file_acl_high) is larger than the on-disk
filesystem, the process which tried to access the extended attributes
will endlessly issue kernel printks complaining that
"__find_get_block_slow() failed", locking up that CPU until the system
is forcibly rebooted.

So when we read in the inode, make sure the i_file_acl value is legal,
and if not, flag the filesystem as being corrupted.

Subject: Btrfs: try to keep a healthy ratio of metadata vs data block groups

This patch makes the chunk allocator keep a good ratio of metadata vs data
block groups.  By default for every 8 data block groups, we'll allocate 1
metadata chunk, or about 12% of the disk will be allocated for metadata.  This
can be changed by specifying the metadata_ratio mount option.

This is simply the number of data block groups that have to be allocated to
force a metadata chunk allocation.  By making sure we allocate metadata chunks
more often, we are less likely to get into situations where the whole disk
has been allocated as data block groups.

Subject: Btrfs: don't export symbols

Currently the extent_map code is only for btrfs so don't export it's
symbols.

Subject: Btrfs: fix fallocate deadlock on inode extent lock

The btrfs fallocate call takes an extent lock on the entire range
being fallocated, and then runs through insert_reserved_extent on each
extent as they are allocated.

The problem with this is that btrfs_drop_extents may decide to try
and take the same extent lock fallocate was already holding.  The solution
used here is to push down knowledge of the range that is already locked
going into btrfs_drop_extents.

It turns out that at least one other caller had the same bug.

Subject: Btrfs: fix deadlocks and stalls on dead root removal

After a transaction commit, the old root of the subvol btrees are sent through
snapshot removal.  This is what actually frees up any blocks replaced by
COW, and anything the old blocks pointed to.

Snapshot deletion will pause when a transaction commit has started, which
helps to avoid a huge amount of delayed reference count updates piling up
as the transaction is trying to close.

But, this pause happens after the snapshot deletion process has asked other
procs on the system to throttle back a bit so that it can make progress.

We don't want to throttle everyone while we're waiting for the transaction
commit, it leads to deadlocks in the user transaction ioctls used by Ceph
and makes things slower in general.

This patch changes things to avoid the throttling while we sleep.

Subject: ext4: Ignore i_file_acl_high unless EXT4_FEATURE_INCOMPAT_64BIT is
 present

Don't try to look at i_file_acl_high unless the INCOMPAT_64BIT feature
bit is set.  The field is normally zero, but older versions of e2fsck
didn't automatically check to make sure of this, so in the spirit of
"be liberal in what you accept", don't look at i_file_acl_high unless
we are using a 64-bit filesystem.

Subject: virtio-rng: Remove false BUG for spurious callbacks

The virtio-rng drivers checks for spurious callbacks. Since
callbacks can be implemented via shared interrupts (e.g. PCI) this
could lead to guest kernel oopses with lots of virtio devices.

Subject: ROMFS: romfs_lookup() shouldn't be doing a partial name comparison

romfs_lookup() should be using a routine akin to strcmp() on the backing store,
rather than one akin to strncmp().  If it uses the latter, it's liable to match
/bin/shutdown when looking up /bin/sh.

Subject: ROMFS: Advance destination buffer pointer when reading from a

RomFS should advance the destination buffer pointer when reading data from a
blockdev source (the data may be split over multiple blocks, each requiring its
own sb_read() call).  Without this, all the data is copied to the beginning of
the output buffer.

Subject: PM/Hibernate: Fix waiting for image device to appear on resume

Commit c751085943362143f84346d274e0011419c84202 ("PM/Hibernate: Wait for
SCSI devices scan to complete during resume") added a call to
scsi_complete_async_scans() to software_resume(), so that it waited for
the SCSI scanning to complete, but the call was added at a wrong place.

Namely, it should have been added after wait_for_device_probe(), which
is called only if the image partition hasn't been specified yet.  Also,
it's reasonable to check if the image partition is present and only wait
for the device probing and SCSI scanning to complete if it is not the
case.

Additionally, since noresume is checked right at the beginning of
software_resume() and the function returns immediately if it's set, it
doesn't make sense to check it once again later.

Subject: ext4: Do not try to validate extents on special files

The EXTENTS_FL flag should never be set on special files, but if it
is, don't bother trying to validate that the extents tree is valid,
since only files, directories, and non-fast symlinks will ever have an
extent data structure.  We perhaps should flag the filesystem as being
corrupted if we see a special file (named pipes, device nodes, Unix
domain sockets, etc.) with the EXTENTS_FL flag, but e2fsck doesn't
currently check this case, so we'll just ignore this for now, since
it's harmless.

Without this fix, a special device with the extents flag is flagged as
an error by the kernel, so it is impossible to access or delete the
inode, but e2fsck doesn't see it as a problem, leading to
confused/frustrated users.

TO_DEVICE instead of FROM_DEVICE.  This causes data corruption on non
cache-coherent systems if frmrs are used.

Subject: Add new HEAD_TEXT_SECTION macro.

This patch is preparation for replacing all uses of ".head.text" or
".text.head" in the kernel with macros, so that the section name can
later be changed without having to touch a lot of the kernel.

Since some linker scripts do more complex things than referencing
HEAD_TEXT, we add a HEAD_TEXT_SECTION macro that just contains the
actual name.

I've defined HEAD_TEXT_SECTION in a new header,
include/linux/section-names.h, so that this section name only needs to
appear in one place.  I anticipate creating similar macro structures
for a number of other section names.

The long-term goal here is to be able to change the kernel's magic
section names to those that are compatible with -ffunction-sections
-fdata-sections.  This requires renaming all magic sections with names
of the form ".text.foo".

This has the consequence of changing the section name use for head
code from ".text.head" to ".head.text".  Since this commit changes all
users in the architecture, this change should be harmless.

Subject: locking: Documentation: lockdep-design.txt, fix note of state bits

From source code of get_usage_char(), the previous note is not correct,
so fix it.

static char get_usage_char(struct lock_class *class, enum lock_usage_bit bit)
{
	char c = '.';

	if (class->usage_mask & lock_flag(bit + 2))/*LOCK_ENABLED_##STATE*/
		c = '+';
	if (class->usage_mask & lock_flag(bit)) {/*LOCK_USED_IN_##STATE*/
		c = '-';
		if (class->usage_mask & lock_flag(bit + 2))
			c = '?';
	}

	return c;
}

note:

1) The 'bit' parameter always is passed as  LOCK_USED_IN_##STATE
   or LOCK_USED_IN_##STATE_READ , from get_usage_chars().

Subject: dma-debug: remove broken dma memory leak detection for 2.6.30

The feature needs some more work because the notfier which is used to
check for pending allocations is called before the device drivers
->remove() function. Therefore this feature reports false positives.

A real fix for this issue is to introduce a new notifier event which sent
_after_ the driver has deinitialized itself. That will done for the next
kernel version.

[ Impact: reduce the scope of CONFIG_DMA_API_DEBUG=y checks ]

Here is a fix for this, keeping an open and close, so reducing
the load on the system when the mouse is not in use, and also properly
referencing the maple device buffer following the recent update.

Subject: [ARM] pxa: fix issue of muxed GPIO irq_chip functions touching
 non-muxed GPIOs

pxa_gpio_irq_type() and pxa_unmask_muxed_gpio() will touch non-muxed GPIOs
(0 and 1 on PXA2xx/PXA3xx) bits in GRERx and GFERx, which is incorrect.
Actually, only those bits should get updated if the corresponding bits are
set in c->irq_mask as well. Fix this by updating only those relevant bits.

Subject: [ARM] pxa/zylonite: fix the issue of unused SDATA_IN_1 pin get AC97
 not working

GPIO17_SDATA_IN_1 and GPIO36_SDATA_IN_1 are originally designed for the 2nd
codec but unused on the board, yet they are initialized incorrectly by the
bootloader as the SDATA_IN_1 alternate function, thus causing AC97 fail to
work. Fix this issue by configuring these pins as normal GPIO to avoid the
noise from these pins being treated as signals from the 2nd codec.

Subject: sh: Fix up unsigned syscall_nr in SH-5 pt_regs.

syscall_nr is presently defined as unsigned in the SH-5 pt_regs,
while the syscall restarting code wants it to be signed. Fix this
up, and bring it in line with the other SH parts.

Subject: Btrfs: When shrinking, only update disk size on success

Previously, we updated a device's size prior to attempting a shrink
operation.  This patch moves the device resizing logic to only happen if
the shrink completes successfully.  In the process, it introduces a new
field to btrfs_device -- disk_total_bytes -- to track the on-disk size.

Subject: Btrfs: ratelimit IO error printks

Btrfs has printks for various IO errors, including bad checksums and
mismatches between what we expect the block headers to contain and what
we actually find on the disk.

Longer term we need a real reporting mechanism for this, but for now
printk is going to have to do.

Subject: Btrfs: Fix a trivial warning using max() of u64 vs ULL.

A small warning popped up on ia64 because inode-map.c was comparing a
u64 object id with the ULL FIRST_FREE_OBJECTID.  My first thought was
that all the OBJECTID constants should contain the u64 cast because
btrfs code deals entirely in u64s.  But then I saw how large that was,
and figured I'd just fix the max() call.

Subject: [SCSI] sr: report more accurate drive status after closing the tray.

So, what's happening here is that the drive is reporting a sense of
2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and
then we ask for the media event notification before checking that result
at all.  The check_media_event_descriptor() call isn't getting a check
condition, but it's also reporting that the tray is closed and that
there's no media.  In actuality it doesn't yet know if there's media or
not, but there's no way to express that in the media event status field.

My current thought is that if it told us the device isn't yet ready, we
should return that immediately, since there's nothing that'll tell us
any more data than that reliably:

Subject: [SCSI] sg: return EFAULT for an invalid user address

blk_rq_unmap_user() returns EFAULT if a program passes an invalid
address to kernel (the kernel fails to copy data to user space). sg
needs to pass the returned value to user space instead of ignoring
it. Before the block layer conversion, sg returns EFAULT
properly. This restores the old behavior.

Subject: [SCSI] lpfc 8.3.1: misc fixes/changes

8.3.1 Fixes/Changes :

- Fix incorrect byte-swapping on word 4 of IOCB (data length) which
  caused LUNs to not be discovered on big-endian (e.g. PPC)

- Remove a bad cast of MBslimaddr which loses the __iomem (sparse)

- Make lpfc_debugfs_mask_disc_trc static (sparse)

- Correct misspelled word BlockGuard in lpfc_logmsg.h comment

- Replaced repeated code segment for canceling IOCBs from a list with
  a function call, lpfc_sli_cancel_iocbs().

- Increased HBQ buffers to support 40KB SSC sequences.

- Added sysfs interface to update speed and topology parameter without
  link bounce.

- Fixed bug with sysfs fc_host WWNs not being updated after changing
  the WWNs.

- Check if the active mailbox is NULL in the beginning of the mailbox
  timeout handler - fixes panic in the mailbox timeout handler while
  running IO stress test

- Fixed system panic in lpfc_pci_remove_one() due to ndlp indirect
  reference to phba through vport

- Removed de-reference of scsi device after call to scsi_done() to fix
  panic in scsi completion path while accessing scsi device after
  scsi_done is called.

- Fixed "Nodelist not empty" message when unloading the driver after
  target reboot test

- Added LP2105 HBA model description

- Added code to print all 16 words of unrecognized ASYNC events

- Fixed memory leak in vport create + delete loop

- Added support for handling dual error bit from HBA

- Fixed a driver NULL pointer dereference in lpfc_sli_process_sol_iocb

- Fixed a discovery bug with FC switch reboot in lpfc_setup_disc_node

- Take NULL termintator into account when calculating available buffer space

Subject: [SCSI] fix q->lock not held warning when target is busy

We cannot call blk_plug_device from scsi_target_queue_ready
because the q lock is not held. And we do not need to call
it from there because when we return 0, the scsi_request_fn
not_ready handling will plug the queue for us if needed.

Subject: FRV: Stop gcc from generating uninitialised variable warnings after
 BUG()

Stop gcc from generating uninitialised variable warnings after BUG().
The problem is that FRV's call into its gdbstub appears to return (if
the function is marked noreturn, then the compiler is under no
obligation to pass it a return address, and so GDB won't know where the
bug happened).

To get around this, we make the do...while wrapper in _debug_bug_trap()
an endless loop from which there's no escape.

When running the scsi_scan from the zfcp workqueue and the target
device does not respond, the zfcp workqueue can block until the
scsi_scan hits a timeout. Move the work to the scsi host workqueue,
since this one is also used for the scan from the SCSI midlayer.

Subject: [SCSI] zfcp: Set WKA-port to offline on adapter deactivation

The nameserver port might be in state online when the adapter is
offlined. On adapter reactivation the nameserver port is not
re-opened due to the PORT_ONLINE status. This results in an
unsuccessful recovery. In forcing the nameserver port status
to offline on all adapter offline events this issue is prevented.

Waiting for the reference count to drop to zero in
zfcp_wka_port_offline is not required, so remove it.

Subject: [SCSI] zfcp: avoid false ERP complete due to sema race

The ERP thread is performing a task before it is executing the
corresponding down on the semaphore. The response handler of the
just started exchange config should wait for the completion by
performing a down on this semaphore. Since this semaphore is still
positive from the ERP enqueue the handler won't wait and therefore
the exchange config will always fail leaving the adapter in error.
The problem can be solved by performing the down on the semaphore
before starting an ERP task. This is the logically correct order.
Only walk the ERP loop if there is a task to perform.

Subject: [SCSI] zfcp: no port recovery after storage side error inject

The remote port remains in error state even if the connection
is re-established. A wrong precondition check was performed on
the port status leading to a cancellation of the port reopen.
Remove the pre-req check because it's not required and better
handled within the ERP.

A remote port remains in error state even if we receive a RSCN
stating that the connection is re-established. The port recovery
is not started due to a flag which is not reset.
The solution is to clear the flag in question before we trigger a ERP.

When the abort handler cannot find a pending FSF request, the request

since this would lead to call to scsi_done after exiting the SCSI
error handler which is not allowed.

Subject: [SCSI] zfcp: Fix port reference counting

If this problem appears zfcp ports cannot be de-queued since it is
checked for a zero refcount. The port reference counting is wrong for
existing zfcp ports when e.g. an adapter gets on-line again. During
port scanning the reference counting for existing ports should not be
changed.

Subject: [SCSI] zfcp: Fix oops when port disappears

The zfcp_port might have been removed, while the FC fast_io_fail timer
is still running and could trigger the terminate_rport_io callback.
Set the pointer to the zfcp_port to NULL and check accordingly
before using it.

Subject: [SCSI] iscsi_tcp: don't fire conn error if pdu init fails

If a command's scsi cmd pdu setup fails then we can just fail
the IO to the scsi layer. If a DATA_OUT for a R2T fails then
we will want to drop the session, because it means we got a
bad request from the target (iscsi protocol error).

This patch has us propogate the error upwards so libiscsi_tcp
or libiscsi can decide what the best action is to take. It
also fixes a bug where we could try to grab the session lock
while holding it, because if iscsi_tcp drops the session in the
pdu setup callout the session lock is held when setting up the
scsi cmd pdu.

cxgb3i was setting can_queue to only 128 commands, and was
setting the can_queue and cmd_per_lun to the same value.

This sets the can_queue to 1024 commands, and sets the cmd_per_lun
to a safer default of 32.

Subject: [SCSI] cxgb3i: fix cpu use abuse during writes

When doing a lot (128) of large writes (256K) we can hit the cxgb3_snd_win
check pretty easily. The driver's xmit thread then takes 100% of the cpu.

The driver should not be returning -EAGAIN for this problem. It should
be returing -ENOBUFS, then when the window is opened again it should
queue the xmit thread (it already wakes the xmit thread).

Subject: [SCSI] cxgb3i: fix ddp map overrun

(version 2)

Fixed a bug in calculating ddp map range when search for free entries:
it was going beyond the end by one, thus corrupting gl_skb[0].

Subject: [SCSI] libfc: Hold disc mutex while processing gpn ft resp

gpn_ft_resp processing currently does not hold the discovery lock.
disc_done() thus gets called from gpn_ft_resp or from gpn_ft_parse
without the lock held. This then sets disc->pending to zero or calls
gpn_ft_req() without disc_lock held.

- Hold disc mutex during gpn_ft resp processing
- In disc_done, release the disc mutex while calling lport callback

Subject: [SCSI] libfc: Do not retry if the new state is not the same as old
 state

For instance, if there is a Plogi pending (remote port is in Plogi state),
and the state changes to say NONE (because the port is being logged off),
then when the Plogi resp times out, do not start a retry.

This patch partially reverts an earlier patch (libfc: check for err when
recv and state is incorrect), by moving the state check back to before
checking for error. However, if the state does not match, then there is
an additional check to see if its an error ptr or a real frame before
jumping to err or out respectively.

Subject: [SCSI] libfc: Track rogue remote ports

Rogue ports are currently not tracked on any list. The only reference
to them is through any outstanding exchanges pending on the rogue ports.
If the module is removed while a retry is set on a rogue port
(say a Plogi retry for instance), this retry is not cancelled because there
is no reference to the rogue port in the discovery rports list. Thus the
local port can clean itself up, delete the exchange pool, and then the
rogue port timeout can fire and try to start up another exchange.

This patch tracks the rogue ports in a new list disc->rogue_rports. Creating
a new list instead of using the disc->rports list keeps remote port code
change to a minimum.

1)  Whenever a rogue port is created, it is immediately added to the
disc->rogue_rports list.

2) When the rogues port goes to ready, it is removed from the rogue list
and the real remote port is added to the disc->rports list

3) The removal of the rogue from the disc->rogue_rports list is done in
the context of the fc_rport_work() workQ thread in discovery callback.

4) Real rports are removed from the disc->rports list like before. Lookup
is done only in the real rports list. This avoids making large changes
to the remote port code.

5) In fc_disc_stop_rports, the rogues list is traversed in addition to the
real list to stop the rogue ports and issue logoffs on them. This way, rogue
ports get cleaned up when the local port goes away.

6) rogue remote ports are not removed from the list right away, but
removed late in fc_rport_work() context, multiple threads can find the same
remote port in the list and call rport_logoff(). Rport_logoff() only
continues with the logoff if port is not in NONE state, thus preventing
multiple logoffs and multiple list deletions.

7) Since the rport is removed from the disc list at a later stage
(in the disc callback), incoming frames can find the rport even if
rport_logoff() has been called on the rport. When rport_logoff() is called,
the rport state is set to NONE, and we are trying to cancel all exchanges
and retries on that port. While in this state, if an incoming
Plogi/Prli/Logo or other frames match the rport, we should not reply
because the rport is in the NONE state. Just drop the frame, since the
rport will be deleted soon in the disc callback (fc_rport_work)

8)  In fc_disc_single(), remove rport lookup and call to fc_disc_del_target.
fc_disc_single() is called from recv_rscn_req() where rport lookup
and rport_logoff is already done.

Subject: [SCSI] libfc: During fabric logoff, flush the rport Q after logging
 off dns port

We want to generate the rport queue event (from the logoff)
before flushing the queue otherwise the event may still be
in the queue when we logoff.

Subject: [SCSI] libfc: Change state to NONE in fc_lport_destroy

After lport_destroy, the local port should not be used again. Transition
to state NONE, any incoming frames or link up should not transition out
of this state since we are deleting exchange table and cleaning up the
local port. Also, mark link as down.

Subject: [SCSI] libfc: Fix compilation warnings with allmodconfig

When building with a .config generated from 'make allmodconfig'
some build warnings are generated. This patch corrects the warnings,
adds a FC_FID_NONE (= 0) enumeration for FC-IDs and cleans up one
variable naming to meet our variable naming conventions. For example,
fc_lport's should be named "lport," not "lp."

The FCoE forwarder (FCF) would be selected, but then would soon time
out after three advertisements were missed.  This would be 24 seconds
by default, or 3 times the keep-alive interval configured on the switch.

The cause was that the multicast address for all FIP E-nodes
was never added.

Subject: [SCSI] fix sign extension with 1.5TB usb-storage LBD=y

Shifting an unsigned char implicitly casts it to a signed int.  This
caused 'lba' to sign-extend and Linux would then try READ CAPACITY 16
which was not supported by at least one drive.  Using the
get_unaligned_be*() helpers keeps us from having to worry about how the
extension might occur.

Subject: [SCSI] mpt2sas : the sanity check in base_interrupt needs to be on
 dword boundary

The poison sanity check on the reply_post_free register needs to be by 32bit,
not 64bit. The poison check is there because its possible that the driver read
the 1st 32bit before the 2nd 32bit has been written to by firmware.  In other
words, this handles race between driver reading the 64 bit register, and it
being dma'd across pci memory from controller firmware as two 32bit pci writes.

There is a bug in firmware where the reply message frame says there is a

the memcpy action doesn't corrupte the memory beyond the 90 bytes allocated in
the scsi command for sense buffer.

Subject: [SCSI] mpt2sas : driver name needs to be in the MPT2IOCINFO ioctl

The driver name needs to be at the beginining of the driver_version string in
MPT2IOCINFO ioctl.  This is the same behaviour is there already in the mptsas
driver.

Subject: [SCSI] mpt2sas : Identify Dell series-7 adapters at driver load time

The Dell branding along with the VID, DID, SSVID, SSDID following the LSI
branding that contains the card firmware/chip/bios versions.  If the SSDID
is not known but it is a Dell HBA, the driver will print the SSDID instead
of the Dell branding string.  Nothing will be printed for non Dell HBAs

Subject: [SCSI] mpt2sas : Broadcast Primative AEN bug fix

Bug fix in the broadcast primative async event code where the driver would
stop sending tm queries after the first queury was completed. This was due
driver not reseting the tm_cmds.status field back to MPT2_CMD_NOT_USED after
completing a task management request.

An addtional fix adding sanity check to insure sas_device->starget set to NULL.
During multipath testing fail over/fail back, the mid layer was holding onto
sdev longer than the fail back period, thus starget was getting set to NULL
for device being added.

Subject: [SCSI] mpt2sas : release diagnotic buffers prior host reset

Diagnostic buffer support is already there in the driver.  This support allows
applications to pull ring buffers from controller firmware for debugging
firmware related issues.

What this patch does is sends reqeust to firmware to release the buffers prior
to host reset.   This will allow what ever debug info is there prior to reset
to be dma'd to host memory. With out this fix, some of the debug data would
been lost.

Subject: [SCSI] mpt2sas: fix hotplug event processing

Here's a fix for hotplug events.  The useage of queue_delayed_work seems
to broke the fifo for processing of firmware events.  After several iterations
of adding and removing cabling connected to jbods, the devices are not
getting added becuase kernel thread is activited out of order.

Subject: [SCSI] libosd: OSD2r05: Prepare for rev5 attribute list changes

In OSD2r05 draft each attribute list element header was changed
so attribute-value would be 8 bytes aligned. In OSD2r01-r04
it was aligned on 2 bytes. (This is because in OSD2r01 the complete
element was 8 bytes padded at end but the header was not adjusted
and caused permanent miss-alignment.)

OSD1 elements are not padded and might be or might not be aligned.
OSD1 is still supported.

In this code we do all the code re-factoring to separate OSD1/OSD2
differences but do not change actual wire format. All wire format
changes will happen in one patch later, for bisect-ability.

Subject: [SCSI] libosd: OSD2r05: OSD_CRYPTO_KEYID_SIZE will grow 20 => 32
 bytes

In OSD2r04 draft, cryptographic key size changed to 32 bytes from
OSD1's 20 bytes. This causes a couple of on-the-wire structures
to change, including the CDB.

In this patch the OSD1/OSD2 handling is separated out in regard
to affected structures, but on-the-wire is still the same. All
on the wire changes will be submitted in one patch for bisect-ability.

Subject: [SCSI] libosd: OSD2r05: on-the-wire changes for latest OSD2 revision
 5.

OSC's OSD2 target: [git clone git://git.open-osd.org/osc-osd/ master]
(Initiator code prior to this patch must use: "git checkout CDB_VER_OSD2r01"
 in the target tree above)

This is a summery of the wire changes:

 * OSDv2_ADDITIONAL_CDB_LENGTH == 192 => 228 (Total CDB is now 236 bytes)
 * Attributes List Element Header grew, so attribute values are 8 bytes
   aligned.
 * Cryptographic keys and signatures are 20 => 32
 * Few new definitions.

(Still missing new standard definitions attribute values, these do not change
 wire format and will be added later when needed)

+/*
+ * This EDMA3 programming framework exposes two basic kinds of resource:
+ *
+ *  Channel	Triggers transfers, usually from a hardware event but
+ *		also manually or by "chaining" from DMA completions.
+ *		Each channel is coupled to a Parameter RAM (PaRAM) slot.
+ *
+ *  Slot	Each PaRAM slot holds a DMA transfer descriptor (PaRAM
+ *		"set"), source and destination addresses, a link to a
+ *		next PaRAM slot (if any), options for the transfer, and
+ *		instructions for updating those addresses.  There are
+ *		more than twice as many slots as event channels.
+ *
+ * Each PaRAM set describes a sequence of transfers, either for one large
+ * buffer or for several discontiguous smaller buffers.  An EDMA transfer
+ * is driven only from a channel, which performs the transfers specified
+ * in its PaRAM slot until there are no more transfers.  When that last
+ * transfer completes, the "link" field may be used to reload the channel's
+ * PaRAM slot with a new transfer descriptor.
+ *
+ * The EDMA Channel Controller (CC) maps requests from channels into physical
+ * Transfer Controller (TC) requests when the channel triggers (by hardware
+ * or software events, or by chaining).  The two physical DMA channels provided
+ * by the TCs are thus shared by many logical channels.
+ *
+ * DaVinci hardware also has a "QDMA" mechanism which is not currently
+ * supported through this interface.  (DSP firmware uses it though.)

From 474dad54baee8f8abe63ac334357a37021147701 Mon Sep 17 00:00:00 2001
From: David Brownell
Date: Sun, 7 Dec 2008 11:46:23 -0800
Subject: davinci: gpio bugfixes

Update the DaVinci GPIO code to work better on non-dm6446 parts,
notably the dm355:

 - Only handle the number of GPIOs the chip actually has.  So
   for example on dm6467, GPIO-42 is the last GPIO, and trying
   to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446.

 - Enable GPIO interrupts on each 16-bit GPIO-irq bank ...
   previously, only the first five were enabled, so GPIO-80
   and above (on dm355) wouldn't trigger IRQs.

 - Use the right IRQ for each GPIO bank.  The wrong values were
   used for dm355 chips, so GPIO IRQs got routed incorrectly.

 - Handle up to four pairs of 16-bit GPIO banks ... previously
   only three were handled, so accessing GPIO-96 and up (e.g. on
   dm355) would oops.

 - Update several comments that were dm6446-specific.

Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs
on the DM355 EVM.

One thing this doesn't do is handle the way some of the GPIO
numbers on dm6467 are reserved but aren't valid as GPIOs.  Some
bitmap logic could fix that if needed.

Subject: davinci: PSC: Clear bits in MDCTL reg before setting new bits

Clear any set bits in the 'NEXT' field of the MDCTL register in the
Power and Sleep Controller (PSC) before setting any new bits.
This also allows some minor cleanup by removing some no longer
needed lines of code.

Subject: davinci: update DM644x support in preparation for more SoCs

Rework DM644x code into SoC specific and board specific parts.
This is also to generalize the structure a bit so it's easier to add
support for new SoCs in the DaVinci family.

From 3e9c18e1dc71b9a0fac302e2defe99d850ad3d79 Mon Sep 17 00:00:00 2001
From: David Brownell

Subject: davinci: DM644x: NAND: update partitioning

Update NAND partitioning for the dm6446 evm, unmasking the hidden
data at the beginning and letting the kernel be updated from Linux.

 - This is boot-compatible with TI's software (U-Boot 1.20 and both
   the 2.6.10 and 2.6.18 kernels), in terms of startup and loading
   kernels from flash.

 - In the same way, it's also boot-compatible with mainline U-Boot,
   which stores U-Boot params in block 0 not block 16.

 - It's not quite compatible with systems that previously used NAND
   partitions to hold (filesystem) data.  The compatibilities are a
   bit different based on which kernel was used previously
     + Users of TI/MV kernels no longer see mtd2 "params"
       (mainline u-boot env is in a different place)
	* Filesystem is now mtd2 ... vs mtd3
     + Users of GIT kernels now see mtd0 and mtd1 partitions
	* Filesystem partition starts 640 KBytes earlier
	* Filesystem is now mtd2 ... vs mtd0
     * Linux now *uses* the flash-resident BBT
	* Removes annoying slowdown/hiccup during boot
	* Potentially ~64KB less space available with TI/MV kernels

If you *used* NAND partitions from Linux, there is no solution that's
fully compatible with all previous kernels in those respects ... ergo
this "best compromise".  It'd be good to back back up the filesystem
data; or, carry your own backwards-compatibility patch for awhile.

Subject: Btrfs: fix acl caching

Linus noticed the btrfs code to cache acls wasn't properly caching
a NULL acl when the inode didn't have any acls.  This meant the common
case of no acls resulted in expensive btree searches every time the
kernel checked permissions (which is quite often).

This is a modified version of Linus' original patch:

Properly set initial acl fields to BTRFS_ACL_NOT_CACHED in the inode.
This forces an acl lookup when permission checks are done.

Fix btrfs_get_acl to avoid lookups and locking when the inode acls fields
are set to null.

Fix btrfs_get_acl to use the right return value from __btrfs_getxattr
when deciding to cache a NULL acl.  It was storing a NULL acl when
__btrfs_getxattr return -ENOENT, but __btrfs_getxattr was actually returning
-ENODATA for this case.

Subject: Btrfs: look for acls during btrfs_read_locked_inode

This changes btrfs_read_locked_inode() to peek ahead in the btree for acl items.
If it is certain a given inode has no acls, it will set the in memory acl
fields to null to avoid acl lookups completely.

-Tux is taking a three month sabbatical to work as a barber, so Tuz is
-standing in.  He's taken pains to ensure you'll hardly notice.
+This is the full-colour version of the currently unofficial Linux logo
+("currently unofficial" just means that there has been no paperwork and
+that I have not really announced it yet).  It was created by Larry Ewing,
+and is freely usable as long as you acknowledge Larry as the original
+artist. 
+
+Note that there are black-and-white versions of this available that
+scale down to smaller sizes and are better for letterheads or whatever
+you want to use it for: for the full range of logos take a look at
+Larry's web-page:

We need to check only if the WM8350 is master and only when starting
the stream so if either is not true then we can skip the check.

Subject: RDMA/nes: Correct CDR loop filter setting for port 1

In commit 1b949324 ("RDMA/nes: Fix SFP+ PHY initialization") there is
a mistake in the clean up code that removed port 1 CDR loop filter
settings for 10G cards other than CX4.  Put the correct setting back
for appropriate PHY types.

Subject: RDMA/nes: Fix hang issues for large cluster dynamic connections

Running large cluster setup, we are hanging after many hours of
testing.  Fixing this required going over the code and making sure the
rexmit entry was properly removed based on the cm_node's state and
packet received.  Also when receiving a FIN packet, check seq# and
make sure there were no errors before calling handle_fin().

Following are the changes done in nes_cm.c:

* handle_ack_pkt() needs to return error value, so in case of error,
  handle_fin() is not called. Some cleanup done while going over the code.

* handle_rst_pkt(), handling of cm_node's NES_CM_STATE_LAST_ACK is missing.

* process_packet(), in case of FIN only packet is received, call
  check_seq() before processing.

* in handle_fin_pkt(), we are calling cleanup_retrans_entry() for all
  conditions, even if the packets need to be dropped.

Subject: RDMA/nes: Fix error path in nes_accept()

If reg_phys_mem() fails, we need to free memory allocated for MPA
frame with private data before returning the error. Also move
nes_add_ref() after the reg_phys_mem() is successful.

Rather than adding .ref.text to the powerpc linker script so that we
can use __REF on the powerpc architecture, it seems simpler to switch
to using the generic TEXT_TEXT macro.

Subject: Remove unused support code for refok sections.

The old refok sections

  .text.init.refok
  .data.init.refok
  .exit.text.refok

have been deprecated since commit
312b1485fb509c9bc32eda28ad29537896658cb8.  After the other patches in
this patch series nothing is put in these sections, so clean things up
by eliminating all the remaining references to them.

Subject: powerpc: ppc32 needs elf_read_implies_exec()

On ppc64 we implemented elf_read_implies_exec() for 32-bit binaries
because old toolchains had bugs where they didn't mark program
segments executable that needed to be.  For some reason we didn't do
this on ppc32 builds.  This hadn't been an issue until commit 8d30c14c
("powerpc/mm: Rework I$/D$ coherency (v3)"), which had as a side
effect that we are now enforcing execute permissions to some extent on
32-bit 4xx and Book E processors.

This fixes it by defining elf_read_implies_exec on 32-bit to turn on
the read-implies-exec behaviour on programs that are sufficiently old
that they don't have a PT_GNU_STACK program header.

Subject: powerpc/cell: Select PCI for IBM_CELL_BLADE AND CELLEB

Currently PPC_CELL_NATIVE selects PPC_OF_PLATFORM_PCI, but does not
select PCI. This can lead to a config with the former and the latter
disabled, which does not build.

To fix this PPC_CELL_NATIVE should select PCI. However, that would
force PCI on for QPACE, which also selects PPC_CELL_NATIVE. So
instead move the select of PPC_OF_PLATFORM_PCI and PCI under both
IBM_CELL_BLADE and CELLEB.

Subject: ALSA: pcm core - Avoid jiffies check for devices with BATCH flag

The hardware devices with SNDRV_PCM_INFO_BATCH flag can't give the
precise current position.  And such hardwares have often big FIFO
in addition to the ring buffer, and it screws up the jiffies check
in pcm_lib.c.

This patch adds a simple check of info flag so that the driver skips
the jiffies check in snd_pcm_period_elapsed() when BATCH flag is set.

Destroy bdi on error in fuse_fill_super().

This was an omission from commit 26c3679101dbccc054dcf370143941844ba70531
"fuse: destroy bdi on umount", which moved the bdi_destroy() call from
fuse_conn_put() to fuse_put_super().

Subject: Input: bcm5974 - add quad-finger tapping

The integrated button on the new unibody Macbooks presents a need to
report explicit four-finger actions. Evidently, the finger pressing
the button is also touching the trackpad, so in order to fully support
three-finger actions, the driver must be able to report four-finger
actions. This patch adds a new button, BTN_TOOL_QUADTAP, which
achieves this.

Subject: Input: bcm5974 - Add support for the Macbook 5 (Unibody)

This patch adds support for the new unibody Macbook, with physically
integrated button and trackpad. Since the integrated button changes
the logic for touch-and-click, a device capability bit mask is now
reported in input_id.version, which can be picked up by user space
via a EVIOCGID call.

+BCM5974 Driver (bcm5974)
+------------------------
+	Copyright (C) 2008-2009	Henrik Rydberg <rydberg@euromail.se>
+
+The USB initialization and package decoding was made by Scott Shawcroft as
+part of the touchd user-space driver project:
+	Copyright (C) 2008	Scott Shawcroft (scott.shawcroft@gmail.com)
+
+The BCM5974 driver is based on the appletouch driver:
+	Copyright (C) 2001-2004	Greg Kroah-Hartman (greg@kroah.com)
+	Copyright (C) 2005	Johannes Berg (johannes@sipsolutions.net)
+	Copyright (C) 2005	Stelian Pop (stelian@popies.net)

+	Copyright (C) 2005	Michael Hanselmann (linux-kernel@hansmi.ch)
+	Copyright (C) 2006	Nicolas Boichat (nicolas@boichat.ch)
+
+This driver adds support for the multi-touch trackpad on the new Apple
+Macbook Air and Macbook Pro laptops. It replaces the appletouch driver on
+those computers, and integrates well with the synaptics driver of the Xorg
+system.
+
+Known to work on Macbook Air, Macbook Pro Penryn and the new unibody
+Macbook 5 and Macbook Pro 5.
+
+Usage
+-----
+
+The driver loads automatically for the supported usb device ids, and
+becomes available both as an event device (/dev/input/event*) and as a
+mouse via the mousedev driver (/dev/input/mice).
+
+USB Race
+--------
+
+The Apple multi-touch trackpads report both mouse and keyboard events via
+different interfaces of the same usb device. This creates a race condition
+with the HID driver, which, if not told otherwise, will find the standard
+HID mouse and keyboard, and claim the whole device. To remedy, the usb
+product id must be listed in the mouse_ignore list of the hid driver.
+
+Debug output
+------------
+
+To ease the development for new hardware version, verbose packet output can
+be switched on with the debug kernel module parameter. The range [1-9]
+yields different levels of verbosity. Example (as root):
+
+echo -n 9 > /sys/module/bcm5974/parameters/debug
+
+tail -f /var/log/debug
+
+echo -n 0 > /sys/module/bcm5974/parameters/debug
+
+Trivia
+------
+
+The driver was developed at the ubuntu forums in June 2008 [1], and now has
+a more permanent home at bitmath.org [2].

Subject: Input: add detailed multi-touch finger data report protocol

In order to utilize the full power of the new multi-touch devices, a
way to report detailed finger data to user space is needed. This patch
adds a multi-touch (MT) protocol which allows drivers to report details
for an arbitrary number of fingers.

The driver sends a SYN_MT_REPORT event via the input_mt_sync() function
when a complete finger has been reported.

In order to stay compatible with existing applications, the data
reported in a finger packet must not be recognized as single-touch
events. In addition, all finger data must bypass input filtering,
since subsequent events of the same type refer to different fingers.

A set of ABS_MT events with the desired properties are defined. The
events are divided into categories, to allow for partial implementation.
The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and
ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked.
If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide
the size of the approaching finger. Anisotropy and direction may be
specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and
ABS_MT_ORIENTATION. Devices with more granular information may specify
general shapes as blobs, i.e., as a sequence of rectangular shapes
grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE
may be used to specify whether the touching tool is a finger or a pen.

  should that not be "spin_unlock_irqrestore()"?

Subject: regulator core: fix double-free in regulator_register() error path

During regulator registration, any error after device_register() will
cause a double-free on the struct regulator_dev 'rdev'.  The bug is in
drivers/regulator/core.c:regulator_register():

...
scrub:
	device_unregister(&rdev->dev);
clean:
	kfree(rdev);                           <---
	rdev = ERR_PTR(ret);
	goto out;
...

device_unregister() calls regulator_dev_release() which frees rdev.  The
subsequent kfree corrupts memory and causes some OMAP3 systems to oops on
boot in regulator_get().

Applies against 2.6.30-rc3.

Subject: regulator: Fix default constraints for fixed voltage regulators

Default voltage constraints were being provided for fixed voltage
regulator where board constraints were not provided but these constraints
used INT_MIN as the default minimum voltage which is not a valid value
since it is less than zero. Use 1uV instead.

Also set the default values we set in the constraints themselves since
otherwise the max_uV constraint we determine will not be stored in the
actual constraint strucutre and will therefore not be used.

Subject: hd: fix locking

hd dance around local irq and HD_IRQ enable without achieving much.
It ends up transferring data from irq handler with both local irq and
HD_IRQ disabled.  The only place it actually does something is while
transferring the first block of a request which it does with HD_IRQ
disabled but local irq enabled.

Unfortunately, the dancing is horribly broken from locking POV.  IRQ
and timeout handlers access block queue without grabbing the queue
lock and running the driver in SMP configuration crashes the whole
machine pretty quickly.

Remove meaningless irq enable/disable dancing and add proper locking
in issue, irq and timeout paths.

Subject: bio: fix memcpy corruption in bio_copy_user_iov()

st driver uses blk_rq_map_user() in order to just build a request out
of page frames. In this case, map_data->offset is a non zero value and
iov[0].iov_base is NULL. We need to increase nr_pages for that.

Subject: powerpc: Revert switch to TEXT_TEXT in linker script

Commit edada399 broke the build on 64-bit powerpc because it moved the
__ftr_alt_* sections of a file away from the .text section, causing
link failures due to relative conditional branch targets being too far
away from the branch instructions.  This happens on pretty much all
64-bit powerpc configs.

This change reverts commit edada399 while preserving the update from
the *.refok sections to .ref.text that has happened since.

Subject: mtd: Bug in m25p80.c during whole-chip erase

There is a logic error in "whole chip erase" for the m25p80 family.  If
the whole device is successfully erased, erase_chip() will return 0, and
the code will fall through to the "else" clause, and do sector-by-sector
erase in addition to the whole-chip erase.  This patch corrects that.

Also, the MAX_READY_WAIT_COUNT is insufficient for an m25p16 connected
to a 400 MHz powerpc.  Increasing it allows me to successfully program
the device on my board.

The pages allocated for the splice binary buffer did not initialize

was.

Subject: sched: account system time properly

Andrew Gallatin reported that IRQ and SOFTIRQ times were
sometime not reported correctly on recent kernels, and even
bisected to commit 457533a7d3402d1d91fbc125c8bd1bd16dcd3cd4
([PATCH] fix scaled & unscaled cputime accounting) as the first
bad commit.

Further analysis pointed that commit
79741dd35713ff4f6fd0eafd59fa94e8a4ba922d ([PATCH] idle cputime
accounting) was the real cause of the problem.

account_process_tick() was not taking into account timer IRQ
interrupting the idle task servicing a hard or soft irq.

On mostly idle cpu, irqs were thus not accounted and top or
mpstat could tell user/admin that cpu was 100 % idle, 0.00 %
irq, 0.00 % softirq, while it was not.

[ Impact: fix occasionally incorrect CPU statistics in top/mpstat ]

Subject: V4L/DVB (11561a): move media after i2c

Currently drivers/media drivers are linked very early - directly after
base, block, misc, and mfd and before ata, scsi, ide, input, firewire,
usb, and i2c. This breaks static build of video4linux drivers, that use
generic CPU i2c adapter drivers and the v4l2-subdev subsystem, because
during video4linux probing the v4l2-subdev core requires a struct
i2c_adapter context, which cannot be satisfied before the i2c subsystem is
initialised. Moving drivers/media after drivers/i2c fixes this problem.

The best way to trigger action is by submitting a patch:-) So, let's see
what comes out of it - on the one hand I don't see any reason why media
has to be linked this early, and nobody was able to give me one yesterday
as this problem has been discussed on linux-media, OTOH, maybe indeed it
would be better to move i2c the whole way up above media, but that'd be
much bigger of a change, I think.

Subject: V4L/DVB (11652): au0828: fix kernel oops regression on USB
 disconnect.

A regression was introduced in hg changeset 33810c734a0d, which resulted in
a kernel panic whenever the device was disconnected from USB.  The call to
4l2_device_register() was overwriting the pointer for usb_set_intfdata(), so
when au0828_usb_disconnect() was called, the usb_get_intfdata() returned a
pointer to the v4l2_device instead of the au0828_dev structure.

When the SQ is flushed, mark the flushed entries as not signaled so

The bug can cause the NFS/RDMA server to crash due to processing the

The problem here is that xfs_file_last_byte() does not acquire the
inode lock and can therefore race with another thread that is modifying
the extext list.  While xfs_bmap_last_offset() is trying to lookup
what was the last extent some extents were merged and the extent list
shrunk so the index we lookup is now beyond the end of the extent list
and potentially in a freed buffer.

Subject: xfs: a couple getbmap cleanups

 - reshuffle various conditionals for data vs attr fork to make the code
   more readable
 - do fine-grainded goto-based error handling
 - exit early from conditionals instead of keeping a long else branch around
 - allow kmem_alloc to fail

Subject: xfs: fix getbmap vs mmap deadlock

xfs_getbmap (or rather the formatters called by it) copy out the getbmap
structures under the ilock, which can deadlock against mmap.  This has
been reported via bugzilla a while ago (#717) and has recently also
shown up via lockdep.

So allocate a temporary buffer to format the kernel getbmap structures
into and then copy them out after dropping the locks.

A little problem with this is that we limit the number of extents we
can copy out by the maximum allocation size, but I see no real way
around that.

Subject: x86: gettimeofday() vDSO: fix segfault when tv == NULL

According to the gettimeofday(2) manual:

       If either tv or tz is NULL, the corresponding structure is not
       set or returned.

Since it is legal to give NULL as the tv argument, the code should make
sure tv is not NULL before trying to dereference it.

This issue manifests itself on x86_64 when vdso=0 is not on the kernel
command-line and libc uses the vDSO for gettimeofday() (e.g. glibc >=
2.7).  A simple reproducer:

  #include <stdio.h>
  #include <sys/time.h>

  int main(void)
  {
      struct timezone tz;

      gettimeofday(NULL, &tz);

      return 0;
  }

See http://bugs.debian.org/466491 for more details.

Subject: nls: add a nls_nullsize inline

It's possible for character sets to require a multi-byte null
string terminator. Add a helper function that determines the size
of the null terminator at runtime.

Subject: cifs: add new function to get unicode string length in bytes

Working in units of words means we do a lot of unnecessary conversion back
and forth. Standardize on bytes instead since that's more useful for
allocating buffers and such. Also, remove hostlen_fromUCS since the new
function has a similar purpose.

Subject: cifs: change CIFSSMBUnixQuerySymLink to use new helpers

Change CIFSSMBUnixQuerySymLink to use the new unicode helper functions.
Also change the calling conventions so that the allocation of the target
name buffer is done in CIFSSMBUnixQuerySymLink rather than by the caller.

Subject: [CIFS] Remove older session setup implementation

Two years ago, when the session setup code in cifs was rewritten and moved
to fs/cifs/sess.c, we were asked to keep the old code for a release or so
(which could be reenabled at runtime) since it was such a large change and
because the asn (SPNEGO) and NTLMSSP code was not rewritten and needed to
be. This was useful to avoid regressions, but is long overdue to be removed.
Now that the Kerberos (asn/spnego) code is working in fs/cifs/sess.c,
and the NTLMSSP code moved (NTLMSSP blob setup be rewritten with the
next patch in this series) quite a bit of dead code from fs/cifs/connect.c
now can be removed.

This old code should have been removed last year, but the earlier krb5
patches did not move/remove the NTLMSSP code which we had asked to
be done first.  Since no one else volunteered, I am doing it now.

It is extremely important that we continue to examine the documentation
for this area, to make sure our code continues to be uptodate with
changes since Windows 2003.

Subject: ide-cd: fix REQ_QUIET tests in cdrom_decode_status

Original patch (dfa4411cc3a690011cab90e9a536938795366cf9) was buggy.
This is a more proper fix which introduces blk_rq_quiet() macro
alleviating the need for dumb, too short caching variables.

Thanks to Helge Deller and Bart for debugging this.

+Multi-touch (MT) Protocol
+-------------------------
+	Copyright (C) 2009	Henrik Rydberg <rydberg@euromail.se>
+
+
+Introduction
+------------
+
+In order to utilize the full power of the new multi-touch devices, a way to
+report detailed finger data to user space is needed. This document
+describes the multi-touch (MT) protocol which allows kernel drivers to
+report details for an arbitrary number of fingers.
+
+
+Usage
+-----
+
+Anonymous finger details are sent sequentially as separate packets of ABS
+events. Only the ABS_MT events are recognized as part of a finger
+packet. The end of a packet is marked by calling the input_mt_sync()
+function, which generates a SYN_MT_REPORT event. The end of multi-touch
+transfer is marked by calling the usual input_sync() function.
+
+A set of ABS_MT events with the desired properties is defined. The events
+are divided into categories, to allow for partial implementation.  The
+minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and
+ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked.  If the
+device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size
+of the approaching finger. Anisotropy and direction may be specified with
+ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with
+more granular information may specify general shapes as blobs, i.e., as a
+sequence of rectangular shapes grouped together by an
+ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify
+whether the touching tool is a finger or a pen or something else.
+
+
+Event Semantics
+---------------
+
+The word "contact" is used to describe a tool which is in direct contact
+with the surface. A finger, a pen or a rubber all classify as contacts.
+
+ABS_MT_TOUCH_MAJOR
+
+The length of the major axis of the contact. The length should be given in
+surface units. If the surface has an X times Y resolution, the largest
+possible value of ABS_MT_TOUCH_MAJOR is sqrt(X^2 + Y^2), the diagonal.
+
+ABS_MT_TOUCH_MINOR
+
+The length, in surface units, of the minor axis of the contact. If the
+contact is circular, this event can be omitted.
+
+ABS_MT_WIDTH_MAJOR
+
+The length, in surface units, of the major axis of the approaching
+tool. This should be understood as the size of the tool itself. The
+orientation of the contact and the approaching tool are assumed to be the
+same.
+
+ABS_MT_WIDTH_MINOR
+
+The length, in surface units, of the minor axis of the approaching
+tool. Omit if circular.
+
+The above four values can be used to derive additional information about
+the contact. The ratio ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR approximates
+the notion of pressure. The fingers of the hand and the palm all have
+different characteristic widths [1].
+
+ABS_MT_ORIENTATION
+
+The orientation of the ellipse. The value should describe half a revolution
+clockwise around the touch center. The scale of the value is arbitrary, but
+zero should be returned for an ellipse aligned along the Y axis of the
+surface. As an example, an index finger placed straight onto the axis could
+return zero orientation, something negative when twisted to the left, and
+something positive when twisted to the right. This value can be omitted if
+the touching object is circular, or if the information is not available in
+the kernel driver.
+
+ABS_MT_POSITION_X
+
+The surface X coordinate of the center of the touching ellipse.
+
+ABS_MT_POSITION_Y
+
+The surface Y coordinate of the center of the touching ellipse.
+
+ABS_MT_TOOL_TYPE
+
+The type of approaching tool. A lot of kernel drivers cannot distinguish
+between different tool types, such as a finger or a pen. In such cases, the
+event should be omitted. The protocol currently supports MT_TOOL_FINGER and
+MT_TOOL_PEN [2].
+
+ABS_MT_BLOB_ID
+
+The BLOB_ID groups several packets together into one arbitrarily shaped
+contact. This is a low-level anonymous grouping, and should not be confused
+with the high-level contactID, explained below. Most kernel drivers will
+not have this capability, and can safely omit the event.
+
+
+Finger Tracking
+---------------
+
+The kernel driver should generate an arbitrary enumeration of the set of
+anonymous contacts currently on the surface. The order in which the packets
+appear in the event stream is not important.
+
+The process of finger tracking, i.e., to assign a unique contactID to each
+initiated contact on the surface, is left to user space; preferably the
+multi-touch X driver [3]. In that driver, the contactID stays the same and
+unique until the contact vanishes (when the finger leaves the surface). The
+problem of assigning a set of anonymous fingers to a set of identified
+fingers is a euclidian bipartite matching problem at each event update, and
+relies on a sufficiently rapid update rate.
+
+Notes
+-----
+
+In order to stay compatible with existing applications, the data
+reported in a finger packet must not be recognized as single-touch
+events. In addition, all finger data must bypass input filtering,
+since subsequent events of the same type refer to different fingers.
+
+The first kernel driver to utilize the MT protocol is the bcm5974 driver,
+where examples can be found.
+
+[1] With the extension ABS_MT_APPROACH_X and ABS_MT_APPROACH_Y, the
+difference between the contact position and the approaching tool position
+could be used to derive tilt.
+[2] The list can of course be extended.
+[3] The multi-touch X driver is currently in the prototyping stage. At the
+time of writing (April 2009), the MT protocol is not yet merged, and the
+prototype implements finger matching, basic mouse support and two-finger
+scrolling. The project aims at improving the quality of current multi-touch
+functionality available in the synaptics X driver, and in addition
+implement more advanced gestures.

Subject: [CIFS] rename cifs_strndup to cifs_strndup_from_ucs

In most cases, cifs_strndup is converting from Unicode (UCS2 / UTF-32) to
the configured local code page for the Linux mount (usually UTF8), so
Jeff suggested that to make it more clear that cifs_strndup is doing
a conversion not just memory allocation and copy, rename the function
to including "from_ucs" (ie Unicode)

Subject: [ARM] 5487/1: ARM errata: Stale prediction on replaced interworking
 branch

This patch adds the workaround for the 430973 Cortex-A8 (r1p0..r1p2)
erratum. The BTAC/BTB is now flushed at every context switch.

This patch is a workaround for the 460075 Cortex-A8 (r2p0) erratum. It
configures the L2 cache auxiliary control register so that the Write

Subject: ocfs2: Fix a missing credit when deleting from indexed directories.

The ocfs2 directory index updates two blocks when we remove an entry -
the dx root and the dx leaf.  OCFS2_DELETE_INODE_CREDITS was only
accounting for the dx leaf.  This shows up when ocfs2_delete_inode()
runs out of credits in jbd2_journal_dirty_metadata() at
"J_ASSERT_JH(jh, handle->h_buffer_credits > 0);".

The test that caught this was running dirop_file_racer from the
ocfs2-test suite with a 250-character filename PREFIX.  Run on a 512B
blocksize, it forces the orphan dir index to grow large enough to
trigger.

Subject: drm/i915: save/restore fence registers across suspend/resume

This makes software fallbacks not do tiling wrong on i965 and later after
resume. It also should fix 945 performance reduction after resume which
would have disabled tiling without causing any visible effect.

Subject: cifs: fix length handling in cifs_get_name_from_search_buf

The earlier patch to move this code to use the new unicode helpers
assumed that the filename strings would be null terminated. That's not
always the case.

Instead of passing "max_len" to the string converter, pass "min(len,
max_len)", which makes it do the right thing while still keeping the
parser confined to the response. Also fix up the prototypes of this
function and the callers so that max_len is unsigned (like len is).

Subject: powerpc adjust oprofile_cpu_type version 3

Oprofile is changing the naming it is using for the compatibility modes.
Instead of having compat-power<x>, oprofile will go to family naming
convention and use ibm-compat-v<x>.  Currently only ibm-compat-v1 will
be defined.
The notion of compatibility events just started with POWER6. So there is
no way that any other tool could exist that is using these
oprofile_cpu_type strings we want to change.

Subject: powerpc: Fix setting of oprofile cpu type

commit 2657dd4e301d4841ed67a4fac7d145ad8f3e1b28 introduced a
bug where we would now always override the "real" oprofile CPU
type with the "compatible" one provided by a pseudo-PVR in the
device-tree which is incorrect and breaks oprofile on all current
configs since the "compatible" ones aren't yet recognized.

This fixes it.

Subject: [CIFS] Remove sparse endian warnings

Removes two sparse CHECK_ENDIAN warnings from Jeffs earlier patch,
and removes the dead readlink code (after noting where in
findfirst we will need to add something like that in the future
to handle the newly discovered unexpected error on FindFirst of NTFS symlinks.

Subject: kbuild: fix Module.markers permission error under cygwin

While building the kernel, we end-up calling modpost with -K and -M
options for the same file (Modules.markers).  This is resulting in
modpost's main function calling read_markers() and then write_markers() on
the same file.

We then have read_markers() mmap'ing the file, and writer_markers()
opening that same file for writing.

The issue is that read_markers() exits without munmap'ing the file and is
as a matter holding a reference on Modules.markers.  When write_markers()
is opening that very same file for writing, we still have a reference on
it and cygwin (Windows?) is then making fopen() fail with EPERM.

Calling release_file() before exiting read_markers() clears that reference
(and memory leak) and fopen() then succeeds.

Tested on both cygwin (1.3.22) and Linux.  Also ran modpost within
valgrind on Linux to make sure that the munmap'ed file was not accessed
after read_markers()

Subject: kbuild: fix scripts/setlocalversion with git

When using trees like wireless-testing, which have untagged tags,
scripts/setlocalversion does not display any git indication for
localversion.

This patch fixes it: If git is available, but no usable tag is found,
it uses -g${head}. It skips the detection of unanottated tags via
git name-rev.

Subject: kbuild, modpost: Check the section flags, to catch missing "ax"/"aw"

When you put
  .section ".foo"
in an assembly file instead of
  .section "foo", "ax"
, one of the possible symptoms is that modpost will see an
ld-generated section name ".foo.1" in section_rel() or section_rela().
But this heuristic has two problems: it will miss a bad section that
has no relocations, and it will incorrectly flag many gcc-generated
sections as bad when compiling with -ffunction-sections
-fdata-sections.

On mips it fixes a lot of bogus warnings with gcc 4.4.0 lije this one:
WARNING: crypto/cryptd.o (.text.T.349): unexpected section name.

So instead of checking whether the section name matches a particular
pattern, we directly check for a missing SHF_ALLOC in the section
flags.

This reverts commit 044d408409cc4e1bc75c886e27ca85c270db104c.

The commit added a warning when handle_IRQ_event() is called outside
of hard interrupt context. This breaks the generic tasklet based
interrupt resend mechanism which is used when the hardware has no way
to retrigger the interrupt. So we get a warning for a use case which
is correct and worked for years. Remove it.

Subject: microblaze: Storage class should be before const qualifier

The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the
beginning of the declaration specifiers in a declaration is an
obsolescent feature.

Subject: [CIFS] Fix endian conversion of vcnum field

When multiply mounting from the same client to the same server, with
different userids, we create a vcnum which should be unique if
possible (this is not the same as the smb uid, which is the handle
to the security context).  We were not endian converting additional
(beyond the first which is zero) vcnum properly.

Subject: x86: initialize io_bitmap_base on 32bit

commit db949bba3c7cf2e664ac12e237c6d4c914f0c69d (x86-32: use non-lazy
io bitmap context switching) broke ioperm for 32bit because it removed
the lazy initialization of io_bitmap_base and did not set it to the
real bitmap offset.

[ Impact: fix non-working sys_ioperm() on 32-bit kernels ]

Subject: HID: fix oops in hid_check_keys_pressed()

If the device is not claimed by hid-input (i.e devices driver by userspace
hiddev/hidraw-based drivers, or completely detached from HID
and driver by libusb), we must not check the hid->inptus, as it
is not guaranteed to be initialized, as this is performed only for devices
handled by hid-input.

Subject: clockevents: prevent endless loop in tick_handle_periodic()

tick_handle_periodic() can lock up hard when a one shot clock event
device is used in combination with jiffies clocksource.

Avoid an endless loop issue by requiring that a highres valid
clocksource be installed before we call tick_periodic() in a loop when
using ONESHOT mode. The result is we will only increment jiffies once
per interrupt until a continuous hardware clocksource is available.

Without this, we can run into a endless loop, where each cycle through
the loop, jiffies is updated which increments time by tick_period or
more (due to clock steering), which can cause the event programming to
think the next event was before the newly incremented time and fail
causing tick_periodic() to be called again and the whole process loops
forever.

[ Impact: prevent hard lock up ]

Subject: m32r: build fix for __stringify macro

This patch fixes the following build error of 2.6.30-rc3-git2:

      AS      arch/m32r/kernel/head.o
    In file included from /include/linux/init.h:7,
                     from /arch/m32r/kernel/head.S:11:
    /include/linux/stringify.h:9: error: syntax error in macro parameter list
    /include/linux/stringify.h:10: error: syntax error in macro parameter list

This build error was caused at __HEAD macro in arch/m32r/kernel/head.S,
which uses __stringify() macro.

Remove -traditional option from EXTRA_AFLAGS for the m32r,
because the __stringify() macro depends on the gcc's variadic macro
extension function, due to commit:

    Make __stringify support variable argument macros too

Replace #x with __stringify(x).
Also, #ifndef __STR is removed and undefine __STR macro at the beginning.

The __STR() macro is still remained, because the assembler.h might be
included from assembly codes as well as C codes.

Subject: acpica: validate package element more carefully in
 acpi_rs_get_pci_routing_table_length

acpi_rs_get_pci_routing_table_length is not performing sufficient
validation on the package returned from _PRT.  It assumes a package of
packages and fails/faults if this is not the case.

We should validate each subpackage when extracted from the parent
package, and not accept objects of the wrong type, since that will just
cause the scanning to fail (likely with a kernel oops).

This can only happen with a serious BIOS bug, and is accompanied by a
warning something like this:

  ACPI Warning (nspredef-0949): \_SB_.PCI0.PEG4._PRT: Return Package type mismatch at index 0 - found Integer, expected Package [20090320]

If the cgroup callback fails make sure to unlock AND release the page
reference which was taken by lookup_swap_cach(), or we leak the reference.

Subject: atomic: fix atomic_long_cmpxchg/xchg for 64 bit architectures

On a linux-next allyesconfig build:

kernel/trace/ring_buffer.c:1726:
	warning: passing argument 1 of 'atomic_cmpxchg' from incompatible pointer type
linux-next/arch/s390/include/asm/atomic.h:112:
	note: expected 'struct atomic_t *' but argument is of type 'struct atomic64_t *'

atomic_long_cmpxchg and atomic_long_xchg are incorrectly defined for 64
bit architectures.  They should be mapped to the atomic64_* variants.

Subject: mm: close page_mkwrite races

Change page_mkwrite to allow implementations to return with the page
locked, and also change it's callers (in page fault paths) to hold the
lock until the page is marked dirty.  This allows the filesystem to have
full control of page dirtying events coming from the VM.

Rather than simply hold the page locked over the page_mkwrite call, we
call page_mkwrite with the page unlocked and allow callers to return with
it locked, so filesystems can avoid LOR conditions with page lock.

The problem with the current scheme is this: a filesystem that wants to
associate some metadata with a page as long as the page is dirty, will
perform this manipulation in its ->page_mkwrite.  It currently then must
return with the page unlocked and may not hold any other locks (according
to existing page_mkwrite convention).

In this window, the VM could write out the page, clearing page-dirty.  The
filesystem has no good way to detect that a dirty pte is about to be
attached, so it will happily write out the page, at which point, the
filesystem may manipulate the metadata to reflect that the page is no
longer dirty.

It is not always possible to perform the required metadata manipulation in
->set_page_dirty, because that function cannot block or fail.  The
filesystem may need to allocate some data structure, for example.

And the VM cannot mark the pte dirty before page_mkwrite, because
page_mkwrite is allowed to fail, so we must not allow any window where the
page could be written to if page_mkwrite does fail.

This solution of holding the page locked over the 3 critical operations
(page_mkwrite, setting the pte dirty, and finally setting the page dirty)
closes out races nicely, preventing page cleaning for writeout being
initiated in that window.  This provides the filesystem with a strong
synchronisation against the VM here.

- Sage needs this race closed for ceph filesystem.
- Trond for NFS (http://bugzilla.kernel.org/show_bug.cgi?id=12913).
- I need it for fsblock.
- I suspect other filesystems may need it too (eg. btrfs).
- I have converted buffer.c to the new locking. Even simple block allocation
  under dirty pages might be susceptible to i_size changing under partial page
  at the end of file (we also have a buffer.c-side problem here, but it cannot
  be fixed properly without this patch).
- Other filesystems (eg. NFS, maybe btrfs) will need to change their
  page_mkwrite functions themselves.

[ This also moves page_mkwrite another step closer to fault, which should
  eventually allow page_mkwrite to be moved into ->fault, and thus avoiding a
  filesystem calldown and page lock/unlock cycle in __do_fault. ]

/proc/pid/pagemap") was to force reads of /proc/pid/pagemap to be a
multiple of 8 bytes, but now it allows to read 0 bytes, which actually
puts some data to user's buffer.  According to POSIX, if count is zero,
read() should return zero and has no other results.

Subject: memcg: fix mem_cgroup_shrink_usage()

Current mem_cgroup_shrink_usage() has two problems.

1. It doesn't call mem_cgroup_out_of_memory and doesn't update
   last_oom_jiffies, so pagefault_out_of_memory invokes global OOM.

2. Considering hierarchy, shrinking has to be done from the
   mem_over_limit, not from the memcg which the page would be charged to.

mem_cgroup_try_charge_swapin() does all of these things properly, so we
use it and call cancel_charge_swapin when it succeeded.

The name of "shrink_usage" is not appropriate for this behavior, so we
change it too.

Subject: vgacon: return the upper half of 512 character fonts

Uwe Geuder noted that he gets random bitmaps on a text console if he tried
to type extended characters (like the e acute).  For him everything above
unicode 0xa0 was corrupted.

After some digging there seems to be a little culprit in vgacon since the
beginning of ages (well git).  The function vgacon_font_get will store the
number of characters correctly in font->charcount but then calls to
vgacon_do_font_op(..., 0, 0).  Which means only the lower 256 characters
are actually stored to the fontdata.  The rest is left untouched.  So the
next time that saved data is used, the garbled font appears.  This happens
on every switch between text consoles.

Subject: alpha: titan and marvel build fixes

These platforms got broken after u64 => 'long long' conversion.

Apparently that change was compile-tested with 'make allmodconfig', but it
doesn't include systems that depend on !ALPHA_LEGACY_START_ADDRESS.

Subject: alpha: exception table sorting

Exception fixups for sections other than .text (like one in futex_init())
break the natural ordering of fixup entries, so sorting is required.

Without that the result of the exception table search depends on phase of
the moon.

Subject: alpha: binfmt_aout fix

This fixes the problem introduced by commit 3bfacef412 (get rid of
special-casing the /sbin/loader on alpha): osf/1 ecoff binary segfaults
when binfmt_aout built as module.  That happens because aout binary
handler gets on the top of the binfmt list due to late registration, and
kernel attempts to execute the binary without preparatory work that must
be done by binfmt_loader.

Fixed by changing the registration order of the default binfmt handlers
using list_add_tail() and introducing insert_binfmt() function which
places new handler on the top of the binfmt list.  This might be generally
useful for installing arch-specific frontends for default handlers or just
for overriding them.

Subject: of: make of_(un)register_platform_driver common code

Some drivers using of_register_platform_driver() wrapper break on sparc
because the wrapper isn't in the header file.  This patch moves it from
Microblaze and PowerPC implementations and makes it common code.

Fixes this sparc64 allmodconfig build error (at least):

drivers/leds/leds-gpio.c: In function `gpio_led_init':
drivers/leds/leds-gpio.c:295: error: implicit declaration of function `of_register_platform_driver'
drivers/leds/leds-gpio.c: In function `gpio_led_exit':

Subject: mm: fix Committed_AS underflow on large NR_CPUS environment

Because NR_CPUS can be greater than 1000 and meminfo_proc_show() does
not check for underflow.

But NR_CPUS proportional isn't good calculation.  In general,
possibility of lock contention is proportional to the number of online
cpus, not theorical maximum cpus (NR_CPUS).

The current kernel has generic percpu-counter stuff.  using it is right
way.  it makes code simplify and percpu_counter_read_positive() don't
make underflow issue.

Subject: kernel-doc: restrict syntax for private: and public:

scripts/kernel-doc can (incorrectly) delete struct members that are
surrounded by /* ...  */ <struct members> /* ...  */ if there is a /*
private: */ comment in there somewhere also.

Fix that by making the "/* private:" only allow whitespace between /* and
"private:", not anything/everything in the world.

This fixes some erroneous kernel-doc warnings that popped up while
processing include/linux/usb/composite.h.

Subject: ibft: fix the display of a few fields in the NIC attribute structure
 in sysfs

Fix the display of a few fields in the iBFT NIC attribute structure in
sysfs.

Ensure that, if the DHCP IP address and the subnet mask for the interface
is present in the iBFT NIC structure, the corresponding entries are
created in sysfs tree for the device.  This would hence create the
additional entries in the tree based on the iBFT table and would not
delete any existing entries.

to supply device information.  On systems without OF, this comes from
a flattened device tree blob.  This blob is usually generated by dtc,
a tool which compiles a text description of the device tree into the
flattened format used by the kernel.  Sometimes, the bootwrapper makes
small changes to the pre-compiled device tree blob (e.g. filling in
the size of RAM).  To do this it uses the libfdt library.

Because these are only used on powerpc, the code for both these tools
is included under arch/powerpc/boot (these were imported and are
periodically updated from the upstream dtc tree).

However, the microblaze architecture, currently being prepared for
merging to mainline also uses dtc to produce device tree blobs.  A few
other archs have also mentioned some interest in using dtc.
Therefore, this patch moves dtc and libfdt from arch/powerpc into
scripts, where it can be used by any architecture.

The vast bulk of this patch is a literal move, the rest is adjusting
the various Makefiles to use dtc and libfdt correctly from their new
locations.

Subject: [CIFS] NTLMSSP reenabled after move from connect.c to sess.c

The NTLMSSP code was removed from fs/cifs/connect.c and merged
(75% smaller, cleaner) into fs/cifs/sess.c

As with the old code it requires that cifs be built with
CONFIG_CIFS_EXPERIMENTAL, the /proc/fs/cifs/Experimental flag
must be set to 2, and mount must turn on extended security
(e.g. with sec=krb5).

Although NTLMSSP encapsulated in SPNEGO is not enabled yet,
"raw" ntlmssp is common and useful in some cases since it
offers more complete security negotiation, and is the
default way of negotiating security for many Windows systems.
SPNEGO encapsulated NTLMSSP will be able to reuse the same
code.

Subject: kbuild, modpost: fix unexpected non-allocatable section when cross
 compiling

The missing TO_NATIVE(sechdrs[i].sh_flags) was causing many
unexpected non-allocatable section warnings when cross-compiling
for an architecture with a different endianness.

Fix endianness of all the fields in the ELF header and
section headers, not just some of them so we are not
hit by this anohter time.

Subject: kbuild, modpost: fix "unexpected non-allocatable" warning with SUSE
 gcc

Jean reported that he saw one warning for each module like the one below:
WARNING: arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.o (.comment.SUSE.OPTs): unexpected non-allocatable section.

The warning appeared with the improved version of the
check of the flags in the sections.

That check already ignored sections named ".comment" - but SUSE store
additional info in the comment section and has named it in a SUSE
specific way. Therefore modpost failed to ignore the section.

The fix is to extend the pattern so we ignore all sections
that start with the name ".comment.".

Subject: kbuild, modpost: fix unexpected non-allocatable warning with mips

mips emit the following debug sections:
.mdebug* and .pdr

They were included in the check for non-allocatable section
and caused modpost to warn.

Manuel Lauss suggested to fix this by adding the relevant
sections to the list of sections we do not check.

Subject: x86: show number of core_siblings instead of thread_siblings in
 /proc/cpuinfo

Commit 7ad728f98162cb1af06a85b2a5fc422dddd4fb78
(cpumask: x86: convert cpu_sibling_map/cpu_core_map to cpumask_var_t)
changed the output of /proc/cpuinfo for siblings:

Example on an AMD Phenom:

  physical id   : 0
  siblings : 1
  core id	   : 3
  cpu cores  : 4

Before that commit it was:

  physical id	: 0
  siblings : 4
  core id	   : 3
  cpu cores  : 4

Instead of cpu_core_mask it now uses cpu_sibling_mask to count siblings.
This is due to the following hunk of above commit:

|                  seq_printf(m, "apicid\t\t: %d\n", c->apicid);

This was a mistake, because the impact line shows that this side-effect
was not anticipated:

   Impact: reduce per-cpu size for CONFIG_CPUMASK_OFFSTACK=y

So revert the respective hunk to restore the old behavior.

Subject: proc: avoid information leaks to non-privileged processes

By using the same test as is used for /proc/pid/maps and /proc/pid/smaps,
only allow processes that can ptrace() a given process to see information
that might be used to bypass address space layout randomization (ASLR).
These include eip, esp, wchan, and start_stack in /proc/pid/stat as well
as the non-symbolic output from /proc/pid/wchan.

ASLR can be bypassed by sampling eip as shown by the proof-of-concept
code at http://code.google.com/p/fuzzyaslr/ As part of a presentation
(http://www.cr0.org/paper/to-jt-linux-alsr-leak.pdf) esp and wchan were
also noted as possibly usable information leaks as well.  The
start_stack address also leaks potentially useful information.

Subject: selinux: Fix send_sigiotask hook

The CRED patch incorrectly converted the SELinux send_sigiotask hook to
use the current task SID rather than the target task SID in its
permission check, yielding the wrong permission check.  This fixes the
hook function.  Detected by the ltp selinux testsuite and confirmed to
correct the test failure.

From 4ccc28f725bc2b7b0a3bc27e9c15f4eaf63fb812 Mon Sep 17 00:00:00 2001
From: Roel Kluin
Date: Tue, 5 May 2009 08:39:24 +0200
Subject: i2c: Timeouts off by 1

with while (timeout++ < MAX_TIMEOUT); timeout reaches MAX_TIMEOUT + 1
after the loop, so the tests below are off by one.

Subject: i2c-algo-bit: Fix timeout test

When fetching DDC using i2c algo bit, we were often seeing timeouts
before getting valid EDID on a retry. The VESA spec states 2ms is the
DDC timeout, so when this translates into 1 jiffie and we are close
to the end of the time period, it could return with a timeout less than
2ms.

Change this code to use time_after instead of time_after_eq.

Subject: i2c-algo-pca: Let PCA9564 recover from unacked data byte (state 0x30)

Currently, the i2c-algo-pca driver does nothing if the chip enters state
0x30 (Data byte in I2CDAT has been transmitted; NOT ACK has been
received).  Thus, the i2c bus connected to the controller gets stuck
afterwards.

I have seen this kind of error on a custom board in certain load
situations most probably caused by interference or noise.

A possible reaction is to let the controller generate a STOP condition.
This is documented in the PCA9564 data sheet (2006-09-01) and the same
is done for other NACK states as well.

Further, state 0x38 isn't handled completely, either. Try to do another
START in this case like the data sheet says. As this couldn't be tested,
I've added a comment to try to reset the chip if the START doesn't help
as suggested by Wolfram Sang.

Subject: MXC: remove BUG_ON in interrupt handler

On i.MX31 I sometimes get spurious interrupts. There is no need
to crash the whole system when this happens. Instead, silently
ignore it.

Subject: mx27ads: move PBC mapping out of vmalloc space

Before this patch I got the following line in my dmesg:

	[    0.000000] BUG: mapping for 0xd4000000 at 0xeb000000 overlaps vmalloc space

VMALLOC_END is 0xf4000000 and there are the following other mappings
defined for mx27ads:

	(0xa0500000,+0x00001000) maps to 0xffff0000
	(0x10000000,+0x00100000) maps to 0xf4000000
	(0x80000000,+0x00100000) maps to 0xf4100000
	(0xd8000000,+0x00100000) maps to 0xf4200000

So map PBC to 0xf4300000.

Subject: ipu_idmac: Use disable_irq_nosync() from within irq handlers.

disable_irq() should wait for all running handlers to complete
before returning.  As such, if it's used to disable an interrupt
from that interrupt's handler it will deadlock.  This replaces
the dangerous instances with the _nosync() variant which doesn't
have this problem.

Note the 2 handlers in question are only used #ifdef DEBUG so
I imagine these code paths don't get hit often.

Subject: PCI: Fix pci-e port driver slot_reset bad default return value

When an upstream port reports an AER error to root port, kernel
starts error recovery procedures. The default return value of
function pcie_portdrv_slot_reset is PCI_ERS_RESULT_NONE. If all
port service drivers of the downstream port under the upstream
port have no slot_reset method in pci_error_handlers, AER recovery
would stop without resume. Below patch against 2.6.30-rc3 fixes it.

Subject: Ignore madvise(MADV_WILLNEED) for hugetlbfs-backed regions

madvise(MADV_WILLNEED) forces page cache readahead on a range of memory
backed by a file.  The assumption is made that the page required is
order-0 and "normal" page cache.

On hugetlbfs, this assumption is not true and order-0 pages are
allocated and inserted into the hugetlbfs page cache.  This leaks
hugetlbfs page reservations and can cause BUGs to trigger related to
corrupted page tables.

This patch causes MADV_WILLNEED to be ignored for hugetlbfs-backed
regions.

Subject: [CIFS] Allow raw ntlmssp code to be enabled with sec=ntlmssp

On mount, "sec=ntlmssp" can now be specified to allow
"rawntlmssp" security to be enabled during
CIFS session establishment/authentication (ntlmssp used to
require specifying krb5 which was counterintuitive).

Subject: x86, srat: do not register nodes beyond e820 map

The mem= option will truncate the memory map at a specified address so
it's not possible to register nodes with memory beyond the e820 upper
bound.

unparse_node() is only called when then node had memory associated with
it, although with the mem= option it is no longer addressable.

[ Impact: fix boot hang on certain (large) systems ]

handling in nfsd" (and 14f7dd63 "Copy XFS readdir hack into nfsd code"),
an entry may be removed between the first mutex_unlock and the second

Subject: inotify: use GFP_NOFS in kernel_event() to work around a lockdep
 false-positive

There is what we believe to be a false positive reported by lockdep.

inotify_inode_queue_event() => take inotify_mutex => kernel_event() =>
kmalloc() => SLOB => alloc_pages_node() => page reclaim => slab reclaim =>
dcache reclaim => inotify_inode_is_dead => take inotify_mutex => deadlock

The plan is to fix this via lockdep annotation, but that is proving to be
quite involved.

The patch flips the allocation over to GFP_NFS to shut the warning up, for
the 2.6.30 release.

Hopefully we will fix this for real in 2.6.31.  I'll queue a patch in -mm
to switch it back to GFP_KERNEL so we don't forget.

Subject: Eliminate thousands of warnings with gcc 3.2 build

When building with gcc 3.2 I get thousands of warnings such as

include/linux/gfp.h: In function `allocflags_to_migratetype':
include/linux/gfp.h:105: warning: null format string

due to passing a NULL format string to warn_slowpath() in

#define __WARN()		warn_slowpath(__FILE__, __LINE__, NULL)

Split this case out into a separate call.  This also shrinks the kernel
slightly:

          text    data     bss     dec     hex filename
       4802274  707668  712704 6222646  5ef336 vmlinux
          text    data     bss     dec     hex filename
       4799027  703572  712704 6215303  5ed687 vmlinux

due to removeing one argument from the commonly-called __WARN().

Subject: fiemap: fix problem with setting FIEMAP_EXTENT_LAST

Fix a problem where the generic block based fiemap stuff would not
properly set FIEMAP_EXTENT_LAST on the last extent.  I've reworked things
to keep track if we go past the EOF, and mark the last extent properly.
The problem was reported by and tested by Eric Sandeen.

Subject: oom: prevent livelock when oom_kill_allocating_task is set

When /proc/sys/vm/oom_kill_allocating_task is set for large systems that
want to avoid the lengthy tasklist scan, it's possible to livelock if
current is ineligible for oom kill.  This normally happens when it is set
to OOM_DISABLE, but is also possible if any threads are sharing the same
->mm with a different tgid.

So change __out_of_memory() to fall back to the full task-list scan if it
was unable to kill `current'.

Subject: fbdev: fix fillrect for 24bpp modes

The software fillrect routines do not work properly when the number of
pixels per machine word is not an integer.  To see that, run the following
command on a fbdev console with a 24bpp video mode, using a
non-accelerated driver such as (u)vesafb:

  reset ; echo -e '\e[41mtest\e[K'

The expected result is 'test' displayed on a line with red background.
Instead of that, 'test' has a red background, but the rest of the line
(rendered using fillrect()) contains a distored colorful pattern.

This patch fixes the problem by correctly computing rotation shifts.  It
has been tested in a 24bpp mode on 32- and 64-bit little-endian machines.

Subject: nommu: clamp zone_batchsize() to 0 under NOMMU conditions

Clamp zone_batchsize() to 0 under NOMMU conditions to stop
free_hot_cold_page() from queueing and batching frees.

The problem is that under NOMMU conditions it is really important to be
able to allocate large contiguous chunks of memory, but when munmap() or
exit_mmap() releases big stretches of memory, return of these to the buddy
allocator can be deferred, and when it does finally happen, it can be in
small chunks.

Whilst the fragmentation this incurs isn't so much of a problem under MMU
conditions as userspace VM is glued together from individual pages with
the aid of the MMU, it is a real problem if there isn't an MMU.

By clamping the page freeing queue size to 0, pages are returned to the
allocator immediately, and the buddy detector is more likely to be able to
glue them together into large chunks immediately, and fragmentation is
less likely to occur.

By disabling batching of frees, and by turning off the trimming of excess
space during boot, Coldfire can manage to boot.

Subject: nommu: make the initial mmap allocation excess behaviour Kconfig
 configurable

NOMMU mmap() has an option controlled by a sysctl variable that determines
whether the allocations made by do_mmap_private() should have the excess
space trimmed off and returned to the allocator.  Make the initial setting
of this variable a Kconfig configuration option.

The reason there can be excess space is that the allocator only allocates
in power-of-2 size chunks, but mmap()'s can be made in sizes that aren't a
power of 2.

There are two alternatives:

 (1) Keep the excess as dead space.  The dead space then remains unused for the
     lifetime of the mapping.  Mappings of shared objects such as libc, ld.so
     or busybox's text segment may retain their dead space forever.

 (2) Return the excess to the allocator.  This means that the dead space is
     limited to less than a page per mapping, but it means that for a transient
     process, there's more chance of fragmentation as the excess space may be
     reused fairly quickly.

During the boot process, a lot of transient processes are created, and
this can cause a lot of fragmentation as the pagecache and various slabs
grow greatly during this time.

By turning off the trimming of excess space during boot and disabling
batching of frees, Coldfire can manage to boot.

A better way of doing things might be to have /sbin/init turn this option
off.  By that point libc, ld.so and init - which are all long-duration
processes - have all been loaded and trimmed.

Subject: initramfs: clean up messages related to initramfs unpacking

With the removal of duplicate unpack_to_rootfs() (commit
df52092f3c97788592ef72501a43fb7ac6a3cfe0) the messages displayed do not
actually correspond to what the kernel is doing.  In addition, depending
if ramdisks are supported or not, the messages are not at all the same.

So keep the messages more in sync with what is really doing the kernel,
and only display a second message in case of failure.  This also ensure
that the printk message cannot be split by other printk's.

Subject: md: fix loading of out-of-date bitmap.

When md is loading a bitmap which it knows is out of date, it fills
each page with 1s and writes it back out again.  However the
write_page call makes used of bitmap->file_pages and
bitmap->last_page_size which haven't been set correctly yet.  So this
can sometimes fail.

Move the setting of file_pages and last_page_size to before the call
to write_page.

This bug can cause the assembly on an array to fail, thus making the
data inaccessible.  Hence I think it is a suitable candidate for
-stable.

Subject: md/raid10: don't clear bitmap during recovery if array will still be
 degraded.

If we have a raid10 with multiple missing devices, and we recover just
one of these to a spare, then we risk (depending on the bitmap and
array chunk size) clearing bits of the bitmap for which recovery isn't
complete (because a device is still missing).

This can lead to a subsequent "re-add" being recovered without
any IO happening, which would result in loss of data.

This patch takes the safe approach of not clearing bitmap bits
if the array will still be degraded.

This patch is suitable for all active -stable kernels.

Subject: md: fix some (more) errors with bitmaps on devices larger than 2TB.

If a write intent bitmap covers more than 2TB, we sometimes work with
values beyond 32bit, so these need to be sector_t.  This patches
add the required casts to some unsigned longs that are being shifted
up.

This will affect any raid10 larger than 2TB, or any raid1/4/5/6 with
member devices that are larger than 2TB.

Subject: md: tidy up status_resync to handle large arrays.

Two problems in status_resync.
1/ It still used Kilobytes as the basic block unit, while most code
   now uses sectors uniformly.
2/ It doesn't allow for the possibility that max_sectors exceeds
   the range of "unsigned long".

So
 - change "max_blocks" to "max_sectors", and store sector numbers
   in there and in 'resync'
 - Make 'rt' a 'sector_t' so it can temporarily hold the number of
   remaining sectors.
 - use sector_div rather than normal division.
 - change the magic '100' used to preserve precision to '32'.
   + making it a power of 2 makes division easier
   + it doesn't need to be as large as it was chosen when we averaged
     speed over the entire run.  Now we average speed over the last 30
     seconds or so.

Subject: md: remove ability to explicit set an inactive array to 'clean'.

Being able to write 'clean' to an 'array_state' of an inactive array
to activate it in 'clean' mode is both unnecessary and inconvenient.

It is unnecessary because the same can be achieved by writing
'active'.  This activates and array, but it still remains 'clean'
until the first write.

It is inconvenient because writing 'clean' is more often used to
cause an 'active' array to revert to 'clean' mode (thus blocking
any writes until a 'write-pending' is promoted to 'active').

Allowing 'clean' to both activate an array and mark an active array as
clean can lead to races:  One program writes 'clean' to mark the
active array as clean at the same time as another program writes
'inactive' to deactivate (stop) and active array.  Depending on which
writes first, the array could be deactivated and immediately
reactivated which isn't what was desired.

So just disable the use of 'clean' to activate an array.

This avoids a race that can be triggered with mdadm-3.0 and external
metadata, so it suitable for -stable.

Subject: md: remove rd%d links immediately after stopping an array.

md maintains link in sys/mdXX/md/ to identify which device has
which role in the array. e.g.
   rd2 -> dev-sda

indicates that the device with role '2' in the array is sda.

These links are only present when the array is active.  They are
created immediately after ->run is called, and so should be removed
immediately after ->stop is called.
However they are currently removed a little bit later, and it is
possible for ->run to be called again, thus adding these links, before
they are removed.

So move the removal earlier so they are consistently only present when
the array is active.

Subject: [ARM] 5507/1: support R_ARM_MOVW_ABS_NC and MOVT_ABS relocation types

From: Bruce Ashfield <bruce.ashfield@windriver.com>

To fully support the armv7-a instruction set/optimizations, support
for the R_ARM_MOVW_ABS_NC and R_ARM_MOVT_ABS relocation types is
required.

The MOVW and MOVT are both load-immediate instructions, MOVW loads 16
bits into the bottom half of a register, and MOVT loads 16 bits into the
top half of a register.

The relocation information for these instructions has a full 32 bit
value, plus an addend which is stored in the 16 immediate bits in the
instruction itself.  The immediate bits in the instruction are not
contiguous (the register # splits it into a 4 bit and 12 bit value),
so the addend has to be extracted accordingly and added to the value.
The value is then split and put into the instruction; a MOVW uses the
bottom 16 bits of the value, and a MOVT uses the top 16 bits.

Subject: random: make get_random_int() more random

It's a really simple patch that basically just open-codes the current
"secure_ip_id()" call, but when open-coding it we now use a _static_
hashing area, so that it gets updated every time.

And to make sure somebody can't just start from the same original seed of
all-zeroes, and then do the "half_md4_transform()" over and over until
they get the same sequence as the kernel has, each iteration also mixes in
the same old "current->pid + jiffies" we used - so we should now have a
regular strong pseudo-number generator, but we also have one that doesn't
have a single seed.

Note: the "pid + jiffies" is just meant to be a tiny tiny bit of noise. It
has no real meaning. It could be anything. I just picked the previous
seed, it's just that now we keep the state in between calls and that will
feed into the next result, and that should make all the difference.

I made that hash be a per-cpu data just to avoid cache-line ping-pong:
having multiple CPU's write to the same data would be fine for randomness,
and add yet another layer of chaos to it, but since get_random_int() is
supposed to be a fast interface I did it that way instead. I considered
using "__raw_get_cpu_var()" to avoid any preemption overhead while still
getting the hash be _mostly_ ping-pong free, but in the end good taste won
out.

Subject: Input: ff-memless - fix signed to unsigned bit overflow

When userspace sets effect->u.rumble.strong_magnitude to 0x8001 or
larger, ml_combine_effects() would always return strong_magnitude
0xffff.

Problem is that 'gain' is passed in as signed integer. Multiplying
magnitude (__u16) with gain (int) causes magnitude read as signed and
results negative value (with magnitude > 0x8000). This signed integer
is then divided and value, still negative, converted to 32bit unsigned
integer. Finally checking combine overflow min(new+old, 0xffff) gives
out 0xffff.

Fix is to simply change 'gain' to unsigned int.

Subject: ACPI: power: update error message

"Transitioning device [%s] to D%d" is not correct.
We print this line when we attempted to transition
the device, and it failed.

So instead, print
"Device [%s] failed to transition to D%d\n"

This can happen under two conditions:

1. acpi_power_transition() fails when trying to handle the
   _ON/_OFF for associated power resource.

2. acpi_evaluate_object() on the explicit _PS0/_PS3
   for that actual device could fail.

this change clarifies, but doesn't fix

Subject: ACPI: suspend: don't let device _PS3 failure prevent suspend

6328a57401dc5f5cf9931738eb7268fcd8058c49
"Enable PNPACPI _PSx Support, v3"

added a call to acpi_bus_set_power(handle, ACPI_STATE_D3)
to pnpacpi_disable_resource() before the existing call
to evaluate _DIS on the device.

This caused suspend to fail on the system in
http://bugzilla.kernel.org/show_bug.cgi?id=13243
because the sanity check to verify we entered _PS3
failed on the serial port.

As a work-around, that sanity check can be disabled
system-wide with "acpi.power_nocheck=1"

Or perhaps we should just shrug off the _PS3 failure
and carry on with _DIS like we used to -- which is
what this patch does.

Subject: IB/mlx4: Don't overwrite fast registration page list when posting
 work request

The low-level mlx4 driver modified the page-list addresses for fast
register work requests post send to big-endian, and set a "present"
bit.  This caused problems later when the consumer attempted to unmap
the pages using the page-list (using the list addresses which were
assumed to be still in CPU-endian order).  Fix the mlx4 driver to
allocate two buffers and use a private buffer for the hardware-format
bus addresses.

This patch fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1571>,
an NFS/RDMA server crash.  The cause of the crash was found by Vu Pham
of Mellanox.  The fix is along the lines suggested by Steve Wise in
comment #21 in bug 1571.

Subject: x86-64: finish cleanup_highmaps()'s job wrt. _brk_end

With the introduction of the .brk section, special care must be taken
that no unused page table entries remain if _brk_end and _end are
separated by a 2M page boundary. cleanup_highmap() runs very early and
hence cannot take care of that, hence potential entries needing to be
removed past _brk_end must be cleared once the brk allocator has done
its job.

Subject: x86, kexec: fix crashdump panic with CONFIG_KEXEC_JUMP

Tim Starling reported that crashdump will panic with kernel compiled
with CONFIG_KEXEC_JUMP due to null pointer deference in
machine_kexec_32.c: machine_kexec(), when deferencing
kexec_image. Refering to:

http://bugzilla.kernel.org/show_bug.cgi?id=13265

This patch fixes the BUG via replacing global variable reference:
kexec_image in machine_kexec() with local variable reference: image,
which is more appropriate, and will not be null.

Same BUG is in machine_kexec_64.c too, so fixed too in the same way.

Subject: x86: xen, i386: reserve Xen pagetables

The Xen pagetables are no longer implicitly reserved as part of the other
i386_start_kernel reservations, so make sure we explicitly reserve them.
This prevents them from being released into the general kernel free page
pool and reused.

[ Impact: fix Xen guest crash ]

Extend erase timeout in M25P80 SPI Flash driver.

The M25P80 drivers fails erasing sectors on a M25P128 because the ready

suitable number of seconds.

Subject: ipvs: Fix IPv4 FWMARK virtual services

This fixes the use of fwmarks to denote IPv4 virtual services
which was unfortunately broken as a result of the integration
of IPv6 support into IPVS, which was included in 2.6.28.

The problem arises because fwmarks are stored in the 4th octet
of a union nf_inet_addr .all, however in the case of IPv4 only
the first octet, corresponding to .ip, is assigned and compared.

In other words, using .all = { 0, 0, 0, htonl(svc->fwmark) always
results in a value of 0 (32bits) being stored for IPv4. This means
that one fwmark can be used, as it ends up being mapped to 0, but things
break down when multiple fwmarks are used, as they all end up being mapped
to 0.

As fwmarks are 32bits a reasonable fix seems to be to just store the fwmark
in .ip, and comparing and storing .ip when fwmarks are used.

This patch makes the assumption that in calls to ip_vs_ct_in_get()
and ip_vs_sched_persist() if the proto parameter is IPPROTO_IP then
we are dealing with an fwmark. I believe this is valid as ip_vs_in()
does fairly strict filtering on the protocol and IPPROTO_IP should
not be used in these calls unless explicitly passed when making
these calls for fwmarks in ip_vs_sched_persist().

We re-named 'DYNAMIC_PRINTK_DEBUG' to 'DYNAMIC_DEBUG' in 2.6.30....
'PRINTK_DEBUG' as pointed out never existed. So, it appears to be
extraneous, and should be removed. thanks for pointing it out.

Subject: Revert driver core: fix passing platform_data

This reverts commit ce21c7bcd796fc4f45d48781b7e85f493cc55ee5:
	We will remove platform_data field from struct device until
	all platform devices pass its specific data from platfom_device
	and all platform drivers use platform specific data passed by
	platform_device->platform_data. This kind of conversion will
	need a long time, for thousands of files is affected.

	To make the conversion easily, we allow platform specific data
	passed by struct device or struct platform_device and platform
	driver may use it from struct device or struct platform_device.

As we really don't want to do this at all.

Subject: Revert driver core: move platform_data into platform_device

This reverts commit 006f4571a15fae3a0575f2a0f9e9b63b3d1012f8:

	This patch moves platform_data from struct device into
	struct platform_device, based on the two ideas:

	1. Now all platform_driver is registered by platform_driver_register,
	   which makes probe()/release()/... of platform_driver passed parameter
	   of platform_device *, so platform driver can get platform_data from
	   platform_device;

	2. Other kind of devices do not need to use platform_data, we can
	   decrease size of device if moving it to platform_device.

	Taking into consideration of thousands of files to be fixed and they
	can't be finished in one night(maybe it will take a long time), so we
	keep platform_data in device to allow two kind of cases coexist until
	all platform devices pass its platfrom data from
	platform_device->platform_data.

	All patches to do this kind of conversion are welcome.

As we don't really want to do it, it was a bad idea.

Subject: usb-serial: ftdi_sio: fix reference counting of ftdi_private

This patch (as1238) adds proper reference counting for ftdi_sio's
private data structure.  Without it, the driver will free the
structure while it is still in use if the user unplugs the serial
device before closing the device file.

The patch also replaces a slightly dangerous
cancel_delayed_work/flush_scheduled_work pair with
cancel_delayed_work_sync, which is always safer.

Hey, I have an Edimax wireless USB adapter that uses the rt2870 chipset.
lsusb shows it as follows:

Bus 001 Device 002: ID 7392:7717

When I added that ID to rt2870.h, the device came up and worked as
expected.

Subject: nilfs2: fix possible recovery failure due to block creation without
 writer

Some function calls in nilfs_prepare_segment_for_recovery() may fail
because they can create blocks on meta data files without configuring
a writable FS-instance.  Concretely, nilfs_mdt_create_block() routine
of meta data files will fail in that case.

This fixes the problem by temporarily attaching a writable FS-instace
during the function is called.

Subject: nilfs2: fix circular locking dependency of writer mutex

This fixes the following circular locking dependency problem:

 =======================================================
 [ INFO: possible circular locking dependency detected ]
 2.6.30-rc3 #5
 -------------------------------------------------------
 segctord/3895 is trying to acquire lock:
  (&nilfs->ns_writer_mutex){+.+...}, at: [<d0d02172>]
   nilfs_mdt_get_block+0x89/0x20f [nilfs2]

 but task is already holding lock:
  (&bmap->b_sem){++++..}, at: [<d0d02d99>]
   nilfs_bmap_propagate+0x14/0x2e [nilfs2]

 which lock already depends on the new lock.

The bugfix is done by replacing call sites of nilfs_get_writer() which
are never called from read-only context with direct dereferencing of
pointer to a writable FS-instance.

Subject: GFS2: Fix glock ref counting bug

Depending on the ordering of events as we go around the
glock shrinker loop, it is possible to drop the ref count
of a glock incorrectly. It doesn't happen very often. This
patch corrects the got_ref variable, fixing the problem.

Subject: reiserfs: Expand i_mutex to enclose lookup_one_len

 2.6.30-rc3 introduced some sanity checks in the VFS code to avoid NFS
 bugs by ensuring that lookup_one_len is always called under i_mutex.

 This patch expands the i_mutex locking to enclose lookup_one_len. This was
 always required, but not not enforced in the reiserfs code since it
 does locking around the xattr interactions with the xattr_sem.

 This is obvious enough, and it survived an overnight 50 thread ACL test.

Subject: reiserfs: fixup xattr_root caching

 The xattr_root caching was broken from my previous patch set. It wouldn't
 cause corruption, but could cause decreased performance due to allocating
 a larger chunk of the journal (~ 27 blocks) than it would actually use.

 This patch loads the xattr root dentry at xattr initialization and creates
 it on-demand. Since we're using the cached dentry, there's no point
 in keeping lookup_or_create_dir around, so that's removed.

Subject: reiserfs: remove privroot hiding in lookup

 With Al Viro's patch to move privroot lookup to fs mount, there's no need
 to have special code to hide the privroot in reiserfs_lookup.

 I've also cleaned up the privroot hiding in reiserfs_readdir_dentry and
 removed the last user of reiserfs_xattrs().

Subject: New helper: deactivate_locked_super()

Does equivalent of up_write(&s->s_umount); deactivate_super(s);
However, it does not does not unlock it until it's all over.
As the result, it's safe to use to dispose of new superblock on ->get_sb()
failure exits - nobody will see the sucker until it's all over.
Equivalent using up_write/deactivate_super is safe for that purpose
if superblock is either	safe to use or has NULL ->s_root when we unlock.
Normally filesystems take the required precautions, but
	a) we do have bugs in that area in some of them.
	b) up_write/deactivate_super sequence is extremely common,
so the helper makes sense anyway.

Subject: Fix races around the access to ->s_options

Put generic_show_options read access to s_options under rcu_read_lock,
split save_mount_options() into "we are setting it the first time"
(uses in foo_fill_super()) and "we are relacing and freeing the old one",
synchronize_rcu() before kfree() in the latter.

Subject: bonding: fix panic if initialization fails

If module initialisation failed (e.g. because the bonding sysfs entry
cannot be created), kernel panics:
 IP: [<ffffffff8024910a>] destroy_workqueue+0x2d/0x146
Call Trace:
 [<ffffffff808268c4>] bond_destructor+0x28/0x78
 [<ffffffff80b64471>] netdev_run_todo+0x231/0x25a
 [<ffffffff80b6dbcd>] rtnl_unlock+0x9/0xb
 [<ffffffff81567907>] bonding_init+0x83e/0x84a

Remove the calls to bond_work_cancel_all() and destroy_workqueue();
both are also called/scheduled via bond_free_all().

bond_destroy_sysfs is unecessary because the sysfs entry has
not been created in the error case.

Subject: V4L/DVB (11575): uvcvideo: fix uvc resume failed

Now urb buffers is not freed before suspend, so uvc_alloc_urb_buffers should
return packet counts allocated originally during uvc resume, instead of zero.

This version uses round down to return packet counts on Linus' suggestions,
or else may lead to buffer destructed if packet size is changed before
calling uvc_alloc_urb_buffers() in this kind of case.

Subject: V4L/DVB (11660): zoran: fix bug when enumerating format -1

If someone requests a format at fmt->index == (unsigned)-1 and the first
format in the array doesn't have the requested type then num will still be
-1 when it's compared to fmt->index and there will appear to be a match.

Restructure the loop so this can't happen.  It's simpler this way too.  The
unnecessary check for (unsigned)fmt->index < 0 found by Roel Kluin
<roel.kluin@gmail.com> is removed this way too.

Subject: V4L/DVB (11661): v4l2-ioctl: Check buffer types using g_fmt instead
 of try_fmt

For a number of different ioctls, the v4l2-ioctl code checks that the
passed buffer type is supported by the driver.  It did this by checking
that the driver defined a method for the try_fmt handler for that buffer
type.  However, try_fmt is optional and a driver might not provide it even
though it does support that type.  So use g_fmt instead, since that isn't
optional.

This should fix a problem with VBI capture with saa7146.

Subject: V4L/DVB (11662): v4l2-ioctl: Clear buffer type specific trailing
 fields/padding

Some ioctls have structs that are a different size depending on what type
of buffer is being used.  If the buffer type leaves a field unused or has
padding space at the end, this space should be zeroed out.

The problems with S_FMT and REQBUFS were original identified and patched by
Marton Nemeth <nm127@freemail.hu>.

The 2.6.30 kernel generates this warning:

uvc_driver.c:1729: warning: 'ret' may be used uninitialized in this function

I guess some new warning flag must have been turned on since this warning
didn't appear with older kernels (gcc version 4.3.1). It's also a bogus
warning, but since this code didn't comply to the coding standard anyway
I've modified it to 1) remove the warning and 2) conform to the coding
standard.

Subject: Bluetooth: Fix wrong module refcount when connection setup fails

The module refcount is increased by hci_dev_hold() call in hci_conn_add()
and decreased by hci_dev_put() call in del_conn(). In case the connection
setup fails, hci_dev_put() is never called.

Procedure to reproduce the issue:

  # hciconfig hci0 up
  # lsmod | grep btusb                   -> "used by" refcount = 1

  # hcitool cc <non-exisiting bdaddr>    -> will get timeout

  # lsmod | grep btusb                   -> "used by" refcount = 2
  # hciconfig hci0 down
  # lsmod | grep btusb                   -> "used by" refcount = 1
  # rmmod btusb                          -> ERROR: Module btusb is in use

The hci_dev_put() call got moved into del_conn() with the 2.6.25 kernel
to fix an issue with hci_dev going away before hci_conn. However that
change was wrong and introduced this problem.

When calling hci_conn_del() it has to call hci_dev_put() after freeing
the connection details. This handling should be fully symmetric. The
execution of del_conn() is done in a work queue and needs it own calls
to hci_dev_hold() and hci_dev_put() to ensure that the hci_dev stays
until the connection cleanup has been finished.

Subject: Bluetooth: Don't use hci_acl_connect_cancel() for incoming
 connections

The connection setup phase takes around 2 seconds or longer and in
that time it is possible that the need for an ACL connection is no
longer present. If that happens then, the connection attempt will
be canceled.

This only applies to outgoing connections, but currently it can also
be triggered by incoming connection. Don't call hci_acl_connect_cancel()
on incoming connection since these have to be either accepted or rejected
in this state. Once they are successfully connected they need to be
fully disconnected anyway.

Also remove the wrong hci_acl_disconn() call for SCO and eSCO links
since at this stage they can't be disconnected either, because the
connection handle is still unknown.

Subject: Bluetooth: Don't trigger disconnect timeout for security mode 3
 pairing

A remote device in security mode 3 that tries to connect will require
the pairing during the connection setup phase. The disconnect timeout
is now triggered within 10 milliseconds and causes the pairing to fail.

If a connection is not fully established and a PIN code request is
received, don't trigger the disconnect timeout. The either successful
or failing connection complete event will make sure that the timeout
is triggered at the right time.

The biggest problem with security mode 3 is that many Bluetooth 2.0
device and before use a temporary security mode 3 for dedicated
bonding.

Subject: nilfs2: ensure to clear dirty state when deleting metadata file block

This would fix the following failure during GC:

 nilfs_cpfile_delete_checkpoints: cannot delete block
 NILFS: GC failed during preparation: cannot delete checkpoints: err=-2

The problem was caused by a break in state consistency between page
cache and btree; the above block was removed from the btree but the
page buffering the block was remaining in the page cache in dirty
state.

This resolves the inconsistency by ensuring to clear dirty state of
the page buffering the deleted block.

This makes the lock granularity of nilfs->ns_segctor_sem finer than
that of the mmap semaphore for ioctl commands except
nilfs_clean_segments().

The successive patch ("nilfs2: fix lock order reversal in
nilfs_clean_segments ioctl") is required to fully resolve the problem.

Subject: nilfs2: fix lock order reversal in nilfs_clean_segments ioctl

This is a companion patch to ("nilfs2: fix possible circular locking
for get information ioctls").

This corrects lock order reversal between mm->mmap_sem and
nilfs->ns_segctor_sem in nilfs_clean_segments() which was detected by
lockdep check:

 =======================================================
 [ INFO: possible circular locking dependency detected ]
 2.6.30-rc3-nilfs-00003-g360bdc1 #7
 -------------------------------------------------------
 mmap/5294 is trying to acquire lock:
  (&nilfs->ns_segctor_sem){++++.+}, at: [<d0d0e846>] nilfs_transaction_begin+0xb6/0x10c [nilfs2]

 but task is already holding lock:
  (&mm->mmap_sem){++++++}, at: [<c043700a>] do_page_fault+0x1d8/0x30a

 which lock already depends on the new lock.

 the existing dependency chain (in reverse order) is:

 -> #1 (&mm->mmap_sem){++++++}:
        [<c01470a5>] __lock_acquire+0x1066/0x13b0
        [<c01474a9>] lock_acquire+0xba/0xdd
        [<c01836bc>] might_fault+0x68/0x88
        [<c023c61d>] copy_from_user+0x2a/0x111
        [<d0d120d0>] nilfs_ioctl_prepare_clean_segments+0x1d/0xf1 [nilfs2]
        [<d0d0e2aa>] nilfs_clean_segments+0x6d/0x1b9 [nilfs2]
        [<d0d11f68>] nilfs_ioctl+0x2ad/0x318 [nilfs2]
        [<c01a3be7>] vfs_ioctl+0x22/0x69
        [<c01a408e>] do_vfs_ioctl+0x460/0x499
        [<c01a4107>] sys_ioctl+0x40/0x5a
        [<c01031a4>] sysenter_do_call+0x12/0x38
        [<ffffffff>] 0xffffffff

 -> #0 (&nilfs->ns_segctor_sem){++++.+}:
        [<c0146e0b>] __lock_acquire+0xdcc/0x13b0
        [<c01474a9>] lock_acquire+0xba/0xdd
        [<c0433f1d>] down_read+0x2a/0x3e
        [<d0d0e846>] nilfs_transaction_begin+0xb6/0x10c [nilfs2]
        [<d0cfe0e5>] nilfs_page_mkwrite+0xe7/0x154 [nilfs2]
        [<c0183b0b>] __do_fault+0x165/0x376
        [<c01855cd>] handle_mm_fault+0x287/0x5d1
        [<c043712d>] do_page_fault+0x2fb/0x30a
        [<c0435462>] error_code+0x72/0x78
        [<ffffffff>] 0xffffffff

where nilfs_clean_segments() holds:

  nilfs->ns_segctor_sem -> copy_from_user()
                             --> page fault -> mm->mmap_sem

And, page fault path may hold:

  page fault -> mm->mmap_sem
         --> nilfs_page_mkwrite() -> nilfs->ns_segctor_sem

Even though nilfs_clean_segments() does not perform write access on
given user pages, it may cause deadlock because nilfs->ns_segctor_sem
is shared per device and mm->mmap_sem can be shared with other tasks.

To avoid this problem, this patch moves all calls of copy_from_user()
outside the nilfs->ns_segctor_sem lock in the ioctl.

AMDs VMCB does not have an explicit unusable segment descriptor field,
so we emulate it by using "not present". This has to be setup before
the fixups, because this field is used there.

Subject: intel-iommu: PAE memory corruption fix

PAGE_MASK is 0xFFFFF000 on i386 -- even with PAE.

So it's not sufficient to ensure that you use phys_addr_t or uint64_t
everywhere you handle physical addresses -- you also have to avoid using
the construct 'addr & PAGE_MASK', because that will strip the high 32
bits of the address.

This patch avoids that problem by using PHYSICAL_PAGE_MASK instead of
PAGE_MASK where appropriate. It leaves '& PAGE_MASK' in a few instances
that don't matter -- where it's being used on the virtual bus addresses
we're dishing out, which are 32-bit anyway.

Since PHYSICAL_PAGE_MASK is not present on other architectures, we have
to define it (to PAGE_MASK) if it's not already defined.

Maybe it would be better just to fix PAGE_MASK for i386/PAE?

This patch (as1240) adds the NOGET quirk for three devices from CH
Products: the Pro pedals, the Combatstick joystick, and the Flight-Sim
yoke.  Without these quirks, the devices haven't worked for many
kernel releases.  Sometimes replugging them after boot-up would get
them to work and sometimes they wouldn't work at all.

Subject: nilfs2: check size of array structured data exchanged via ioctls

Although some ioctls of nilfs2 exchange data in the form of indirectly
referenced array, some of them lack size check on the array elements.

This inserts the missing checks and rejects requests if data of ioctl
does not have a valid format.

We usually don't have to check size of structures that we associated
with ioctl commands because the size is tested implicitly for
identifying ioctl command; the checks this patch adds are for the
cases where the implicit check is not applied.

Subject: libata: fix attach error handling

New device attach path in ata_eh_revalidate_and_attach() is divided
into two separate loops because ATA requires IDENTIFY to be issued to
slave first while the user expects to see device probe messages from
the master device.  new_mask is used to track which devices are the
new ones between the first loop and the second.

This usually works well but if an error occurs during configuration
stage, ata_dev_revalidate_and_attach() returns with error code and
forgets new_mask.  On the retry run, dev->class is set and new_mask
for the device is clear, so the device just gets revalidated and thus
ends up skipping post-configuration procedure including scheduling of
SCSI_HOTPLUG for the device.  When this occurs, ATA part of probing
works fine but SCSI probing usually doesn't happen and makes the
device unreachable.

The behavior has been around for a very long time but it has been
uncovered with the recent addition of 1_5_GBPS horkage which uses
-EAGAIN return value from ata_dev_configure() to restart the probing
sequence after forcing cable speed.

This can be fixed by making sure dev->class is permanently set only
after all configurations are successfully complete.  Fix it.

Subject: pata_pdc202xx_old: fix UDMA33 handling

The original driver doesn't use 66 MHz clock for UDMA33.

[ The alternative solution would be to adjust UDMA33 timings
  for 66 MHz clock but I think that it is safer to stick with
  old & tested behavior for now. ]

Subject: airo: airo_get_encode{,ext} potential buffer overflow

Feeding the return code of get_wep_key directly to the length parameter
of memcpy is a bad idea since it could be -1...

Subject: mac80211: avoid NULL ptr deref when finding max_rates in PID and
 minstrel

"There is another problem with this piece of code. The sband will be NULL
after second iteration on single band device and cause null pointer
dereference. Everything is working with dual band card. Sorry, but i
don't know how to explain this clearly in English. I have looked on the
second patch for pid algorithm and found similar bug."

Subject: ath5k: update channel in sw state after stopping RX and TX

This fixes a non-theoretical race condition when transmitting and
receiving frames during a scan.  If the channel or operating band
changes while processing status descriptors in the tasklets, ath5k
will incorrectly use the new channel and band when reporting the
rates, even if the frame was actually sent on a previous channel.

Typically this will manifest as a beacon found on an incorrect
frequency and/or a warning in the driver while scanning:

Add device ids for 2x2 devices. Also fix antenna usage because these devices use
antennas A and B, not B and C.

Subject: dup2: Fix return value with oldfd == newfd and invalid fd

The return value of dup2 when oldfd == newfd and the fd isn't valid is
not getting properly sign extended.  We end up with 4294967287 instead
of -EBADF.

I've reproduced this on SLE11 (2.6.27.21), openSUSE Factory
(2.6.29-rc5), and Ubuntu 9.04 (2.6.28).

This patch uses a signed int for the error value so it is properly
extended.

Commit 6c5d0512a091480c9f981162227fdb1c9d70e555 introduced this
regression.

Furthermore, the dev info output "clock=0" for old device trees was

Subject: PCI MSI: Fix MSI-X with NIU cards

The NIU device refuses to allow accesses to MSI-X registers before MSI-X
is enabled.  This patch fixes the problem by moving the read of the mask
register to after MSI-X is enabled.

Subject: xtensa: Fix architecture specific Kconfig

Move a misplace endmenu marker to enable platform options and
disable PCI and automatic calibrating for the XT2K board. The
on-board PCI bridge is somewhat broken, anyway, and the
calibrating relies on some whacky usage of the serial port.

Subject: xtensa: always use correct stack pointer for stack traces

Commit '28a0ce7 xtensa: use correct stack pointer for stack traces'
changed the stack tracer from always reading the stack pointer
register to always using the saved value in the task descriptor.

The author was too dense to consider the fact that the saved stack
value is stale for a running process und thus unusable for 'current'.

What we do now is to use the stack pointer register (a1) for when the
task is unknown - we can't help it then - or when the task is
'current'.  For everything else use the saved stack pointer value
contained in the task descriptor.

Subject: xtensa: register gpio chip before use

Platform initialization sets up the LED heartbeat that is controlled
via GPIO.  Requesting the GPIO pins fails, however, as the chip is
only initialized later by a device_initcall().

Fix this up by exporting the initialization function.  Let the
platform set up the chip before it starts using it.

Subject: xtensa: Fix linker script to include .literal sections

Fix resembles implementation from Marc Gauthier and Piet Denaly:

In the Xtensa architecture, assembly generates literals which must always
precede the code (the L32R instruction that loads them only uses negative
PC-relative offsets).  For any *.text section, literals are placed in a
corresponding *.literal section.  The linker script (vmlinux.lds) must
place these in the correct order.  It must also combine them, when the
*.text section can be larger than L32R's 256 kB range.

For example, this doesn't work:  *(.literal) *(.text) because L32R
instructions at the end of .text can't reach the literals.

The linker can solve this if they are combined in parentheses, like this:
       *(.literal .text)
because it is now allowed mix literals in .text to bring them in range.

None of this is done by standard vmlinux.lds.h macros such as TEXT_TEXT
and INIT_TEXT.  To avoid replicating the logic of that header file, we
instead post-process the generated linker script to convert *(xxx.text)
to *(xxx.literal xxx.text) for the following text sections:
       .text .ref.text .*init.text .*exit.text .text.*
using a sed script.  To do this we must override the default rule for
vmlinux.lds (see scripts/Makefile.build and the top-level Makefile)
to insert this extra step.

Subject: block: fix the bio_vec array index out-of-bounds test

Current bio_vec array index out-of-bounds test within
__end_that_request_first() does not seem correct.
It checks bio->bi_idx against bio->bi_vcnt, but the subsequent code
uses idx (which is, bio->bi_idx + next_idx) as the array index into
bio_vec array. This means that the test really make sense only at
the first iteration of !(nr_bytes >=bio->bi_size) case (when next_idx
== zero). Fix this by replacing bio->bi_idx with idx.

Subject: ext4: Fix sub-block zeroing for writes into preallocated extents

We need to mark the buffer_head mapping preallocated space as new
during write_begin. Otherwise we don't zero out the page cache content
properly for a partial write. This will cause file corruption with
preallocation.

Now that we mark the buffer_head new we also need to have a valid
buffer_head blocknr so that unmap_underlying_metadata() unmaps the
correct block.

Commit 9b8de7479d0dbab1ed98b5b015d44232c9d3d08e ("FRV: Fix the section
attribute on UP DECLARE_PER_CPU()") cleaned up DECLARE/DEFINE_PER_CPU()
macros and in the process made alpha percpu.h include
include/asm-generic/percpu.h which breaks compilation due to duplicate
definitions.

Remove inclusion of generic asm helper file and define whatever necessary
in alpha header proper.

In the longer term, percpu definitions will be unified and all these
little subtlties will be removed.

Fix a bug in viafb on x86_64 builds (e.g. for VIA Nano CPU).

You cannot make the assumption that sizeof(unsigned int) ==
sizeof(unsigned long), so the parsing of the default mode (640x480) fails,
leading to a division by zero during insmod of the driver.

Subject: ioatdma: fix "ioatdma frees DMA memory with wrong function"

as reported by Alexander Beregalov <a.beregalov@gmail.com>

ioatdma 0000:00:08.0: DMA-API: device driver frees DMA memory with
wrong function [device address=0x000000007f76f800] [size=2000 bytes]
[map
ped as single] [unmapped as page]

The ioatdma driver was unmapping all regions
(either allocated as page or single) using unmap_page.
This patch lets dma driver recognize if unmap_single or unmap_page should be used.
It introduces two new dma control flags:
DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE.
They should be set to indicate dma driver to do dma-unmapping as single
(first one for the source, tha latter for the destination).
If respective flag is not set, the driver assumes dma-unmapping as page.

Normally the block size (by default 128K) will be larger than the

Subject: Remove implementation of readpage from the hugetlbfs_aops

The core VM assumes the page size used by the address_space in
inode->i_mapping is PAGE_SIZE but hugetlbfs breaks this assumption by
inserting pages into the page cache at offsets the core VM considers
unexpected.

This would not be a problem except that hugetlbfs also provide a
->readpage implementation.  As it exists, the core VM can assume the
base page size is being used, allocate pages on behalf of the
filesystem, insert them into the page cache and call ->readpage to
populate them.  These pages are the wrong size and at the wrong offset
for hugetlbfs causing confusion.

This patch deletes the ->readpage implementation for hugetlbfs on the
grounds the core VM should not be allocating and populating pages on
behalf of hugetlbfs.  There should be no existing users of the
->readpage implementation so it should not cause a regression.

Now that the previous commit removed the "readpage" actor for hugetlb

longer any reason to treat hugetlbfs mappings specially.

Subject: MIPS: SMTC: Fix xxx_clockevent_init() naming conflict for SMTC

Commit 779e7d41ad004946603da139da99ba775f74cb1c created a name collision
in SMTC builds.  The attached patch corrects this in a a
not-too-terribly-ugly manner.  Note that the SMTC case has to come
first, because CEVT_R4K will also be true.

I have taken Wu Zhangjin's and Philippe Vachon's version as references,
did a little modification and tested on 16K page size kernel. It works
well.

Unfornately although it already has defined cpu_has_dc_aliases as 1, 4k
page size still not working.  More work needed here.

The LTP timerfd01 test is failing (blocking forever) on the 32-bit ABIs. We
need to use the compat_* wrappers for these system calls.

The compat.h does not need seccomp.h since TIF_32BIT was moved to
thread_info.h

This fixes a build error of 64-bit kernel without CONFIG_SECCOMP.

Subject: MIPS: TXx9: Fix possible overflow in clock calculations

Addition of -fwrapv option in 2.6.29 discloses possible overflow with
signed arithmetics.  For example, result of "a * 6 / 12" (int a =
400000000) is 200000000 without -fwrapv but -157913941 with -fwrapv.

Change some variable to unsigned to avoid such overflows.

There was already a define for NMI_OFFSET in asm/sn/addr.h, which now

Subject: MIPS: MSP71xx: Resolve multiple definition of plat_timer_setup

There have been a number of compile problems with the msp71xx configuration
ever since it was included in the linux-mips.org repository.  This patch
resolves the "multiple definition of plat_timer_setup" problem, and creates
the required get_c0_compare_int function.

This patch has been compile-tested against the current HEAD.

the root filesystem to the end of the kernel image.  The preferred and
portable solution is to use an initramfs instead.

introduces the variable _page_cachable_default, which defaults to zero and.
is used to create the prototype PTE for __kmap_atomic in
arch/mips/mm/init.c:kmap_init before initialization in
arch/mips/mm/c-r4k.c:coherency_setup, so the default value of 0 will be
used as the CCA of kmap atomic pages which on many processors is not a
defined CCA value and may result in writes to kmap_atomic pages getting
corrupted.  Debugged by Jon Fraser (jfraser@broadcom.com).

Subject: MIPS: Use force_sig when handling address errors.

When init is started it is SIGNAL_UNKILLABLE.  If it were to get an
address error, we would try to send it SIGBUS, but it would be ignored
and the faulting instruction restarted.  This results in an endless
loop.

We need to use force_sig() instead so it will actually die and give us
some useful information.

Subject: eeepc-laptop: fix wlan rfkill state change during init

When an rfkill device is registered, the rfkill core will change its
state to the system default. So we need to prepare for state changes
*before* we register it. That means installing the eeepc-specific ACPI
callback which handles the hotplug of the wireless network adaptor.

This problem doesn't occur during normal operation.  You have to

1) Boot with wireless enabled. eeepc-laptop should load automatically.
2) modprobe -r eeepc-laptop
3) modprobe eeepc-laptop

On boot, the default rfkill state will be set to enabled.
With the current core code, step 2) will disable the wireless.
Therefore in step 3), the wireless will change state during registration,
from disabled to enabled.  But without this fix, the PCI device for the
wireless adaptor will not appear.

Subject: eeepc-laptop: report brightness control events via the input layer

This maps the brightness control events to one of two keys, either
KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP, as needed.

Some mapping has to be done due to the fact that the BIOS reports them as
<base value> + <current brightness index>; the selection is done according to
the sign of the change in brightness (if this is 0, no keypress is reported).

Subject: eeepc-laptop: Work around rfkill firmware bug

1) Buggy firmware can change the RFKILL state by itself. This is easily
   detected.  The RFKILL API states that in such cases, we should call
   rfkill_force_state() to notify the core.

   I have reported the bug to Asus. I believe this is the right thing
   to do for robustness, even if this particular firmware bug is fixed.

2) The same bug causes the wireless toggle key to be reported as 0x11
   instead of 0x10.  0x11 is otherwise unused, so it should be safe to
   add this as a new keycode.

The bug is triggered by removing the laptop battery while hibernated.

On resume, the wireless toggle key causes the firmware to toggle the
wireless state itself.  (Also, the key is reported as 0x11 when the
current wireless state is OFF).

This is very poor behaviour because the OS can't predict whether the
firmware is controlling the RFKILL state.

Without this workaround, the bug means users have to press the wireless
toggle key twice to enable, due to the OS/firmware conflict.  (Assuming
rfkill-input or equivalent is being used).  The workaround avoids this.

I believe that acpid scripts which toggle the value of the sysfs state file
when the toggle key is pressed will be rendered ineffective by the bug,
regardless of this workaround.  If they simply toggle the state, when the
firmware has already toggled it, then you will never see a state change.

Tested on "EEEPC 4G" only.

Date: Mon, 27 Apr 2009 09:23:40 +0200
Subject: eeepc-laptop: support for super hybrid engine (SHE)

The older eeepc-acpi driver allowed to control the SHE performance
preset through a ACPI function for just this purpose. SHE underclocks
and undervolts the FSB and undervolts the CPU (at preset 2,
"powersave"), or slightly overclocks the CPU (at preset 0,
"performance"). Preset 1 is the default setting with default clocks and
voltage.

The new eeepc-laptop driver doesn't support it anymore.
The attached patch adds support for it to eeepc-laptop. It's very
straight-forward and almost trivial.

Subject: Btrfs: init inode ordered_data_close flag properly

This flag is used to decide when we need to send a given file through
the ordered code to make sure it is fully written before a transaction
commits.  It was not being properly set to zero when the inode was
being setup.

Subject: Btrfs: Don't loop forever on metadata IO failures

When a btrfs metadata read fails, the first thing we try to do is find
a good copy on another mirror of the block.  If this fails, read_tree_block()
ends up returning a buffer that isn't up to date.

The btrfs btree reading code was reworked to drop locks and repeat
the search when IO was done, but the changes didn't add a check for failed
reads.  The end result was looping forever on buffers that were never
going to become up to date.

Subject: ext4: Clear the unwritten buffer_head flag after the extent is
 initialized

The BH_Unwritten flag indicates that the buffer is allocated on disk
but has not been written; that is, the disk was part of a persistent
preallocation area.  That flag should only be set when a get_blocks()
function is looking up a inode's logical to physical block mapping.

When ext4_get_blocks_wrap() is called with create=1, the uninitialized
extent is converted into an initialized one, so the BH_Unwritten flag
is no longer appropriate.  Hence, we need to make sure the
BH_Unwritten is not left set, since the combination of BH_Mapped and
BH_Unwritten is not allowed; among other things, it will result ext4's
get_block() to be called over and over again during the write_begin
phase of write(2).

Subject: drm/i915: sanity check IER at wait_request time

We might sleep here anyway so I hope an extra uncached read is ok to
add.

In #20896 we found that vbetool clobbers the IER.  In KMS mode this is
particularly bad since we don't set the interrupt regs late (in
EnterVT), so we'd fail to get *any* interrupts at all after X started
(since some distros have scripts that call vbetool at X startup
apparently).

So this patch checks IER at wait_request time, and re-enables
interrupts if it's been clobbered.  In a proper config this check
should never be triggered.

This is really a distro issue, but having a sanity check is nice, as
long as it doesn't have a real performance hit.

Subject: drm/i915: ignore LVDS on intel graphics systems that lie about having
 it

There are a number of small form factor desktop systems with Intel mobile
graphics chips that lie and say they have an LVDS. With kernel mode-setting,
this becomes a problem, and makes native resolution boot go haywire -- for
example, my Dell Studio Hybrid, hooked to a 1920x1080 display claims to
have a 1024x768 LVDS, and the resulting graphical boot on the 1920x1080
display uses only the top left 1024x768, and auto-configured X will end
up only 1024x768 as well. With this change, graphical boot and X
both do 1920x1080 as expected.

Note that we're simply embracing and extending the early bail-out code
in place for the Mac Mini here. The xorg intel driver uses pci subsystem
device and vendor id for matching, while we're using dmi lookups here.
The MSI addition is courtesy of and tested by Bill Nottingham.

Subject: drm/i915: Set HDMI hot plug interrupt enable for only the output in
 question.

We detect HDMI output connection status by writing to HOT Plug Interrupt
Detect Enable bit in PORT_HOTPLUG_EN.  The behavior will generate a specified
interrupt, which is caught by audio driver, but during one detection driver
set all Detect Enable bits of HDMIB, HDMIC HDMID, and generate wrong
interrupt signals for current output, according to the signals audio driver
misunderstand device status. The patch intends to handle corresponding
output precisely.

Subject: drm/i915: Add new GET_PIPE_FROM_CRTC_ID ioctl.

This allows userlevel code to discover the pipe number corresponding
to a given CRTC ID. This is necessary for doing pipe-specific
operations such as waiting for vblank on a given CRTC.  Failure to use
the right pipe mapping can result in GPU hangs, or at least failure
to actually sync to vblank.

Subject: wimax/i2400m: fix device crash: fix optimization in
 _roq_queue_update_ws

When the i2400m receives data and the device indicates there has to be
reordering, we keep an sliding window implementation to sort the
packets before sending them to the network stack.

One of the "operations" that the device indicates is "queue a packet
and update the window start". When the queue is empty, this is
equivalent to "deliver the packet and update the window start".

That case was optimized in i2400m_roq_queue_update_ws() so that we
would not pointlessly queue and dequeue a packet. However, when the
optimization was active, it wasn't updating the window start. That
caused the reorder management code to get confused later on with what
seemed to be wrong reorder requests from the device.

Thus the fix implemented is to do the right thing and update the
window start in both cases, when the queue is empty (and the
optimization is done) and when not.

Subject: powerpc/iseries: Fix pci breakage due to bad dma_data initialization

Commit 4fc665b88a79a45bae8bbf3a05563c27c7337c3d "powerpc: Merge 32 and
64-bit dma code" made changes to the PCI initialisation code that added
an assignment to archdata.dma_data but only for 32 bit code.  Commit
7eef440a545c7f812ed10b49d4a10a351df9cad6 "powerpc/pci: Cosmetic cleanups
of pci-common.c" removed the conditional compilation.  Unfortunately,
the iSeries code setup the archdata.dma_data before that assignment was
done - effectively overwriting the dma_data with NULL.

Fix this up by moving the iSeries setup of dma_data into a
pci_dma_dev_setup callback.

Subject: powerpc: Fix oprofile sampling of marked events on POWER7

Description
-----------
Change ppc64 oprofile kernel driver to use the SLOT bits (MMCRA[37:39]only on
older processors where those bits are defined.

Background
----------
The performance monitor unit of the 64-bit POWER processor family has the
ability to collect accurate instruction-level samples when profiling on marked
events (i.e., "PM_MRK_<event-name>").  In processors prior to POWER6, the MMCRA
register contained "slot information" that the oprofile kernel driver used to
adjust the value latched in the SIAR at the time of a PMU interrupt.  But as of
POWER6, these slot bits in MMCRA are no longer necessary for oprofile to use,
since the SIAR itself holds the accurate sampled instruction address.  With
POWER6, these MMCRA slot bits were zero'ed out by hardware so oprofile's use of
these slot bits was, in effect, a NOP.  But with POWER7, these bits are no
longer zero'ed out; however, they serve some other purpose rather than slot
information.  Thus, using these bits on POWER7 to adjust the SIAR value results
in samples being attributed to the wrong instructions.  The attached patch
changes the oprofile kernel driver to ignore these slot bits on all newer
processors starting with POWER6.

Subject: powerpc/mpic: Fix incorrect allocation of interrupt rev-map

Before when we were setting up the irq host map for mpic we passed in
just isu_size for the size of the linear map.  However, for a number of
mpic implementations we have no isu (thus pass in 0) and will end up
with a no linear map (size = 0).  This causes us to always call
irq_find_mapping() from mpic_get_irq().

By moving the allocation of the host map to after we've determined the
number of sources we can actually benefit from having a linear map for
the non-isu users that covers all the interrupt sources.

Subject: powerpc/cell: Make ptcal more reliable

There have been a series of checkstops on QS21 related to
ptcal being set up incorrectly. On systems that only
have memory on a single node, ptcal fails when it gets
a pointer to memory on the remote node.

Moreover, agressive prefetching in memcpy and other
functions may accidentally touch the first cache line
of the page that we reserve for ptcal, which causes
an ECC checkstop.

We now allocate pages only from the specified node, moves the
ptcal area into the middle of the allocated page to avoid
potential prefetch problems and prints the address of the
ptcal area to facilitate diagnostics.

Subject: powerpc: Fix PCI ROM access

A couple of issues crept in since about 2.6.27 related to accessing PCI
device ROMs on various powerpc machines.

First, historically, we don't allocate the ROM resource in the resource
tree. I'm not entirely certain of why, I susepct they often contained
garbage on x86 but it's hard to tell. This causes the current generic
code to always call pci_assign_resource() when trying to access the said
ROM from sysfs, which will try to re-assign some new address regardless
of what the ROM BAR was already set to at boot time. This can be a
problem on hypervisor platforms like pSeries where we aren't supposed
to move PCI devices around (and in fact probably can't).

Second, our code that generates the PCI tree from the OF device-tree
(instead of doing config space probing) which we mostly use on pseries
at the moment, didn't set the (new) flag IORESOURCE_SIZEALIGN on any
resource. That means that any attempt at re-assigning such a resource
with pci_assign_resource() would fail due to resource_alignment()
returning 0.

This fixes this by doing these two things:

 - The code that calculates resource flags based on the OF device-node
is improved to set IORESOURCE_SIZEALIGN on any valid BAR, and while at
it also set IORESOURCE_READONLY for ROMs since we were lacking that too

 - We now allocate ROM resources as part of the resource tree. However
to limit the chances of nasty conflicts due to busted firmwares, we
only do it on the second pass of our two-passes allocation scheme,
so that all valid and enabled BARs get precedence.

This brings pSeries back the ability to access PCI ROMs via sysfs (and
thus initialize various video cards from X etc...).

Subject: ASoC: davinci-pcm buildfixes

This is a buildfix for the DaVinci PCM code, resyncing it with
the version in the DaVinci tree.  The notable change is using
current EDMA interfaces, which recently merged to mainline.
(The older interfaces never made it into mainline.)

NOTE:  open issue, the DMA should be to/from SRAM; see chip
errata for more info.  The artifacts are extremely easy to
hear on DM355 hardware (not yet supported in mainline), but
don't seem as audible on DM6446 hardwaare (which does have
mainline support).

Subject: ASoC: DaVinci I2S updates

This resyncs the DaVinci I2S code with the version in the DaVinci
tree.  The behavioral change uses updated clock interfaces which
recently merged to mainline.  Two other changes include adding a
comment on the ASP/McBSP/McASP confusion, and dropping pdev->id in
order to support more boards than just the DM644x EVM.

This is a build fix, resyncing the DaVinci EVM ASoC board code
with the version in the DaVinci tree.  That resync includes
support for the DM355 EVM, although that board isn't yet in
mainline.

(NOTE:  also includes a bugfix to the platform_add_resources
call, recently sent by Chaithrika U S <chaithrika@ti.com> but
not yet merged into the DaVinci tree.)

Subject: Revert "mm: add /proc controls for pdflush threads"

This reverts commit fafd688e4c0c34da0f3de909881117d374e4c7af.

Work is progressing to switch away from pdflush as the process backing
for flushing out dirty data. So it seems pointless to add more knobs
to control pdflush threads. The original author of the patch did not
have any specific use cases for adding the knobs, so we can easily
revert this before 2.6.30 to avoid having to maintain this API
forever.

Subject: sysrq, intel_fb: fix sysrq g collision

Commit 79e539453b34e35f39299a899d263b0a1f1670bd introduced a
regression where you cannot use sysrq 'g' to enter kgdb.  The solution
is to move the intel fb sysrq over to V for video instead of G for
graphics.  The SMP VOYAGER code to register for the sysrq-v is not
anywhere to be found in the mainline kernel, so the comments in the
code were cleaned up as well.

This patch also cleans up the sysrq definitions for kgdb to make it
generic for the kernel debugger, such that the sysrq 'g' can be used
in the future to enter a gdbstub or another kernel debugger.

Subject: kgdb,i386: use address that SP register points to in the exception
 frame

The treatment of the SP register is different on x86_64 and i386.
This is a regression fix that lived outside the mainline kernel from
2.6.27 to now.  The regression was a result of the original merge
consolidation of the i386 and x86_64 archs to x86.

The incorrectly reported SP on i386 prevented stack tracebacks from
working correctly in gdb.

Subject: ext4: Fix race in ext4_inode_info.i_cached_extent

If two CPU's simultaneously call ext4_ext_get_blocks() at the same
time, there is nothing protecting the i_cached_extent structure from
being used and updated at the same time.  This could potentially cause
the wrong location on disk to be read or written to, including
potentially causing the corruption of the block group descriptors
and/or inode table.

This bug has been in the ext4 code since almost the very beginning of
ext4's development.  Fortunately once the data is stored in the page
cache cache, ext4_get_blocks() doesn't need to be called, so trying to
replicate this problem to the point where we could identify its root
cause was *extremely* difficult.  Many thanks to Kevin Shanahan for
working over several months to be able to reproduce this easily so we
could finally nail down the cause of the corruption.

Subject: devpts: correctly set default options

devpts_get_sb() calls memset(0) to clear mount options and calls
parse_mount_options() if user specified any mount options.

The memset(0) is bogus since the 'mode' and 'ptmxmode' options are
non-zero by default.  parse_mount_options() restores options to default
anyway and can properly deal with NULL mount options.

So in devpts_get_sb() remove memset(0) and call parse_mount_options() even
for NULL mount options.

Bug reported by Eric Paris: http://lkml.org/lkml/2009/5/7/448.

Subject: [libata] sata_sx4: fixup interrupt handling

Issuing ATA_CMD_SET_FEATURES (0xef) times out because
pdc20621_interrupt ignores command completion since
ATA_TFLAG_POLLING flag is set.

This has already been fixed for sata_promise:

commit 51b94d2a5a90d4800e74d7348bcde098a28f4fb3
Author: Tejun Heo <htejun@gmail.com>
Date:   Fri Jun 8 13:46:55 2007 -0700

    sata_promise: use TF interface for polling NODATA commands

Also, this patch includes Mikael's original patches:

The bit 11 of command description is reserved bit in Freescale

Subject: libata: Report disk alignment and physical block size

For disks with 4KB sectors, report the correct block size and alignment
when filling out the READ CAPACITY(16) response.

This patch is based upon code from Matthew Wilcox' 4KB ATA tree.  I
fixed the bug I reported a while back caused by ATA and SCSI using
different approaches to describing the alignment.

Subject: libata: Media rotation rate and form factor heuristics

This patch provides new heuristics for parsing both the form factor and
media rotation rate ATA IDENFITY words.

The reported ATA version must be 7 or greater and the device must return
values defined as valid in the standard.  Only then are the
characteristics reported to SCSI via the VPD B1 page.

This seems like a reasonable compromise to me considering that we have
been shipping several kernel releases that key off the rotation rate bit
without any version checking whatsoever.  With no complaints so far.

Subject: ACPI: resume: re-enable SCI-enable workaround

The BIOS bug workaround mistakenly got disabled
when we followed the ACPI specification more closely
by ignoring OS updates to that bit.

(The BIOS is supposed to update SCI_EN, not the OS)

Subject: ACPI: suspend: restore BM_RLD on resume

In 2.6.29,
31878dd86b7df9a147f5e6cc6e07092b4308782b
"ACPI: remove BM_RLD access from idle entry path"
moved BM_RLD initialization to init-time from run time.

But we discovered that some BIOS do not restore BM_RLD
after suspend, causing device errors on C3 and C4
after resume.  So now the kernel restores BM_RLD.

A previous 2.6.30 patch, a71e4917dc0ebbcb5a0ecb7ca3486643c1c9a6e2,
(ACPI: idle: mark_tsc_unstable() at init-time, not run-time)
erroneously disabled the TSC on systems that did not actually
have valid deep C-states.

Move the check after the deep-C-states are validated,
via new helper, tsc_check_state(), hich replaces tsc_halts_in_c().

Subject: ACPI: Idle C-states disabled by max_cstate should not disable the TSC

Processor idle power states C2 and C3 stop the TSC on many machines.
Linux recognizes this situation and marks the TSC as unstable:

Marking TSC unstable due to TSC halts in idle

But if those same machines are booted with "processor.max_cstate=1",
then there is no need to validate C2 and C3, and no need to
disable the TSC, which can be reliably used as a clocksource.

checking for back-to-back request sense issues but drive->pc can be
NULL and even when it's not NULL, it's not safe to dereference it once
the previous command is complete because pc could have been freed or
was on stack.  Kill back-to-back REQUEST_SENSE detection.

Subject: Fix caller information for warn_slowpath_null

Ian Campbell noticed that since "Eliminate thousands of warnings with
gcc 3.2 build" (commit 57adc4d2dbf968fdbe516359688094eef4d46581) all
WARN_ON()'s currently appear to come from warn_slowpath_null(), eg:

  WARNING: at kernel/softirq.c:143 warn_slowpath_null+0x1c/0x20()

because now that warn_slowpath_null() is in the call path, the
__builtin_return_address(0) returns that, rather than the place that
caused the warning.

Fix this by splitting up the warn_slowpath_null/fmt cases differently,
using a common helper function, and getting the return address in the
right place.  This also happens to avoid the unnecessary stack usage for
the non-stdargs case, and just generally cleans things up.

Make the function name printout use %pS while at it.

Subject: netpoll: don't dereference NULL dev from np

It looks like the dev in netpoll_poll can be NULL - at lease it's
checked at the function beginning. Thus the dev->netde_ops dereference
looks dangerous.

Subject: ipconfig: handle case of delayed DHCP server

If a DHCP server is delayed, it's possible for the client to receive the 
DHCPOFFER after it has already sent out a new DHCPDISCOVER message from 
a second interface.  The client then sends out a DHCPREQUEST from the 
second interface, but the server doesn't recognize the device and 
rejects the request.

This patch simply tracks the current device being configured and throws 
away the OFFER if it is not intended for the current device.  A more 
sophisticated approach would be to put the OFFER information into the 
struct ic_device rather than storing it globally.

Subject: bridge: relay bridge multicast pkgs if !STP

Currently the bridge catches all STP packets; even if STP is turned
off.  This prevents other systems (which do have STP turned on)
from being able to detect loops in the network.

With this patch, if STP is off, then any packet sent to the STP
multicast group address is forwarded to all ports.

Based on earlier patch by Joakim Tjernlund with changes
to go through forwarding (not local chain), and optimization
that only last octet needs to be checked.

Subject: bridge: fix initial packet flood if !STP

If bridge is configured with no STP and forwarding delay of 0 (which
is typical for virtualization) then when link starts it will flood all
packets for the first 20 seconds.

This bug was introduced by a combination of earlier changes:
  * forwarding database uses hold time of zero to indicate
    user wants to always flood packets
  * optimzation of the case of forwarding delay of 0 avoids the initial
    timer tick

The fix is to just skip all the topology change detection code if
kernel STP is not being used.

Subject: bonding: fix link down handling in 802.3ad mode

One of the purposes of bonding is to allow for redundant links, and failover
correctly if the cable is pulled. If all the members of a bonded device have
no carrier present, the bonded device itself needs to report no carrier present
to user space so management tools (like routing daemons) can respond.

Bonding in 802.3ad mode does not work correctly for this because it incorrectly
chooses a link that is down as a possible aggregator.

Subject: mv643xx_eth: fix PPC DMA breakage

After 2.6.29, PPC no more admits passing NULL to the dev parameter of
the DMA API. The result is a BUG followed by solid lock-up when the 
mv643xx_eth driver brings an interface up. The following patch makes 
the driver work on my Pegasos again; it is mostly a search and replace 
of NULL by mp->dev->dev.parent in dma allocation/freeing/mapping/unmapping
functions.

Commit 518a09ef11 (tcp: Fix recvmsg MSG_PEEK influence of
blocking behavior) lets the loop run longer than the race check
did previously expect, so we need to be more careful with this
check and consider the work we have been doing.

I tried my best to deal with urg hole madness too which happens
here:
	if (!sock_flag(sk, SOCK_URGINLINE)) {
		++*seq;
		...
by using additional offset by one but I certainly have very
little interest in testing that part.

Subject: sch_teql: should not dereference skb after ndo_start_xmit()

It is illegal to dereference a skb after a successful ndo_start_xmit()
call. We must store skb length in a local variable instead.

Bug was introduced in 2.6.27 by commit 0abf77e55a2459aa9905be4b226e4729d5b4f0cb
(net_sched: Add accessor function for packet length for qdiscs)

Subject: pkt_sched: gen_estimator: use 64 bit intermediate counters for bps

gen_estimator can overflow bps (bytes per second) with Gb links, while
it was designed with a u32 API, with a theorical limit of 34360Mbit
(2^32 bytes)

Using 64 bit intermediate avbps/brate counters can allow us to reach
this theorical limit.
