The power management of some devices is handled through device types
and device classes rather than through bus types. Since these
devices may also benefit from using the run-time power management
core, extend it so that the device type and device class run-time PM
callbacks can be taken into consideration by it if the bus type
callback is not defined.
Update the run-time PM core documentation to reflect this change.

This patch (as1317) fixes a bug in the PM core. When a device is
resumed following a system sleep, the core decrements the device's
runtime PM usage counter but doesn't issue an idle notification if the
counter reaches 0. This could prevent an otherwise unused device from
being runtime-suspended again after the system sleep.
The fix is to call pm_runtime_put_sync() instead of
pm_runtime_put_noidle().

Commit f2511774863487e61b56a97da07ebf8dd61d7836
(PM: Add initcall_debug style timing for suspend/resume) introduced
basic timing instrumentation, needed for a scritps/bootgraph.pl
equivalent or humans, but it missed the fact that bus types and
device classes which haven't been switched to using struct dev_pm_ops
objects yet need special handling. As a result, the suspend/resume
timing information is only available for devices whose bus types or
device classes use struct dev_pm_ops objects, so the majority of
devices is not covered.
Fix this by adding basic suspend/resume timing instrumentation for
devices whose bus types and device classes still don't use struct
dev_pm_ops objects for power management. To reduce code duplication
move the timing code to helper functions.

Just set f_flags when shoving struct file into nameidata; don't
postpone that until __dentry_open(). do_filp_open() has correct
value; lookup_instantiate_filp() doesn't - we lose the difference
between O_RDWR and 3 by that point.
We still set .intent.open.flags, so no fs code needs to be changed.

It seems a couple places such as arch/ia64/kernel/perfmon.c and
drivers/infiniband/core/uverbs_main.c could use anon_inode_getfile()
instead of a private pseudo-fs + alloc_file(), if only there were a way
to get a read-only file. So provide this by having anon_inode_getfile()
create a read-only file if we pass O_RDONLY in flags.

No driver uses SG_SET_TRANSFORM any more in Linux, since the ide-scsi
driver was removed in 2.6.29. The compat-ioctl cleanup series moved
the handling for this around, which broke building without CONFIG_BLOCK.
Just remove the code handling it for compat mode.

When alloc_file() and init_file() were combined, the error handling of
mnt_clone_write() was taken into alloc_file() in a somewhat obfuscated
way. Since we don't use the error code for anything except warning,
we might as well warn directly without an extra variable.

Currently 83xx PMC driver clears deep_sleeping variable very early,
before devices are resumed. This makes fsl_deep_sleep() unusable in
drivers' resume() callback.
Sure, drivers can store fsl_deep_sleep() value on suspend and use
the stored value on resume. But a better solution is to postpone
clearing the deep_sleeping variable, i.e. move it into finish()
callback.

It appears that we wrongly calculate dev_base for type1 config cycles.
The thing is: we shouldn't subtract hose->first_busno because PCI core
sets PCI primary, secondary and subordinate bus numbers, and PCIe
controller actually takes the registers into account. So we should use
just bus->number.
Also, according to MPC8315 reference manual, primary bus number should
always remain 0. We have PPC_INDIRECT_TYPE_SURPRESS_PRIMARY_BUS quirk
in indirect_pci.c, but since 83xx is somewhat special, it doesn't use
indirect_pci.c routines, so we have to implement the quirk specifically
for 83xx PCIe controllers.

The retry logic in ug_putc() is broken.
If the TX fifo is not ready and the counter runs out it will have a
value of -1 and no transfer should be attempted. Also, a counter
with a value of 0 means that the TX fifo got ready in the last try
and the transfer should be attempted.

Since commit 57b150cce8e004ddd36330490a68bfb59b7271e9, desc->affinity
of an irq is changed after calling desc->chip->set_affinity.
Therefore we need to fix the irq_choose_cpu() not to depend on the
desc->affinity for new mask.

Commit d28513bc7f675d28b479db666d572e078ecf182d ("Fix bug in pagetable
cache cleanup with CONFIG_PPC_SUBPAGE_PROT"), itself a fix for
breakage caused by an earlier clean up patch of mine, contains a
stupid bug. I changed the parameters of the subpage_protection()
function, but failed to update one of the callers.
This patch fixes it, and replaces a void * with a typed pointer so
that the compiler will warn on such an error in future.

On machines using the Apple U4 bridge (AKA IBM CPC945) PCIe interface such
as the latest generation G5 machines x16 slot or the x16 slot of the
PowerStation, MSIs are currently broken (and will oops when enabling).
This fixes the oops and implements proper support for those. Instead of
using the PCIe <-> HT bridge conversion, on such slots we need to use
a bunch of magic registers in the bridge as the MSI target, encoding
the interrupt number in the low bits of the address itself

This patch fixes the handling of VSX alignment faults in little-endian
mode (the current code assumes the processor is in big-endian mode).
The patch also makes the handlers clear the top 8 bytes of the register
when handling an 8 byte VSX load.
This is based on 2.6.32.

If an online-attempt on a CPU which has been offlined using H_CEDE
with an appropriate cede latency hint fails, don't panic.
Instead print the error message and let the __cpu_up() code notify the
CPU Hotplug framework of the failure, which in turn can notify the
other subsystem through CPU_UP_CANCELED.

Set need to call __set_pte_at() and not set_pte_at() from __change_page_attr()
since the later will perform checks with CONFIG_DEBUG_VM that aren't suitable
to the way we override an existing PTE. (More specifically, it doesn't let
you write over a present PTE).

Now we have high res timers there is less of a reason for a high HZ value.
Furthermore I think there a few reasons we should reduce HZ to 100:
- Timer interrupt overhead. While this overhead is small, there are
applications that are very sensitive to jitter (eg some HPC apps).
- Issues with the timer wheel code. When coming out of NO_HZ idle we work our
way through the timer code one tick at a time. If we have been idle a long
time, this adds up - I sometimes see milliseconds of time spent in that
loop.
Long term we should fix the timer wheel algorithm, but for now if we reduce
HZ then we reduce the amount of work the timer code has to do when coming
out of idle.
