Patch queue for 3.16 - 2014-07-08
A few bug fixes to make 3.16 work well with KVM on PowerPC:
- Fix ppc32 module builds
- Fix Little Endian hosts
- Fix Book3S HV HPTE lookup with huge pages in guest
- Fix BookE lock leak

In commit b59d9d26b we introduced implicit byte swaps for RTAS calls.
Unfortunately we messed up and didn't swizzle return values properly.
Also the old approach wasn't "sparse" compatible - we were randomly
reading __be32 values on an LE system.
Let's just do all of the swizzling explicitly with byte swaps right
where values get used. That way we can at least catch bugs using sparse.
This patch fixes XICS RTAS emulation on little endian hosts for me.

Both kvmppc_hv_entry_trampoline and kvmppc_entry_trampoline are
assembly functions that are exported to modules and also require
a valid r2.
As such we need to use _GLOBAL_TOC so we provide a global entry

With guests supporting Multiple page size per segment (MPSS),
hpte_page_size returns the actual page size used. Add a new function to
return base page size and use that to compare against the the page size
calculated from SLB. Without this patch a hpte lookup can fail since
we are comparing wrong page size in kvmppc_hv_find_lock_hpte.

With commit b6b8a1451fc40412c57d1 that introduced
vmx_check_nested_events, checks for injectable interrupts happen
at different points in time for L1 and L2 that could potentially
cause a race. The regression occurs because KVM_REQ_EVENT is always
set when nested_run_pending is set even if there's no pending interrupt.
Consequently, there could be a small window when check_nested_events
returns without exiting to L1, but an interrupt comes through soon
after and it incorrectly, gets injected to L2 by inject_pending_event
Fix this by adding a call to check for nested events too when a check
for injectable interrupt returns true

The PSW mask check of the PTRACE_POKEUSR_AREA command is incorrect.
The PSW_MASK_USER define contains the PSW_MASK_ASC bits, the ptrace
interface accepts all combinations for the address-space-control
bits. To protect the kernel space the PSW mask check in ptrace needs
to reject the address-space-control bit combination for home space.

MSI irqchip in s390 has its own mask and unmask MSI irq
functions, zpci_enable_irq() and zpci_disable_irq().
They mask and unmask MSI irq in standard ways, no arch
special. MSI driver provides two global standard functions
mask_msi_irq() and unmask_msi_irq(). Local zpci_enable_irq()
and zpci_disable_irq() are almost the same as the standard
two. the difference is local mask/unmask functions
read the mask status before mask and unmask everytime.
Then change the value and rewrite to hardware. In standard
functions, save the mask status after mask and unmask msi
irq, and use the cached status to change the mask status.
When we mask or unmask a MSI irq, we always cache its
mask status except we know need not to cache it, like in
pci_msi_shutdown. So use the standard functions to replace
the local is safe.

There is further wreckage, but this in particular seemed easy to
trigger, so blacklist this.

When CPU topology is specified in device tree, cpu_logical_map() does
not return core ID anymore, but rather full MPIDR value. This breaks
existing calculation of PMU register offsets on Exynos SoCs.
This patch fixes the problem by adjusting the code to use only core ID
bits of the value returned by cpu_logical_map() to allow CPU topology to
be specified in device tree on Exynos SoCs.

The i.MX6 reference manual doesn't make a clear distinction
between the fixed clock divider and the enable gate for the
pcie and sata reference clocks. This lead to the lvds mux
inputs in the imx6q clk driver to be parented from the
ref clock (which is the divider) instead of the actual gate,
which in turn prevents the upstream clock to actually be
enabled when lvds clk out is active.
This fixes a hard machine hang regression in kernel 3.16 for
boards where only pcie is active but no sata, as with this
kernel version the imx6-pcie driver is no longer enabling
the upstream clock directly but only lvds clk out.

Currently, the coherency fabric support registers two bus notifiers;
one for platform, one for pci bus types, with the same notifier block.
However, this is illegal and can cause serious issues: the notifier

This commit fixes this by using different notifier blocks (with the same
notifier callback) to set the platform and pci bus types notifiers.

armada_370_xp_pmsu_idle_enter
In the inline asm part of the function armada_370_xp_pmsu_idle_enter()
the input operand was used. The intent here was to let the compiler
choose this register so it could do the optimization it
needed.
However an input operand is not supposed to be modified by the inline
asm code. This can lead to improper generated instructions.
In some case generated instruction the compiler made the choice to
reuse the same register to store the return value. But in the assembly
part this register was modified, so it can lead to return an wrong
value.
The fix is to use a clobber. Thanks to this the compiler will know
that the value of this register will be modified.

The SMP boot on Armada 38x and Armada 375 Z1 is currently broken in
big-endian configurations, and this commit fixes it for both
platforms.
For Armada 375 Z1, the problem was in the
armada_375_smp_cpu1_enable_code part of the code that gets copied to
the Crypto SRAM as a work-around for an issue of the Z1 stepping. This
piece of code was not switching the CPU core to big-endian, and not
endian-swapping the value read from the Resume Address register (the
value is stored little-endian). Due to the introduction of the
conditional 'rev r1, r1' instruction, the offset between the 'ldr r0,
[pc, #4]' instruction and the value it was looking is different
between LE and BE configurations. To solve this, we instead use one
'adr' instruction followed by one 'ldr'.
For Armada 38x, the problem was simply that the CPU core was not
switched to big endian in the secondary CPU startup function.
This change was tested in LE and BE configurations on Armada 385,
Armada 375 Z1 and Armada 375 A0.

init_espfix_ap() is currently off by one level when informing hypervisor
that allocated pages will be used for ministacks' page tables.
The most immediate effect of this on a PV guest is that if
'stack_page = __get_free_page()' returns a non-zeroed-out page the hypervisor
will refuse to use it for a page table (which it shouldn't be anyway). This will
result in warnings by both Xen and Linux.
More importantly, a subsequent write to that page (again, by a PV guest) is
likely to result in fatal page fault.

The PE/COFF headers currently describe only the initialised-data
portions of the image, and result in no space being allocated for the
uninitialised-data portions. Consequently, the EFI boot stub will end
up overwriting unexpected areas of memory, with unpredictable results.
Fix by including a .bss section in the PE/COFF headers (functionally
equivalent to the init_size field in the bzImage header).

The shared efistub code for ARM and arm64 contains a local copy of
linux_banner, allowing it to be referenced from separate executables
such as the ARM decompressor. However, this introduces a dependency on
generated header files, causing unnecessary rebuilds of the stub itself
and, in case of arm64, vmlinux which contains it.
On arm64, the copy is not actually needed since we can reference the
original symbol directly, and as it turns out, there may be better ways
to deal with this for ARM as well, so let's remove it from the shared
code. If it still needs to be reintroduced for ARM later, it should live
under arch/arm anyway and not in shared code.

Commit 143e1e28cb (sched: Rework sched_domain topology definition)
introduced a number of functions with a return value of 'const int'.
gcc doesn't know what to do with that and, if the kernel is compiled
with W=1, complains with the following warnings whenever sched.h
is included.
include/linux/sched.h:875:25: warning: type qualifiers ignored on function return type
include/linux/sched.h:882:25: warning: type qualifiers ignored on function return type
include/linux/sched.h:889:25: warning: type qualifiers ignored on function return type
include/linux/sched.h:1002:21: warning: type qualifiers ignored on function return type
Commits fb2aa855 (sched, ARM: Create a dedicated scheduler topology table)
and 607b45e9a (sched, powerpc: Create a dedicated topology table) introduce
the same warning in the arm and powerpc code.
Drop 'const' from the function declarations to fix the problem.
The fix for all three patches has to be applied together to avoid
compilation failures for the affected architectures.

Mauro reported that his AMD X2 using the powernow-k8 cpufreq driver
locked up when doing cpu hotplug.
Because we called set_cyc2ns_scale() from the time_cpufreq_notifier()
unconditionally, it gets called multiple times for each freq change,
instead of only the once, when the tsc_khz value actually changes.
Because it gets called more than once, we run out of cyc2ns data slots
and stall, waiting for a free one, but because we're half way offline,
there's no consumers to free slots.
By placing the call inside the condition that actually changes tsc_khz
we avoid superfluous calls and avoid the problem.

Currently, any NMI is falsely handled by a NMI handler of NMI watchdog
if CondChgd bit in MSR_CORE_PERF_GLOBAL_STATUS MSR is set.
For example, we use external NMI to make system panic to get crash
dump, but in this case, the external NMI is falsely handled do to the
issue.
This commit deals with the issue simply by ignoring CondChgd bit.
Here is explanation in detail.
On x86 NMI watchdog uses performance monitoring feature to
periodically signal NMI each time performance counter gets overflowed.
intel_pmu_handle_irq() is called as a NMI_LOCAL handler from a NMI
handler of NMI watchdog, perf_event_nmi_handler(). It identifies an
owner of a given NMI by looking at overflow status bits in
MSR_CORE_PERF_GLOBAL_STATUS MSR. If some of the bits are set, then it
handles the given NMI as its own NMI.
The problem is that the intel_pmu_handle_irq() doesn't distinguish
CondChgd bit from other bits. Unlike the other status bits, CondChgd
bit doesn't represent overflow status for performance counters. Thus,
CondChgd bit cannot be thought of as a mark indicating a given NMI is
NMI watchdog's.
As a result, if CondChgd bit is set, any NMI is falsely handled by the
NMI handler of NMI watchdog. Also, if type of the falsely handled NMI
is either NMI_UNKNOWN, NMI_SERR or NMI_IO_CHECK, the corresponding
action is never performed until CondChgd bit is cleared.
I noticed this behavior on systems with Ivy Bridge processors: Intel
Xeon CPU E5-2630 v2 and Intel Xeon CPU E7-8890 v2. On both systems,
CondChgd bit in MSR_CORE_PERF_GLOBAL_STATUS MSR has already been set
in the beginning at boot. Then the CondChgd bit is immediately cleared
by next wrmsr to MSR_CORE_PERF_GLOBAL_CTRL MSR and appears to remain
0.
On the other hand, on older processors such as Nehalem, Xeon E7540,
CondChgd bit is not set in the beginning at boot.
I'm not sure about exact behavior of CondChgd bit, in particular when
this bit is set. Although I read Intel System Programmer's Manual to
figure out that, the descriptions I found are:
In 18.9.1:
"The MSR_PERF_GLOBAL_STATUS MSR also provides a ¡sticky bit¢ to
indicate changes to the state of performancmonitoring hardware"
In Table 35-2 IA-32 Architectural MSRs
63 CondChg: status bits of this register has changed.
These are different from the bahviour I see on the actual system as I
explained above.
At least, I think ignoring CondChgd bit should be enough for NMI
watchdog perspective.

Pull networking fixes from David Miller:
1) Bluetooth pairing fixes from Johan Hedberg.
2) ieee80211_send_auth() doesn't allocate enough tail room for the SKB,
from Max Stepanov.
3) New iwlwifi chip IDs, from Oren Givon.
4) bnx2x driver reads wrong PCI config space MSI register, from Yijing
Wang.
5) IPV6 MLD Query validation isn't strong enough, from Hangbin Liu.

7) Fix sk_dst_set() being racey with UDP sockets, leading to strange
crashes, from Eric Dumazet.
8) Interpret the NAPI budget correctly in the new systemport driver,
from Florian Fainelli.
9) VLAN code frees percpu stats in the wrong place, leading to crashes
in the get stats handler. From Eric Dumazet.
10) TCP sockets doing a repair can crash with a divide by zero, because
we invoke tcp_push() with an MSS value of zero. Just skip that part
of the sendmsg paths in repair mode. From Christoph Paasch.
11) IRQ affinity bug fixes in mlx4 driver from Amir Vadai.
12) Don't ignore path MTU icmp messages with a zero mtu, machines out
there still spit them out, and all of our per-protocol handlers for
PMTU can cope with it just fine. From Edward Allcutt.

correct kind of cookie as the argument, from Loic Prylli.
14) Fix crashes in long multicast/broadcast reassembly, from Jon Paul
Maloy.

We have to return the boolean here if the tag presents
or not, not just ANDing the TCI with the mask which results to:

To get a full tag (and not just a VID) we should access the TCI
except the VLAN_TAG_PRESENT field (which means that 802.1q header
is present). Also ensure that the VLAN_TAG_PRESENT stay on its place

Pull ARM SoC fixes from Olof Johansson:
"This week's arm-soc fixes:
- Another set of OMAP fixes
* Clock fixes
* Restart handling
* PHY regulators
* SATA hwmod data for DRA7
+ Some trivial fixes and removal of a bit of dead code
- Exynos fixes
* A bunch of clock fixes
* Some SMP fixes
* Exynos multi-core timer: register as clocksource and fix ftrace.
+ a few other minor fixes
There's also a couple more patches, and at91 fix for USB caused by
common clock conversion, and more MAINTAINERS entries for shmobile.
We're definitely switching to only regression fixes from here on out,
we've been a little less strict than usual up until now"

git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into fixes
Merge "Samsung fixes-3 for 3.16" from Kukjin Kim:
Samsung fixes-3 for v3.16
- update the parent for Auudss clock because kernel will be hang
during late boot if the parent clock is disabled in bootloader.
- enable clk handing in power domain because while power domain
on/off, its regarding clock source will be reset and it causes
a problem so need to handle it.
- add mux clocks to be used by power domain for exynos5420-mfc
during power domain on/off and property in device tree also.
- register cpuidle only for exynos4210 and exynos5250 because a
system failure will be happened on other exynos SoCs.
