8fb2226435 bus: arm-ccn: Move event cleanup routine
The function cleaning up an initialized event
was called from the "event_del" handler, instead
of being used as the "destroy" callback. In case of
events group allocation this caused NULL pointer
dereference (as events are added and deleted
multiple times then). Fixed now.

ce00a96737 mm: memcontrol: revert use of root_mem_cgroup res_counter
Dave Hansen reports a massive scalability regression in an uncontained
page fault benchmark with more than 30 concurrent threads, which he
bisected down to 05b8430123 ("mm: memcontrol: use root_mem_cgroup
res_counter") and pin-pointed on res_counter spinlock contention.

That change relied on the per-cpu charge caches to mostly swallow the
res_counter costs, but it's apparent that the caches don't scale yet.

Revert memcg back to bypassing res_counters on the root level in order
to restore performance for uncontained workloads.

10096fb108 Export sync_filesystem() for modular ->remount_fs() use
This patch changes sync_filesystem() to be EXPORT_SYMBOL().

The reason this is needed is that starting with 3.15 kernel, due to
Theodore Ts'o's commit 02b9984d64 ("fs: push sync_filesystem() down to
the file system's remount_fs()"), all file systems that have dirty data
to be written out need to call sync_filesystem() from their
->remount_fs() method when remounting read-only.

As this is now a generically required function rather than an internal
only function it should be EXPORT_SYMBOL() so that all file systems can
call it.

it in the same way as we did in io_destroy.

40bea03959 nohz: Restore NMI safe local irq work for local nohz kick
The local nohz kick is currently used by perf which needs it to be
NMI-safe. Recent commit though (7d1311b93e)
changed its implementation to fire the local kick using the remote kick
API. It was convenient to make the code more generic but the remote kick
isn't NMI-safe.

As a result:

c7cc9ba11f ARM: dts: dra7-evm: Add vtt regulator support
DRA7 evm REV G and later boards uses a vtt regulator for DDR3
termination and this is controlled by gpio7_11. This gpio is
configured in boot loader. gpio7_11, which is only available only on
Pad A22, in previous boards, is connected only to an unused pad on
expansion connector EXP_P3 and is safe to be muxed as GPIO on all
DRA7-evm versions (without a need to spin off another dts file).

Since gpio7_11 is used to control VTT and should not be reset or kept
in idle state during boot up else VTT will be disconnected and DDR
gets corrupted. So, as part of this change, mark gpio7 as no-reset and
no-idle on init.

Both QSPI and GPMC-NAND share the same Pin (A8) from the SoC for Chip Select
functionality. So both can't be enabled simultaneously.

Disable QSPI node to prevent the pin conflict as well as
be similar to 3.12 release.

2b54057c9b ARM: OMAP2+: gpmc: Don't complain if wait pin is used without r/w monitoring
For NAND read & write wait pin monitoring must be kept disabled as the
wait pin is only used to indicate NAND device ready status and not to
extend each read/write cycle.

So don't print a warning if wait pin is specified while read/write
monitoring is not in the device tree.

Sanity check wait pin number irrespective if read/write monitoring is
set or not.

6726655dfd ACPI / cpuidle: fix deadlock between cpuidle_lock and cpu_hotplug.lock
There is a following AB-BA dependency between cpu_hotplug.lock and
cpuidle_lock:

1) cpu_hotplug.lock -> cpuidle_lock
enable_nonboot_cpus()
 _cpu_up()
  cpu_hotplug_begin()
   LOCK(cpu_hotplug.lock)
 cpu_notify()
  ...
  acpi_processor_hotplug()
   cpuidle_pause_and_lock()
    LOCK(cpuidle_lock)

2) cpuidle_lock -> cpu_hotplug.lock
acpi_os_execute_deferred() workqueue
 ...
 acpi_processor_cst_has_changed()
  cpuidle_pause_and_lock()
   LOCK(cpuidle_lock)
  get_online_cpus()
   LOCK(cpu_hotplug.lock)

Fix this by reversing the order acpi_processor_cst_has_changed() does
thigs -- let it first execute the protection against CPU hotplug by
calling get_online_cpus() and obtain the cpuidle lock only after that (and
perform the symmentric change when allowing CPUs hotplug again and
dropping cpuidle lock).

a383b68d9f ACPI / scan: not cache _SUN value in struct acpi_device_pnp
The _SUN device indentification object is not guaranteed to return
the same value every time it is executed, so we should not cache its
return value, but rather execute it every time as needed.  If it is
cached, an incorrect stale value may be used in some situations.

This issue was exposed by commit 202317a573 (ACPI / scan: Add
acpi_device objects for all device nodes in the namespace).  Fix it
by avoiding to cache the return value of _SUN.

aeaac098bd toshiba_acpi: fix and cleanup toshiba_kbd_bl_mode_store()
The current code just returns -EINVAL because mode can't be equal to
both 1 and 2.

Also this function is messy so I have cleaned it up:
1) Remove initializers like "int time = -1".  Initializing variables to
   garbage values turns off GCC's uninitialized variable warnings so it
   can lead to bugs.
2) Use kstrtoint() instead of sscanf().
3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1
   and 2.
4) Don't check for "mode == -1" because that can't happen.
5) Preserve the error code from toshiba_kbd_illum_status_set().

955837d8f5 arm64 fixes for -rc4
Another handful of arm64 fixes here:
 
   - A few fixes for real issues found by smatch (after Dan's talk at KS)
   - Revert the /proc/cpuinfo changes merged during the merge window.
     We've opened a can of worms here, so we need to find out where we
     stand before we change this interface.
   - Implement KSTK_ESP for compat tasks, otherwise 32-bit Android gets
     confused wondering where its [stack] has gone
   - Misc fixes (fpsimd context handling, crypto, ...)

 "Another handful of arm64 fixes here.  They address some issues found
  by running smatch on the arch code (ignoring the false positives) and
  also stop 32-bit Android from losing track of its stack.

  There's one additional irq migration fix in the pipeline, but it came
  in after I'd tagged and tested this set.
