      Pull regmap fixes from Mark Brown:
 "Several bug fixes for issues that have been lurking for a while:

   - Check that devices haven't set the flag saying they only support
     register at a time operation while we're doing cache syncs,
     otherwise we fail to restore caches

   - Ensure that we don't mark all registers on devices using
     format_write() as cacheable, avoiding adding a cache of things like
     reset registers which we don't want to rewrite during cache sync

   - Make sure we create the debugfs files in the correct directory"

* tag 'regmap-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:

      Revert "leds: convert blink timer to workqueue" · 9067359f
      Jiri Kosina authored 
      This reverts commit 8b37e1be.

It's broken as it changes led_blink_set() in a way that it can now sleep
(while synchronously waiting for workqueue to be cancelled). That's a
problem, because it's possible that this function gets called from atomic
context (tpt_trig_timer() takes a readlock and thus disables preemption).

This has been brought up 3 weeks ago already [1] but no proper fix has
materialized, and I keep seeing the problem since 3.17-rc1.

      f2fs: reposition unlock_new_inode to prevent accessing invalid inode · b73e5282
      Chao Yu authored 
      As the race condition on the inode cache, following scenario can appear:
[Thread a]				[Thread b]
					->f2fs_mkdir
					  ->f2fs_add_link
					    ->__f2fs_add_link
					      ->init_inode_metadata failed here
->gc_thread_func
  ->f2fs_gc
    ->do_garbage_collect
      ->gc_data_segment
        ->f2fs_iget
          ->iget_locked
            ->wait_on_inode
					  ->unlock_new_inode
        ->move_data_page
					  ->make_bad_inode
					  ->iput

When we fail in create/symlink/mkdir/mknod/tmpfile, the new allocated inode
should be set as bad to avoid being accessed by other thread. But in above
scenario, it allows f2fs to access the invalid inode before this inode was set
as bad.
This patch fix the potential problem, and this issue was found by code review.

change log from v1:
 o Add condition judgment in gc_data_segment() suggested by Changman Lee.
 o use iget_failed to simplify code.

      Will Deacon authored 
      It turns out that vendors are relying on the format of /proc/cpuinfo,
and we've even spotted out-of-tree hacks attempting to make it look
identical to the format used by arch/arm/. That means we can't afford to
churn this interface in mainline, so revert the recent reformatting of
the file for arm64 pending discussions on the list to find out what
people actually want.

This reverts commit d7a49086.

      arm64: fix bug for reloading FPSIMD state after cpu power off · 7c68a9cc
      Leo Yan authored 
      Now arm64 defers reloading FPSIMD state, but this optimization also
introduces the bug after cpu resume back from low power mode.

The reason is after the cpu has been powered off, s/w need set the
cpu's fpsimd_last_state to NULL so that it will force to reload
FPSIMD state for the thread, otherwise there has the chance to meet
the condition for both the task's fpsimd_state.cpu field contains the
id of the current cpu, and the cpu's fpsimd_last_state per-cpu variable
points to the task's fpsimd_state, so finally kernel will skip to reload
the context during it return back to userland.

      Pull Xtensa updates from Chris Zankel:
 "Xtensa improvements for 3.17:
   - support highmem on cores with aliasing data cache.  Enable highmem
     on kc705 by default
   - simplify addition of new core variants (no need to modify Kconfig /
     Makefiles)
   - improve robustness of unaligned access handler and its interaction
     with window overflow/underflow exception handlers
   - deprecate atomic and spill registers syscalls
   - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select'
     statements
   - wire up renameat2 syscall.

  Various fixes:
   - fix address checks in dma_{alloc,free}_coherent (runtime BUG)
   - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage)
   - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss
     (runtime unrecoverable exception)
   - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace
     register clobbering)

Bisect points to commit 649671c9 ("unicore32: Use get_signal()
signal_setup_done()").

This code never even compiled.  Reverting the patch does not work, since
previously used functions no longer exist, so try to fix it up.  Compile
tested only.

      Pull ARM SoC fixes from Olof Johansson:
 "Here's the weekly batch of fixes from arm-soc.

  The delta is a largeish negative delta, due to revert of SMP support
  for Broadcom's STB SoC -- it was accidentally merged before some
  issues had been addressed, so they will make a new attempt for 3.18.
  I didn't see a need for a full revert of the whole platform due to
  this, we're keeping the rest enabled.

  The rest is mostly:

   - a handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
   - some MTD/NAND fixes for OMAP
   - minor DT fixes for shmobile
   - warning fix for UP builds on vexpress/spc

  There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
  so it can boot.  Drivers and the rest had landed for 3.17, and it's
  small and isolated so it made sense to pick up now even if it's not a
  bugfix"
