      由 Linus Torvalds 提交于 
      Pull file locking updates from Jeff Layton:
 "I had thought that I was going to get away without a pull request this
  cycle.  There was a NFSv4 file locking problem that cropped up that I
  tried to fix in the NFSv4 code alone, but that fix has turned out to
  be problematic.  These patches fix this in the correct way.

  Note that this touches some NFSv4 code as well.  Ordinarily I'd wait
  for Trond to ACK this, but he's on holiday right now and the bug is
  rather nasty.  So I suggest we merge this and if he raises issues with
  it we can sort it out when he gets back"

      由 Linus Torvalds 提交于 
      Pull final init.h/module.h code relocation from Paul Gortmaker:
 "With the release of 4.2-rc2 done, we should not be seeing any new code
  added that gets upset by this small code move, and we've banked yet
  another complete week of testing with this move in place on top of
  4.2-rc1 via linux-next to ensure that remained true.

  Given that, I'd like to put it in now so that people formulating new
  work for 4.3-rc1 will be exposed to the ever so slightly stricter (but
  sensible) requirements wrt.  whether they are needing init.h vs.
  module.h macros, even if they are not using linux-next.

  The diffstat of the move is slightly asymmetrical due to needing to
  leave behind a couple #ifdef in the old location and add the same ones
  to the new location, but other than that, it is a 1:1 move, complete
  with the module_init/exit trailing semicolon that we can't fix.  That
  is, until/unless someone does a tree-wide sed fix of all the
  approximately 800 currently in tree users relying on it"

      Pull tracing fix from Steven Rostedt:
 "Fengguang Wu discovered a crash that happened to be because of the
  branch tracer (traces unlikely and likely branches) when enabled with
  certain debug options.

  What happened was that various debug options like lockdep and
  DEBUG_PREEMPT can cause parts of the branch tracer to recurse outside
  its recursion protection.  In fact, part of its recursion protection
  used these features that caused the lockup.  This cleans up the code a
  little and makes the recursion protection a bit more robust"

      drm/armada: fix overlay when partially off-screen · 73068ce3
      由 Russell King 提交于 
      Fix the start address calculation when overlay is partially off screen.
fb->bits_per_pixel is not set for YUV formats, and is always zero, which
led to the first component always starting at zero.

Use drm_format_plane_cpp() instead.

This also revealed a problem in that YUYV formats toggle the U/V data
for odd pixel start address offsets.  We try to rectify that by
toggling the U/V swap, which for the most part works, but seemingly
introduces a flicker for one scan frame of swapped U/V.

However, these changes result in an overall improvement.

      drm/armada: fix missing overlay wake-up · 070f3f6b
      由 Russell King 提交于 
      Nothing was waking up the overlay plane wait queue, so we were fully
reliant on the HZ/25 wait timing out to make progress.  Fix the lack
of wake-up.

We were also mis-handling the wait_event_timeout() return value - this
returns an unsigned integer of the remaining time, or zero on timeout
and the condition evaluated false.  Checking this for less than zero
is not sane.

      drm: Provide compat ioctl for addfb2.1 · c631d5f9
      由 Tvrtko Ursulin 提交于 
      Frame buffer modifiers extensions provided in;

  commit e3eb3250
  Author: Rob Clark <robdclark@gmail.com>
  Date:   Thu Feb 5 14:41:52 2015 +0000

      drm: add support for tiled/compressed/etc modifier in addfb2

Missed the structure packing/alignment problem where 64-bit
members were added after the odd number of 32-bit ones. This
makes the compiler produce structures of different sizes under
32- and 64-bit x86 targets and makes the ioctl need explicit
compat handling.

      IB/mlx4: Optimize do_slave_init · d9a047ae
      由 Doug Ledford 提交于 
      There is little chance our memory allocation will fail, so we can
combine initializing the work structs with allocating them instead of
looping through all of them once to allocate and again to initialize.
Then when we need to actually find out if our device is up or in the
process of going down, have all of our work structs batched up, take the
spin_lock once and only once, and do all of the batch under the one
spin_lock invocation instead of incurring all of the locked memory cycles
we would otherwise incur to take/release the spin_lock over and over
again.
