      Merge tag 'sound-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound · 4459f397
      由 Linus Torvalds 提交于 
      Pull sound fixes from Takashi Iwai:
 "This update became slightly bigger than usual for rc3, but most of the
  commits are small and trivial.  A large chunk is found for HD-audio
  ca0132 codec, which is mostly a clean up of the specific code, to make
  SPDIF working properly, and also in the new ASoC Arizona driver.

  One important fix is for usb-audio Oops fix since 3.5.  We still see
  some EHCI related bandwidth problem, but usb-audio should be more
  stabilized now.

  Other than that, a Kconfig fix is spread over files, and various
  HD-audio and ASoC fixes as usual, in addition to Julia's error path
  fixes."

      task_work: add a scheduling point in task_work_run() · f341861f
      由 Eric Dumazet 提交于 
      It seems commit 4a9d4b02 ("switch fput to task_work_add") re-
introduced the problem addressed in 944be0b2 ("close_files(): add
scheduling point")

If a server process with a lot of files (say 2 million tcp sockets) is
killed, we can spend a lot of time in task_work_run() and trigger a soft
lockup.

      fbcon: fix race condition between console lock and cursor timer · ec5da7f8
      由 Dave Airlie 提交于 
      So we've had a fair few reports of fbcon handover breakage between
efi/vesafb and i915 surface recently, so I dedicated a couple of
days to finding the problem.

Essentially the last thing we saw was the conflicting framebuffer
message and that was all.

So after much tracing with direct netconsole writes (printks
under console_lock not so useful), I think I found the race.

  Thread A (driver load)    Thread B (timer thread)
    unbind_con_driver ->              |
    bind_con_driver ->                |
    vc->vc_sw->con_deinit ->          |
    fbcon_deinit ->                   |
    console_lock()                    |
        |                             |
        |                       fbcon_flashcursor timer fires
        |                       console_lock() <- blocked for A
        |
        |
  fbcon_del_cursor_timer ->
    del_timer_sync
    (BOOM)

Of course because all of this is under the console lock,
we never see anything, also since we also just unbound the active
console guess what we never see anything.

Hopefully this fixes the problem for anyone seeing vesafb->kms
driver handoff.

      Merge branch 'alpha' (alpha architecture patches) · 90785be3
      由 Linus Torvalds 提交于 
      Merge alpha architecture update from Michael Cree:
 "The Alpha Maintainer, Matt Turner, is currently unavailable, so I have
  collected up patches that have been posted to the linux-alpha mailing
  list over the last couple of months, and are forwarding them to you in
  the hope that you are prepared to accept them via me.

  The patches by Al Viro and myself I have been running against kernels
  for two months now so have had quite a bit of testing.  All except one
  patch were intended for the 3.5 kernel but because of Matt's
  unavailability never got forwarded to you."

* emailed patches from Michael Cree <mcree@orcon.net.nz>: (9 commits)
  alpha: Fix fall-out from disintegrating asm/system.h
  Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts
  alpha: fix fpu.h usage in userspace
  alpha/mm/fault.c: Port OOM changes to do_page_fault
  alpha: take kernel_execve() out of entry.S
  alpha: take a bunch of syscalls into osf_sys.c

asm/system.h however arch/alpha/oprofile/common.c requires definitions

      Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts · 67a806d9
      由 Mel Gorman 提交于 
      The following build error occurred during an alpha build:

  net/core/sock.c:274:36: error: initializer element is not constant

Dave Anglin says:
> Here is the line in sock.i:
>
> struct static_key memalloc_socks = ((struct static_key) { .enabled =
> ((atomic_t) { (0) }) });

The above line contains two compound literals.  It also uses a designated
initializer to initialize the field enabled.  A compound literal is not a
constant expression.

The location of the above statement isn't fully clear, but if a compound
literal occurs outside the body of a function, the initializer list must
consist of constant expressions.
