7b8ab38e8d ASoC: Updates for v3.18
- More componentisation work from Lars-Peter, this time mainly
    cleaning up the suspend and bias level transition callbacks.
  - Real system support for the Intel drivers and a bunch of fixes and
    enhancements for the associated CODEC drivers, this is going to need
    a lot quirks over time due to the lack of any firmware description of
    the boards.
  - Jack detect support for simple card from Dylan Reid.
  - A bunch of small fixes and enhancements for the Freescale drivers.
  - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32, Everest
    Semiconductor ES8328 and Freescale cards using the ASRC in newer i.MX
    processors.

62b4d20411 init/Kconfig: Fix HAVE_FUTEX_CMPXCHG to not break up the EXPERT menu
commit 03b8c7b623 ("futex: Allow
architectures to skip futex_atomic_cmpxchg_inatomic() test") added the
HAVE_FUTEX_CMPXCHG symbol right below FUTEX.  This placed it right in
the middle of the options for the EXPERT menu.  However,
HAVE_FUTEX_CMPXCHG does not depend on EXPERT or FUTEX, so Kconfig stops
placing items in the EXPERT menu, and displays the remaining several
EXPERT items (starting with EPOLL) directly in the General Setup menu.

Since both users of HAVE_FUTEX_CMPXCHG only select it "if FUTEX", make
HAVE_FUTEX_CMPXCHG itself depend on FUTEX.  With this change, the
subsequent items display as part of the EXPERT menu again; the EMBEDDED
menu now appears as the next top-level item in the General Setup menu,
which makes General Setup much shorter and more usable.

039001972a While testing some new changes for 3.18, I kept hitting a bug every so
often in the ring buffer. At first I thought it had to do with some
 of the changes I was working on, but then testing something else I
 realized that the bug was in 3.17 itself. I ran several bisects as the
 bug was not very reproducible, and finally came up with the commit
 that I could reproduce easily within a few minutes, and without the change
 I could run the tests over an hour without issue. The change fit the
 bug and I figured out a fix. That bad commit was:
 
 Commit 651e22f270 "ring-buffer: Always reset iterator to reader page"
 
 This commit fixed a bug, but in the process created another one. It used
 the wrong value as the cached value that is used to see if things changed
 while an iterator was in use. This made it look like a change always
 happened, and could cause the iterator to go into an infinite loop.

31d9f8faf9 ASoC: tlv320aic3x: fix PLL D configuration
Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.

This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

b2d9de549c ASoC: dapm: Fix NULL pointer dereference when registering card with widgets
Commit 0bd2ac3dae ("ASoC: Remove CODEC pointer from snd_soc_dapm_context")
introduced regression to snd_soc_dapm_new_controls() when registering a card
with card->dapm_widgets set. Call chain is:

    snd_soc_register_card()
    -> snd_soc_instantiate_card()
       -> snd_soc_dapm_new_controls()
          -> snd_soc_dapm_new_control()

Null pointer dereference occurs since card->dapm context doesn't have
associated component. Fix this by setting widget codec pointer
conditionally.

2c2d831c81 [SCSI] uas: disable use of blk-mq I/O path
The uas driver uses the block layer tag for USB3 stream IDs.  With
blk-mq we can get larger tag numbers that the queue depth, which breaks
this assumption.  A fix is under way for 3.18, but sits on top of
large changes so can't easily be backported.   Set the disable_blk_mq
path so that a uas device can't easily crash the system when using
blk-mq for SCSI.

abe5f97291 mm: page_alloc: fix zone allocation fairness on UP
The zone allocation batches can easily underflow due to higher-order
allocations or spills to remote nodes.  On SMP that's fine, because
underflows are expected from concurrency and dealt with by returning 0.
But on UP, zone_page_state will just return a wrapped unsigned long,
which will get past the <= 0 check and then consider the zone eligible
until its watermarks are hit.

Commit 3a025760fc ("mm: page_alloc: spill to remote nodes before
waking kswapd") already made the counter-resetting use
atomic_long_read() to accomodate underflows from remote spills, but it
didn't go all the way with it.

Make it clear that these batches are expected to go negative regardless
of concurrency, and use atomic_long_read() everywhere.

Fixes: 81c0a2bb51 ("mm: page_alloc: fair zone allocator policy")

Oleg noticed that a cleanup by Sylvain actually uncovered a bug; by
calling perf_event_free_task() when failing sched_fork() we will not yet
have done the memset() on ->perf_event_ctxp[] and will therefore try and
'free' the inherited contexts, which are still in use by the parent
process.  This is bad..
