ASoC: Fixes for v3.17

Another round of again fairly unexciting fixes - several driver fixes,
an e-mail address change and a fix for error handling with DPCM.

commit 03b8c7b6 ("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.

Pull trace ring buffer iterator fix from Steven Rostedt:
 "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 651e22f2 "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"

Commit 0bd2ac3d ("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.

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.

Merge fixes from Andrew Morton:
 "5 fixes"

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  mm: page_alloc: fix zone allocation fairness on UP
  perf: fix perf bug in fork()
  MAINTAINERS: change git URL for mpc5xxx tree
  mm: memcontrol: do not iterate uninitialized memcgs
  ocfs2/dlm: should put mle when goto kill in dlm_assert_master_handler

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 3a025760 ("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.
