ASoC: Fixes for v3.15

A smattering of device specific fixes, nothing stands out here except
for the multiplatform fixes for Samsung and the device IDs being added
by Stephen Warren - there's no real code changes from those and they
give better robustness to the enumeration with DT.

Pull i2c updates from Wolfram Sang:
 "Here is the pull request from the i2c subsystem.  It got a little
  delayed because I needed to wait for a dependency to be included
  (commit b424080a: "reset: Add optional resets and stubs").  Plus,
  I had some email problems.  All done now, the highlights are:

   - drivers can now deprecate their use of i2c classes.  That shouldn't
     be used on embedded platforms anyhow and was often blindly
     copy&pasted.  This mechanism gives users time to switch away and
     ultimately boot faster once the use of classes for those drivers is
     gone for good.

   - new drivers for QUP, Cadence, efm32

   - tracepoint support for I2C and SMBus

   - bigger cleanups for the mv64xxx, nomadik, and designware drivers

  And the usual bugfixes, cleanups, feature additions.  Most stuff has
  been in linux-next for a while.  Just some hot fixes and new drivers
  were added a bit more recently."

 "Here are a few more powerpc things for you.

  So you'll find here the conversion of the two new firmware sysfs
  interfaces to the new API for self-removing files that Greg and Tejun
  introduced, so they can finally remove the old one.

  I'm also reverting the hwmon driver for powernv.  I shouldn't have
  merged it, I got a bit carried away here.  I hadn't realized it was
  never CCed to the relevant maintainer(s) and list(s), and happens to
  have some issues so I'm taking it out and it will come back via the
  proper channels.

  The rest is a bunch of LE fixes (argh, some of the new stuff was
  broken on LE, I really need to start testing LE myself !) and various
  random fixes here and there.

  Finally one bit that's not strictly a fix, which is the HVC OPAL
  change to "kick" the HVC thread when the firmware tells us there is
  new incoming data.  I don't feel like waiting for this one, it's
  simple enough, and it makes a big difference in console responsiveness

Jan Stancek reported:
 "pthread_cond_broadcast/4-1.c testcase from openposix testsuite (LTP)
  occasionally fails, because some threads fail to wake up.

  Testcase creates 5 threads, which are all waiting on same condition.
  Main thread then calls pthread_cond_broadcast() without holding mutex,
  which calls:

      futex(uaddr1, FUTEX_CMP_REQUEUE_PRIVATE, 1, 2147483647, uaddr2, ..)

  This immediately wakes up single thread A, which unlocks mutex and
  tries to wake up another thread:

      futex(uaddr2, FUTEX_WAKE_PRIVATE, 1)

  If thread A manages to call futex_wake() before any waiters are
  requeued for uaddr2, no other thread is woken up"

The ordering constraints for the hash bucket waiter counting are that
the waiter counts have to be incremented _before_ getting the spinlock
(because the spinlock acts as part of the memory barrier), but the
"requeue" operation didn't honor those rules, and nobody had even
thought about that case.

This fairly simple patch just increments the waiter count for the target
hash bucket (hb2) when requeing a futex before taking the locks.  It
then decrements them again after releasing the lock - the code that
actually moves the futex(es) between hash buckets will do the additional
required waiter count housekeeping.

This was caused by that 'sd->groups == NULL' after building groups, which
was caused by the empty 'sd->span'.

The cpu's domain contained nothing because the cpu was assigned to a wrong
node, due to the following unfortunate sequence of events:

1. The hypervisor sent a topology update to the guest OS, to notify changes
   to the cpu-node mapping. However, the update was actually redundant - i.e.,
   the "new" mapping was exactly the same as the old one.

2. Due to this, the 'updated_cpus' mask turned out to be empty after exiting
   the 'for-loop' in arch_update_cpu_topology().

3. So we ended up calling stop-machine() with an empty cpumask list, which made
   stop-machine internally elect cpumask_first(cpu_online_mask), i.e., CPU0 as
   the cpu to run the payload (the update_cpu_topology() function).

4. This causes update_cpu_topology() to be run by CPU0. And since 'updates'
   is kzalloc()'ed inside arch_update_cpu_topology(), update_cpu_topology()
   finds update->cpu as well as update->new_nid to be 0. In other words, we
   end up assigning CPU0 (and eventually its siblings) to node 0, incorrectly.

Along with the following wrong updating, it causes the sched-domain rebuild
code to break and crash the system.

Fix this by skipping the topology update in cases where we find that
the topology has not actually changed in reality (ie., spurious updates).

Currently we wrongly allocate mc_recoverable_range buffer (to hold

This results in allocating less memory to hold available recoverable range
entries from /proc/device-tree/ibm,opal/mcheck-recoverable-ranges.

This patch fixes this issue by allocating mc_recoverable_range buffer based
on number of entries of recoverable ranges instead of device property size.

Pull nfsd updates from Bruce Fields:
 "Highlights:
   - server-side nfs/rdma fixes from Jeff Layton and Tom Tucker
   - xdr fixes (a larger xdr rewrite has been posted but I decided it
     would be better to queue it up for 3.16).
   - miscellaneous fixes and cleanup from all over (thanks especially to
     Kinglong Mee)"

Merge a few more patches from Andrew Morton:
 "A few leftovers"

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  fs/ncpfs/dir.c: fix indenting in ncp_lookup()
  ncpfs/inode.c: fix mismatch printk formats and arguments
  ncpfs: remove now unused PRINTK macro
  ncpfs: convert PPRINTK to ncp_vdbg
  ncpfs: convert DPRINTK/DDPRINTK to ncp_dbg
  ncpfs: Add pr_fmt and convert printks to pr_<level>
  arch/x86/mm/kmemcheck/kmemcheck.c: use kstrtoint() instead of sscanf()
  lib/percpu_counter.c: fix bad percpu counter state during suspend
  autofs4: check dev ioctl size before allocating
  mm: vmscan: do not swap anon pages just because free+file is low

My static checker suggests adding curly braces here.  Probably that was
the intent, but actually the code works the same either way.  I've just
changed the indenting and left the code as-is.
