Pull sound fixes from Takashi Iwai:
 "This became fairly large, containing mostly the collection of ASoC
  fixes that slipped from the previous request, so I sent now a bit
  earlier than usual. But all changes look small and mostly
  device-specific, hence nothing to worry too much.

  Majority of changes are for x86 based platforms and their CODEC
  drivers, in order to address some issues hit by their recent tests and
  fuzzing. The rest are other ASoC device-specific fixes (imx, qcom,
  wm8974, amd, rockchip) as well as a trivial fix for a kernel WARNING

snd_info_get_line() has a sanity check of NULL buffer -- both buffer
itself being NULL and buffer-&gt;buffer being NULL.  Basically both
checks are valid and necessary, but the problem is that it's with
snd_BUG_ON() macro that triggers WARN_ON().  The latter condition
(NULL buffer-&gt;buffer) can be met arbitrarily by user since the buffer
is allocated at the first write, so it means that user can trigger
WARN_ON() at will.

This patch addresses it by simply moving buffer-&gt;buffer NULL check out
of snd_BUG_ON() so that spurious WARNING is no longer triggered.

On partial_drain completion we should be in SNDRV_PCM_STATE_RUNNING
state, so set that for partially draining streams in
snd_compr_drain_notify() and use a flag for partially draining streams

While at it, add locks for stream state change in
snd_compr_drain_notify() as well.

<content type='text'>
Patch series "mm: consolidate definitions of page table accessors", v2.

The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once.  For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.

Most of these definitions are actually identical and typically it boils
down to, e.g.

static inline unsigned long pmd_index(unsigned long address)
{
        return (address &gt;&gt; PMD_SHIFT) &amp; (PTRS_PER_PMD - 1);
}

static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
        return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}

These definitions can be shared among 90% of the arches provided
XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.

For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.

These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.

This patch (of 12):

The linux/mm.h header includes &lt;asm/pgtable.h&gt; to allow inlining of the
functions involving page table manipulations, e.g.  pte_alloc() and
pmd_alloc().  So, there is no point to explicitly include &lt;asm/pgtable.h&gt;
in the files that include &lt;linux/mm.h&gt;.

The include statements in such cases are remove with a simple loop:

	for f in $(git grep -l "include &lt;linux/mm.h&gt;") ; do
		sed -i -e '/include &lt;asm\/pgtable.h&gt;/ d' $f
	done

Patch series "mm: consolidate definitions of page table accessors", v2.

The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once.  For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.

Most of these definitions are actually identical and typically it boils
down to, e.g.

static inline unsigned long pmd_index(unsigned long address)
{
        return (address &gt;&gt; PMD_SHIFT) &amp; (PTRS_PER_PMD - 1);
}

static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
        return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}

These definitions can be shared among 90% of the arches provided
XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.

For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.

Prevent SNDRV_PCM_IOCTL_LINK linking stream to itself - the code
can't handle it. Fixed commit is not where bug was introduced, but
changes the context significantly.

Add and use snd_pcm_stream_lock_nested() in snd_pcm_link/unlink
implementation.  The code is fine, but generates a lockdep complaint:

 "It was another busy development cycle, and the majority of changes are
  found in ASoC side. Below are Some highlights.

  ASoC core:
   - Lots of core cleanups and refactorings, still on-going work by
     Morimoto-san

  ASoC drivers:
   - Continued work on cleaning up and improving the Intel SOF stuff,
     along with new platform support including SoundWire

   - Fixes to make the Marvell SSPA driver work upstream

   - Support for AMD Renoir ACP, Dialog DA7212, Freescale EASRC and
     i.MX8M, Intel Elkhard Lake, Maxim MAX98390, Nuvoton NAU8812 and
     NAU8814 and Realtek RT1016.

  USB-audio:
   - Improvement for sync and implicit feedback streams with the more
     accurate frame size calculation and full-duplex support

   - Support for RME Babyface Pro and Prioneer DJ DJM

  HD-audio:
   - Fixes for Mic mute LED on HP machines

   - Re-enable support of Intel SST driver for SKL/KBL platforms

  FireWire:
   - Lots of refactoring, add support for RME FireFace and MOTU
     UltraLite-mk3"
