Pull sound fixes from Takashi Iwai:
 "A collection of small fixes over several drivers, but all are driver-
  specific and nothing looks scary.

  Slightly large changes are seen in ASoC qcom driver for the bugs that
  were revealed by the recent ASoC core change to report the invalid
  register access errors. Also ASoC fsl got a slight intensive change
  for the distortion fix.

  Others are only trivial fixes or device-specific quirks"

gcc can transform the loop in a naive implementation of memset/memcpy
etc into a call to the function itself.  This optimization is enabled by
-ftree-loop-distribute-patterns.

This has been the case for a while, but gcc-10.x enables this option at
-O2 rather than -O3 as in previous versions.

Add -ffreestanding, which implicitly disables this optimization with
gcc.  It is unclear whether clang performs such optimizations, but
hopefully it will also not do so in a freestanding environment.

Since commits

  c041b5ad ("x86, boot: Create a separate string.h file to provide standard string functions")
  fb4cac57 ("x86, boot: Move memcmp() into string.h and string.c")

the decompressor stub has been using the compiler's builtin memcpy,
memset and memcmp functions, _except_ where it would likely have the
largest impact, in the decompression code itself.

Remove the #undef's of memcpy and memset in misc.c so that the
decompressor code also uses the compiler builtins.

The rationale given in the comment doesn't really apply: just because
some functions use the out-of-line version is no reason to not use the
builtin version in the rest.

Replace the comment with an explanation of why memzero and memmove are
being #define'd.

Drop the suggestion to #undef in boot/string.h as well: the out-of-line
versions are not really optimized versions, they're generic code that's
good enough for the preboot environment. The compiler will likely
generate better code for constant-size memcpy/memset/memcmp if it is
allowed to.

Most decompressors' performance is unchanged, with the exception of LZ4
and 64-bit ZSTD.

	Before	After ARCH
LZ4	  73ms	 10ms   32
LZ4	 120ms	 10ms	64
ZSTD	  90ms	 74ms	64

Measurements on QEMU on 2.2GHz Broadwell Xeon, using defconfig kernels.

Decompressor code size has small differences, with the largest being
that 64-bit ZSTD decreases just over 2k. The largest code size increase
was on 64-bit XZ, of about 400 bytes.

By default 'sdo_limit' is initialized with a default value of '8'
as per spec. This is overridden in cases where a different value is
required. However this is getting reset when snd_hdac_bus_init_chip()
is called again, which happens during runtime PM cycle.

Avoid this reset by moving 'sdo_limit' setup to 'snd_hdac_bus_init()'
function which would be called only once.

The dependency between power wells is determined by the ordering of the
power well list: when enabling the power wells for a domain, this
happens walking the power well list forward, while disabling them
happens in the reverse direction. Accordingly a power well on the list
must follow any other power well it depends on.

Since the TC AUX power wells depend on TC-cold being blocked, move the
TC-cold off power well before all AUX power wells.

igt_mm_config() calls ilog2() on the (pseudo)random 21-bit number
s>>12.  Once in 2 million seeds, this is zero and ilog2 summons
the nasal demons.

There was an attempt to handle this case with a max(), but that's
too late; ms could already be something bizarre.

Given that the low 12 bits of s and ms are always zero, it's a lot
simpler just to divide them by 4096, then everything fits into 32
bits, and we can easily generate a random number 1 <= s <= 0x1fffff.

When unloading driver by "modprobe -r amdgpu", one NULL pointer
dereference bug occurs in ras debugfs releasing. The cause is the
duplicated debugfs_remove, as drm debugfs_root dir has been cleaned
up already by drm_minor_unregister.

Pull ia64 page table fix from Mike Rapoport:
 "Fix regression in IA-64 caused by page table allocation refactoring

  The refactoring and consolidation of <asm/pgalloc.h> caused regression
  on parisc and ia64. The fix for parisc made it into v5.9-rc1 while the
  fix ia64 got delayed a bit and here it is"

* tag 'fixes-2020-08-18' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock:
  arch/ia64: Restore arch-specific pgd_offset_k implementation

Recently we found regression when running will_it_scale/page_fault3 test
on ARM64.  Over 70% down for the multi processes cases and over 20% down
for the multi threads cases.  It turns out the regression is caused by
commit 89b15332 ("mm: drop mmap_sem before calling
balance_dirty_pages() in write fault").

The test mmaps a memory size file then write to the mapping, this would
make all memory dirty and trigger dirty pages throttle, that upstream
commit would release mmap_sem then retry the page fault.  The retried
page fault would see correct PTEs installed then just fall through to
spurious TLB flush.  The regression is caused by the excessive spurious
TLB flush.  It is fine on x86 since x86's spurious TLB flush is no-op.

We could just skip the spurious TLB flush to mitigate the regression.
