Pull non-MM updates from Andrew Morton:

- "pid: make sub-init creation retryable" (Oleg Nesterov)

Make creation of init in a new namespace more robust by clearing away
some historical cruft which is no longer needed. Also some
documentation fixups

- "selftests/fchmodat2: Error handling and general" (Mark Brown)

Fix and a cleanup for the fchmodat2() syscall selftest

- "lib: polynomial: Move to math/ and clean up" (Andy Shevchenko)

- "hung_task: Provide runtime reset interface for hung task detector"
(Aaron Tomlin)

Give administrators the ability to zero out
/proc/sys/kernel/hung_task_detect_count

- "tools/getdelays: use the static UAPI headers from
tools/include/uapi" (Thomas Weißschuh)

Teach getdelays to use the in-kernel UAPI headers rather than the
system-provided ones

- "watchdog/hardlockup: Improvements to hardlockup" (Mayank Rungta)

Several cleanups and fixups to the hardlockup detector code and its
documentation

- "lib/bch: fix undefined behavior from signed left-shifts" (Josh Law)

A couple of small/theoretical fixes in the bch code

- "ocfs2/dlm: fix two bugs in dlm_match_regions()" (Junrui Luo)

- "cleanup the RAID5 XOR library" (Christoph Hellwig)

A quite far-reaching cleanup to this code. I can't do better than to
quote Christoph:

"The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography
and not using the crypto API, with the generic implementations
sitting in include/asm-generic and the arch implementations
sitting in an asm/ header in theory. The latter doesn't work for
many cases, so architectures often build the code directly into
the core kernel, or create another module for the architecture
code.

Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric
Biggers has done for the CRC and crypto libraries later. After
that it changes to better calling conventions that allow for
smarter architecture implementations (although none is contained
here yet), and uses static_call to avoid indirection function call
overhead"

- "lib/list_sort: Clean up list_sort() scheduling workarounds"
(Kuan-Wei Chiu)

Clean up this library code by removing a hacky thing which was added
for UBIFS, which UBIFS doesn't actually need

- "Fix bugs in extract_iter_to_sg()" (Christian Ehrhardt)

Fix a few bugs in the scatterlist code, add in-kernel tests for the
now-fixed bugs and fix a leak in the test itself

- "kdump: Enable LUKS-encrypted dump target support in ARM64 and
PowerPC" (Coiby Xu)

Enable support of the LUKS-encrypted device dump target on arm64 and
powerpc

- "ocfs2: consolidate extent list validation into block read callbacks"
(Joseph Qi)

Cleanup, simplify, and make more robust ocfs2's validation of extent
list fields (Kernel test robot loves mounting corrupted fs images!)

decode_stacktrace: decode caller address

Decode the caller address instead of the return address by default. This
also introduced -R option to provide return address decoding mode.

This changes the decode_stacktrace.sh to decode the line info 1byte before
the return address which will be the call(branch) instruction address. If
the return address is a symbol address (zero offset from it), it falls
back to decoding the return address.

This improves results especially when optimizations have changed the order
of the lines around the return address, or when the return address does
not have the actual line information.

With this change;

Although it is in English, it seems to be only downloadable
from the Chinese part of that website.

one register read and there are not other functions besides
regulators in this chip.

ASoC: Intel: avs: Allow for NHLT configuration

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>
From AudioDSP perspective, only gateway-related modules e.g.: Copier:

Small set of changes providing new feature which the driver is already
utilizing on the market - for its Long-Term-Support (LTS) devices.

The goal is to cover systems which shipped with invalid Non HDAudio Link
Table (NHLT) - not just the descriptors (headers), but cases where the
hardware configuration is invalid too. The table is part of the ACPI
tree and forcing BIOS updates is not a feasible solution. With the
override, the topology file can carry the hardware configuration
instead.

From AudioDSP perspective, only gateway-related modules e.g.: Copier
care about the procedure. To ensure correct order of operations when
initializing such modules, the overrides take precedence over what's
currently there in the NHLT.

scripts/decode_stacktrace.sh: fix build ID and PC source parsing

Support for parsing PC source info in stacktraces (e.g. '(P)') was added
in commit 2bff77c665ed ("scripts/decode_stacktrace.sh: fix decoding of
lines with an additional info"). However, this logic was placed after the
build ID processing. This incorrect order fails to parse lines containing
both elements, e.g.:

drm_gem_mmap_obj+0x114/0x200 [drm 03d0564e0529947d67bb2008c3548be77279fd27] (P)

This patch fixes the problem by extracting the PC source info first and
then processing the module build ID. With this change, the line above is
now properly parsed as such:

drm_gem_mmap_obj (./include/linux/mmap_lock.h:212 ./include/linux/mm.h:811 drivers/gpu/drm/drm_gem.c:1177) drm (P)

While here, also add a brief explanation the build ID section.
