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!)

scripts/decodecode: return 0 on success

The decodecode script always returns an exit code of 1, regardless of
whether the operation was successful or not. This is because the
"cleanup" function, which is registered to run on any script exit via
"trap cleanup EXIT", contains an unconditional "exit 1".

Remove the "exit 1" from the "cleanup" function so that it only performs
the necessary file cleanup without forcing a non-zero exit status.

Do that to ensure successful script executions now exit with code 0.
Exits due to errors are all handled by the "die()" function and will still
correctly exit with code 1.

Pull non-MM updates from Andrew Morton:
"Quite a lot of kexec work this time around. Many singleton patches in
many places. The notable patch series are:

- nilfs2 folio conversion from Matthew Wilcox in 'nilfs2: Folio
conversions for file paths'.

- Additional nilfs2 folio conversion from Ryusuke Konishi in 'nilfs2:
Folio conversions for directory paths'.

- IA64 remnant removal in Heiko Carstens's 'Remove unused code after
IA-64 removal'.

- Arnd Bergmann has enabled the -Wmissing-prototypes warning
everywhere in 'Treewide: enable -Wmissing-prototypes'. This had
some followup fixes:

- Nathan Chancellor has cleaned up the hexagon build in the series
'hexagon: Fix up instances of -Wmissing-prototypes'.

- Nathan also addressed some s390 warnings in 's390: A couple of
fixes for -Wmissing-prototypes'.

- Arnd Bergmann addresses the same warnings for MIPS in his series
'mips: address -Wmissing-prototypes warnings'.

- Baoquan He has made kexec_file operate in a top-down-fitting manner
similar to kexec_load in the series 'kexec_file: Load kernel at top
of system RAM if required'

- Baoquan He has also added the self-explanatory 'kexec_file: print
out debugging message if required'.

- Some checkstack maintenance work from Tiezhu Yang in the series
'Modify some code about checkstack'.

- Douglas Anderson has disentangled the watchdog code's logging when
multiple reports are occurring simultaneously. The series is
'watchdog: Better handling of concurrent lockups'.

- Yuntao Wang has contributed some maintenance work on the crash code
in 'crash: Some cleanups and fixes'"
