Merge tag 'mm-nonmm-stable-2026-04-15-04-20' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

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

Fix and a cleanup for the fchmodat2() syscall selftest

/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!)

powerpc/net: Inline checksum wrappers and convert to scoped user access

Commit 861574d51bbd ("powerpc/uaccess: Implement masked user access")
provides optimised user access by avoiding the cost of access_ok().

Convert csum_and_copy_to_user() and csum_and_copy_from_user() to
scoped user access to benefit from masked user access.

csum_and_copy_to_user() and csum_and_copy_from_user() are only
called respectively by csum_and_copy_to_iter() and
csum_and_copy_from_iter_full() and they are only called twice.

Those functions used to be large but they were first reduced by
commit c693cc4676a0 ("saner calling conventions for
csum_and_copy_..._user()") then commit 70d65cd555c5 ("ppc: propagate
the calling conventions change down to csum_partial_copy_generic()").
With the additional size reduction provided by conversion to scoped
user access they are not worth being kept out of line.
