Merge tag 'mm-nonmm-stable-2026-06-21-10-22' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull non-MM updates from Andrew Morton:

- "taskstats: fix TGID dead-thread stat retention" (Yiyang Chen)

Fix a taskstats TGID aggregation bug where fields added in the TGID
query path were not preserved after thread exit, and adds a kselftest
covering the regression.

- "lib/tests: string_helpers: Slight improvements" (Andy Shevchenko)

Improve lib/tests/string_helpers_kunit.c a little

- "lib/base64: decode fixes" (Josh Law)

Address minor issues in lib/base64.c

- "selftests/filelock: Make output more kselftestish" (Mark Brown)

Make the output from the ofdlocks test a bit easier for tooling to
work with. Also ignore the generated file

- "uaccess: unify inline vs outline copy_{from,to}_user() selection"
(Yury Norov)

Simplify the usercopy code by removing the selectability of inlining
copy_{from,to}_user().

- "ocfs2: validate inline xattr header consumers" (ZhengYuan Huang)

Fix a number of possible issues in the ocfs2 xattr code

- "lib and lib/cmdline enhancements" (Dmitry Antipov)

Provide additional robustness checking in the cmdline handling code
and its in-kernel testing and selftests

- "cleanup the RAID6 P/Q library" (Christoph Hellwig)

Clean up the RAID6 P/Q library to match the recent updates to the
RAID 5 XOR library and other CRC/crypto libraries

- "ocfs2: harden inode validators against forged metadata" (Michael
Bommarito)

Add three structural checks to OCFS2 dinode validation so malformed
on-disk fields are rejected before ocfs2_populate_inode() copies them
into the in-core inode

- "lib/raid: replace __get_free_pages() call with kmalloc()" (Mike
Rapoport)

Clean up the lib/raid code by using kmalloc() in more places

lib: kunit: add tests for __ashldi3(), __ashrdi3(), and __lshrdi3()

Add KUnit tests for '__ashldi3()', '__ashrdi3()', and '__lshrdi3()' helper
functions used to implement 64-bit arithmetic shift left, arithmetic shift
right and logical shift right, respectively, on a 32-bit CPUs.
