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

- "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!)

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.

Merge tag 'libcrypto-updates-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull crypto library updates from Eric Biggers:
"This is the main crypto library pull request for 6.17. The main focus
this cycle is on reorganizing the SHA-1 and SHA-2 code, providing
high-quality library APIs for SHA-1 and SHA-2 including HMAC support,
and establishing conventions for lib/crypto/ going forward:

- Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares
most of the SHA-512 code) into lib/crypto/. This includes both the
generic and architecture-optimized code. Greatly simplify how the
architecture-optimized code is integrated. Add an easy-to-use
library API for each SHA variant, including HMAC support. Finally,
reimplement the crypto_shash support on top of the library API.

- Apply the same reorganization to the SHA-256 code (and also SHA-224
which shares most of the SHA-256 code). This is a somewhat smaller
change, due to my earlier work on SHA-256. But this brings in all
the same additional improvements that I made for SHA-1 and SHA-512.

There are also some smaller changes:

- Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code
from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For
these algorithms it's just a move, not a full reorganization yet.

- Fix the MIPS chacha-core.S to build with the clang assembler.

- Fix the Poly1305 functions to work in all contexts.

- Fix a performance regression in the x86_64 Poly1305 code.

- Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.

Note that since the new organization of the SHA code is much simpler,
the diffstat of this pull request is negative, despite the addition of
new fully-documented library APIs for multiple SHA and HMAC-SHA
variants.

These APIs will allow further simplifications across the kernel as
users start using them instead of the old-school crypto API. (I've
already written a lot of such conversion patches, removing over 1000
more lines of code. But most of those will target 6.18 or later)"

Merge tag 'crc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull CRC updates from Eric Biggers:

- Reorganize the architecture-optimized CRC code

It now lives in lib/crc/$(SRCARCH)/ rather than arch/$(SRCARCH)/lib/,
and it is no longer artificially split into separate generic and arch
modules. This allows better inlining and dead code elimination

The generic CRC code is also no longer exported, simplifying the API.
(This mirrors the similar changes to SHA-1 and SHA-2 in lib/crypto/,
which can be found in the "Crypto library updates" pull request)

- Improve crc32c() performance on newer x86_64 CPUs on long messages by
enabling the VPCLMULQDQ optimized code

- Simplify the crypto_shash wrappers for crc32_le() and crc32c()

Register just one shash algorithm for each that uses the (fully
optimized) library functions, instead of unnecessarily providing
direct access to the generic CRC code

- Remove unused and obsolete drivers for hardware CRC engines

- Remove CRC-32 combination functions that are no longer used

- Add kerneldoc for crc32_le(), crc32_be(), and crc32c()

- Convert the crc32() macro to an inline function

lib/crc: powerpc: Migrate optimized CRC code into lib/crc/

Move the powerpc-optimized CRC code from arch/powerpc/lib/crc* into its
new location in lib/crc/powerpc/, and wire it up in the new way. This
new way of organizing the CRC code eliminates the need to artificially
split the code for each CRC variant into separate arch and generic
modules, enabling better inlining and dead code elimination. For more
details, see "lib/crc: Prepare for arch-optimized code in subdirs of
lib/crc/".

lib/crypto: powerpc: Move arch/powerpc/lib/crypto/ into lib/crypto/

Move the contents of arch/powerpc/lib/crypto/ into lib/crypto/powerpc/.

The new code organization makes a lot more sense for how this code
actually works and is developed. In particular, it makes it possible to
build each algorithm as a single module, with better inlining and dead
code elimination. For a more detailed explanation, see the patchset
which did this for the CRC library code:
https://lore.kernel.org/r/20250607200454.73587-1-ebiggers@kernel.org/.
Also see the patchset which did this for SHA-512:
https://lore.kernel.org/linux-crypto/20250616014019.415791-1-ebiggers@kernel.org/

This is just a preparatory commit, which does the move to get the files
into their new location but keeps them building the same way as before.
Later commits will make the actual improvements to the way the
arch-optimized code is integrated for each algorithm.
