Merge tag 'mm-nonmm-stable-2026-08-22-16-57' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull non-MM updates from Andrew Morton:

- "ocfs2/dlm: bound peer-controlled lengths in the o2dlm" (Bryam
Vargas)

Validate and bound all input lengths and count fields in the o2dlm
migration and recovery receive handlers to prevent memory corruption
and kernel panics from malformed cluster messages

- "ocfs2: validate xattr entry bounds" (Cen Zhang)

Validate OCFS2 extended attribute entry name and value bounds during
metadata reads to prevent out-of-range memory accesses during
retrieval or listing operations.

- "taskstats: fix cgroupstats invalid fd handling and add selftests"
(Yiyang Chen)

Return -EBADF when cgroupstats receives an invalid file descriptor to
prevent caller hangs and misleading success ACKs. Add a kselftest to
validate valid cgroup v1 queries and verify proper error handling
across different Netlink flag combinations.

- "misc lib/raid/ improvements v2" (Christoph Hellwig)

Improve benchmark-based algorithm selection for the XOR and RAID6
libraries, add KUnit benchmark tests, and cleanup minor
implementation details.

- "ocfs2: cluster: o2hb_region_pin() fixes" (Joseph Qi)

Fix sleeping-in-atomic, lock order inversion and error-path cleanup
bugs in o2hb_region_pin() by releasing o2hb_live_lock across sleeping
configfs_depend_item() calls and using unlocked variants from
callback context. Ensure failed pin attempts properly decrement user
counts and unpin partially initialized heartbeat regions to prevent
memory leaks and unprotected states.

- "lib/ucs2_string.c: fix out-of-bounds read in ucs2_strnlen()"
(Vincent Mailhol)

Fix an off-by-one which could cause an out-of-bounds read.

- "ocfs2: harden heartbeat teardown races" (Cen Zhang)

Fix two OCFS2 heartbeat/o2net teardown races found by KASAN.

- "taskstats: tidy up the cpumask command path" *Bradley Morgan)

make two small cleanups in kernel/taskstats.c.

- "ocfs2: validate active orphan slots during inode read" (ZhengYuan
Huang)

Validate active ordinary and append-DIO orphan slots read from OCFS2
dinodes at the metadata boundary to prevent corrupted slot indices
from causing out-of-bounds array accesses.

- "ocfs2: bound-check both readdir re-validation scans" (Zhan Xusheng)

Enforce strict boundary checks on directory entry record lengths and
offset calculations during OCFS2 directory re-scans to prevent
out-of-bounds memory reads and directory position corruption.

lib/math: add KUnit test suite for polynomial_calc()

Add a KUnit test suite for the polynomial_calc() function, which had no
in-kernel test coverage. The tests verify correct evaluation of constant,
linear, quadratic, and cubic polynomials, including negative coefficients,
negative input data, zero-coefficient terms.

The Kconfig entry uses 'select POLYNOMIAL' rather than 'depends on
POLYNOMIAL' because POLYNOMIAL is a promptless tristate that cannot
be manually enabled on UML without an explicit selector.

Merge branch 'for-6.15/amd_sfh' into for-linus

From: Mario Limonciello <mario.limonciello@amd.com>

Some platforms include a human presence detection (HPD) sensor. When
enabled and a user is detected a wake event will be emitted from the
sensor fusion hub that software can react to.

Example use cases are "wake from suspend on approach" or to "lock
when leaving".

This is currently enabled by default on supported systems, but users
can't control it. This essentially means that wake on approach is
enabled which is a really surprising behavior to users that don't
expect it.

Instead of defaulting to enabled add a sysfs knob that users can
use to enable the feature if desirable and set it to disabled by
default.

Extract a private header and convert the prime_numbers self-test to a

logic is entangled with the test parameter generation logic.
