[GIT PULL] hotfixes for 6.9-rc6

[Andrew Morton]

Linus, pleae merge this batch of hotfixes.

There is one trivial conflict in
tools/testing/selftests/kselftest_harness.h - purely a textual thing.

Thanks.

  mm/hugetlb: fix DEBUG_LOCKS_WARN_ON(1) when dissolve_free_hugetlb_folio() (2024-04-25 10:07:27 -0700)

----------------------------------------------------------------
11 hotfixes.  8 are cc:stable and the remaining 3 (nice ratio!) address
post-6.8 issues or aren't considered suitable for backporting.

All except one of these are for MM.  I see no particular theme - it's
singletons all over.
