Merge tag 'mm-hotfixes-stable-2024-08-17-19-34' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull misc fixes from Andrew Morton: "16 hotfixes. All except one are for MM. 10 of these are cc:stable and the others pertain to post-6.10 issues. As usual with these merges, singletons and doubletons all over the place, no identifiable-by-me theme. Please see the lovingly curated changelogs to get the skinny" * tag 'mm-hotfixes-stable-2024-08-17-19-34' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: mm/migrate: fix deadlock in migrate_pages_batch() on large folios alloc_tag: mark pages reserved during CMA activation as not tagged alloc_tag: introduce clear_page_tag_ref() helper function crash: fix riscv64 crash memory reserve dead loop selftests: memfd_secret: don't build memfd_secret test on unsupported arches mm: fix endless reclaim on machines with unaccepted memory selftests/mm: compaction_test: fix off by one in check_compaction() mm/numa: no task_numa_fault() call if PMD is changed mm/numa: no task_numa_fault() call if PTE is changed mm/vmalloc: fix page mapping if vm_area_alloc_pages() with high order fallback to order 0 mm/memory-failure: use raw_spinlock_t in struct memory_failure_cpu mm: don't account memmap per-node mm: add system wide stats items category mm: don't account memmap on failure mm/hugetlb: fix hugetlb vs. core-mm PT locking mseal: fix is_madv_discard()
