Merge tag 'mm-hotfixes-stable-2026-09-27-19-12' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull MM fixes from Andrew Morton:

 - Fix module loading incorrectly returning success after alloc_tag
   codetag setup failed

 - Restore MADV_COLLAPSE semantics for shmem so forced collapse ignores
   the shmem THP/mTHP sysfs settings

 - Make alloc_tag UAPI structure padding explicit

 - Fix DAMON schemes unexpectedly stopping after quotas are disabled
   through the online parameter update interface

 - Fix a false SW_TAGS KASAN invalid-access report when freeing vmapped
   task stacks

 - Split the MEMORY MANAGEMENT - MEMORY POLICY AND MIGRATION MAINTAINERS
   entry into separate MIGRATION and NUMA PLACEMENT entries

 - Move memory tiering maintenance under NUMA PLACEMENT

 - Add Gregory Price as a NUMA PLACEMENT co-maintainer

 - Add Heming Zhao as an ocfs2 reviewer

 - Fix mmap_prepare() state being copied onto a merged VMA rather than
   only onto a newly allocated VMA
