Merge tag 'mm-hotfixes-stable-2026-10-07-21-48' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull MM fixes from Andrew Morton:

 - Update .mailmap entries for Andy Yan and John Garry

 - Fix read-only MAP_SHARED /dev/zero mappings so they retain
   shared-file semantics instead of being treated as anonymous memory,
   also avoiding a CONFIG_DEBUG_VM assertion

 - Fix 32-bit build warnings in the hugetlb-mmap selftest caused by
   using the wrong printf format for size_t values

 - Fix a boot-time crash when early function tracing causes CPA to free
   kernel page tables before the workqueues used for deferred freeing
   are available

 - Fix two MREMAP_DONTUNMAP locked_vm accounting leaks: one caused by
   an mlock-on-fault VMA self-merging, and one caused by partially
   remapping a locked VMA
