  mailmap: update entry for Andy Yan (2026-10-06 16:44:19 -0700)

----------------------------------------------------------------
7 hotfixes.  4 are cc:stable.

- 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.
