- 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.
