- The 4 patch series "mseal cleanups" from Lorenzo Stoakes erforms some
mseal cleaning with no intended functional change.
- The 3 patch series "Optimizations for khugepaged" from David
Hildenbrand improves khugepaged throughput by batching PTE operations
for large folios. This gain is mainly for arm64.
- The 8 patch series "x86: enable EXECMEM_ROX_CACHE for ftrace and
kprobes" from Mike Rapoport provides a bugfix, additional debug code and
cleanups to the execmem code.
- The 7 patch series "mm/shmem, swap: bugfix and improvement of mTHP
swap in" from Kairui Song provides bugfixes, cleanups and performance
improvememnts to the mTHP swapin code.
