History
Linus Torvalds a52a93358a 14 hotfixes. 10 are cc:stable. 11 are for MM. 
Five are DAMON fixes.  One fixes an arm64 contpte bug where DAMON can
 write past the end of a page-table page, resulting in memory corruption
 and possible crashes.
 
 Two are hugetlb fixes.  One fixes an mremap() address calculation bug
 which can panic x86-64.
 
 There's also a missing anon_vma publication barrier which can result in
 hung tasks, and a writeback fix to keep long cgroup writeback drains from
 delaying Tasks-RCU grace periods.
 
 The remainder are smaller fixes and maintenance changes.
