Merge branch 'akpm' (patches from Andrew)
Merge more updates from Andrew Morton: "The rest of MM" * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (101 commits) mm, compaction: simplify contended compaction handling mm, compaction: introduce direct compaction priority mm, thp: remove __GFP_NORETRY from khugepaged and madvised allocations mm, page_alloc: make THP-specific decisions more generic mm, page_alloc: restructure direct compaction handling in slowpath mm, page_alloc: don't retry initial attempt in slowpath mm, page_alloc: set alloc_flags only once in slowpath lib/stackdepot.c: use __GFP_NOWARN for stack allocations mm, kasan: switch SLUB to stackdepot, enable memory quarantine for SLUB mm, kasan: account for object redzone in SLUB's nearest_obj() mm: fix use-after-free if memory allocation failed in vma_adjust() zsmalloc: Delete an unnecessary check before the function call "iput" mm/memblock.c: fix index adjustment error in __next_mem_range_rev() mem-hotplug: alloc new page from a nearest neighbor node when mem-offline mm: optimize copy_page_to/from_iter_iovec mm: add cond_resched() to generic_swapfile_activate() Revert "mm, mempool: only set __GFP_NOMEMALLOC if there are free elements" mm, compaction: don't isolate PageWriteback pages in MIGRATE_SYNC_LIGHT mode mm: hwpoison: remove incorrect comments make __section_nr() more efficient ...
