Merge branch 'akpm' (incoming fixes from Andrew)
Merge misc fixes from Andrew Morton: "The audit fixes have been floating around for a while - Al and Eric aren't responding to either myself or Kees so I asked Kees to re-review them and here they are." * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (22 commits) lib/rbtree.c: avoid the use of non-static __always_inline MAINTAINERS: Omar had moved mm: compaction: partially revert capture of suitable high-order page linux/audit.h: move ptrace.h include to kernel header kernel/audit.c: avoid negative sleep durations audit: catch possible NULL audit buffers audit: create explicit AUDIT_SECCOMP event type MAINTAINERS: fix a status pattern MAINTAINERS: fix arch/arm/plat-omap/include/plat/omap_hwmod.h mm: thp: acquire the anon_vma rwsem for write during split mm: mmap: annotate vm_lock_anon_vma locking properly for lockdep lockdep, rwsem: provide down_write_nest_lock() arch/mn10300/Kconfig: select CONFIG_GENERIC_ATOMIC64 mm: bootmem: fix free_all_bootmem_core() with odd bitmap alignment mm: use aligned zone start for pfn_to_bitidx calculation fs/exec.c: work around icc miscompilation mm: compaction: fix echo 1 > compact_memory return error issue mm: memblock: fix wrong memmove size in memblock_merge_regions() drivers/video/ssd1307fb.c: fix bit order bug in the byte translation function mm: migrate: check page_count of THP before migrating ...
