Merge branch 'akpm' (patches from Andrew)
Merge second set of updates from Andrew Morton: "More of MM" * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (83 commits) mm/nommu.c: fix arithmetic overflow in __vm_enough_memory() mm/mmap.c: fix arithmetic overflow in __vm_enough_memory() vmstat: Reduce time interval to stat update on idle cpu mm/page_owner.c: remove unnecessary stack_trace field Documentation/filesystems/proc.txt: describe /proc/<pid>/map_files mm: incorporate read-only pages into transparent huge pages vmstat: do not use deferrable delayed work for vmstat_update mm: more aggressive page stealing for UNMOVABLE allocations mm: always steal split buddies in fallback allocations mm: when stealing freepages, also take pages created by splitting buddy page mincore: apply page table walker on do_mincore() mm: /proc/pid/clear_refs: avoid split_huge_page() mm: pagewalk: fix misbehavior of walk_page_range for vma(VM_PFNMAP) mempolicy: apply page table walker on queue_pages_range() arch/powerpc/mm/subpage-prot.c: use walk->vma and walk_page_vma() memcg: cleanup preparation for page table walk numa_maps: remove numa_maps->vma numa_maps: fix typo in gather_hugetbl_stats pagemap: use walk->vma instead of calling find_vma() clear_refs: remove clear_refs_private->vma and introduce clear_refs_test_walk() ...
