Merge branch 'akpm' (patches from Andrew)
Merge misc updates from Andrew Morton: "Bite-sized chunks this time, to avoid the MTA ratelimiting woes. - fs/notify updates - ocfs2 - some of MM" That laconic "some MM" is mainly the removal of remap_file_pages(), which is a big simplification of the VM, and which gets rid of a *lot* of random cruft and special cases because we no longer support the non-linear mappings that it used. From a user interface perspective, nothing has changed, because the remap_file_pages() syscall still exists, it's just done by emulating the old behavior by creating a lot of individual small mappings instead of one non-linear one. The emulation is slower than the old "native" non-linear mappings, but nobody really uses or cares about remap_file_pages(), and simplifying the VM is a big advantage. * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (78 commits) memcg: zap memcg_slab_caches and memcg_slab_mutex memcg: zap memcg_name argument of memcg_create_kmem_cache memcg: zap __memcg_{charge,uncharge}_slab mm/page_alloc.c: place zone_id check before VM_BUG_ON_PAGE check mm: hugetlb: fix type of hugetlb_treat_as_movable variable mm, hugetlb: remove unnecessary lower bound on sysctl handlers"? mm: memory: merge shared-writable dirtying branches in do_wp_page() mm: memory: remove ->vm_file check on shared writable vmas xtensa: drop _PAGE_FILE and pte_file()-related helpers x86: drop _PAGE_FILE and pte_file()-related helpers unicore32: drop pte_file()-related helpers um: drop _PAGE_FILE and pte_file()-related helpers tile: drop pte_file()-related helpers sparc: drop pte_file()-related helpers sh: drop _PAGE_FILE and pte_file()-related helpers score: drop _PAGE_FILE and pte_file()-related helpers s390: drop pte_file()-related helpers parisc: drop _PAGE_FILE and pte_file()-related helpers openrisc: drop _PAGE_FILE and pte_file()-related helpers nios2: drop _PAGE_FILE and pte_file()-related helpers ...
