Merge branch 'akpm' (patches from Andrew)
Merge misc updates from Andrew Morton: - a few hotfixes - various misc updates - ocfs2 updates - most of MM * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (108 commits) mm, memory_hotplug: move movable_node to the hotplug proper mm, memory_hotplug: drop CONFIG_MOVABLE_NODE mm, memory_hotplug: drop artificial restriction on online/offline mm: memcontrol: account slab stats per lruvec mm: memcontrol: per-lruvec stats infrastructure mm: memcontrol: use generic mod_memcg_page_state for kmem pages mm: memcontrol: use the node-native slab memory counters mm: vmstat: move slab statistics from zone to node counters mm/zswap.c: delete an error message for a failed memory allocation in zswap_dstmem_prepare() mm/zswap.c: improve a size determination in zswap_frontswap_init() mm/zswap.c: delete an error message for a failed memory allocation in zswap_pool_create() mm/swapfile.c: sort swap entries before free mm/oom_kill: count global and memory cgroup oom kills mm: per-cgroup memory reclaim stats mm: kmemleak: treat vm_struct as alternative reference to vmalloc'ed objects mm: kmemleak: factor object reference updating out of scan_block() mm: kmemleak: slightly reduce the size of some structures on 64-bit architectures mm, mempolicy: don't check cpuset seqlock where it doesn't matter mm, cpuset: always use seqlock when changing task's nodemask mm, mempolicy: simplify rebinding mempolicies when updating cpusets ...
