Merge branch 'akpm' (patches from Andrew) 

Merge misc fixes from Andrew Morton:
 "The gcc-4.4.4 workaround has actually been merged into a KVM tree by
  Paolo but it is stuck in linux-next and mainline needs it"

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  arch/x86/kvm/mmu.c: work around gcc-4.4.4 bug
  sched, numa: do not hint for NUMA balancing on VM_MIXEDMAP mappings
  zsmalloc: fix a null pointer dereference in destroy_handle_cache()
  mm: memcontrol: fix false-positive VM_BUG_ON() on -rt
  checkpatch: fix "GLOBAL_INITIALISERS" test
  zram: clear disk io accounting when reset zram device
  memcg: do not call reclaim if !__GFP_WAIT
  mm/memory_hotplug.c: set zone->wait_table to null after freeing it
