Pull cgroup fixes from Tejun Heo:
 "Quite a few fixes this time.

  Three locking fixes, all marked for -stable.  A couple error path
  fixes and some misc fixes.  Hugh found a bug in memcg offlining
  sequence and we thought we could fix that from cgroup core side but
  that turned out to be insufficient and got reverted.  A different fix
  has been applied to -mm"

* 'for-3.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
  cgroup: update cgroup_enable_task_cg_lists() to grab siglock
  Revert "cgroup: use an ordered workqueue for cgroup destruction"
  cgroup: protect modifications to cgroup_idr with cgroup_mutex
  cgroup: fix locking in cgroup_cfts_commit()
  cgroup: fix error return from cgroup_create()
  cgroup: fix error return value in cgroup_mount()
  cgroup: use an ordered workqueue for cgroup destruction
  nfs: include xattr.h from fs/nfs/nfs3proc.c
  cpuset: update MAINTAINERS entry
  arm, pm, vmpressure: add missing slab.h includes
