    Pull cgroup fixes from Tejun Heo:

     - Fix circular locking dependency in cpuset partition code by
       deferring housekeeping_update() calls to a workqueue instead
       of calling them directly under cpus_read_lock

     - Fix null-ptr-deref in rebuild_sched_domains_cpuslocked() when
       generate_sched_domains() returns NULL due to kmalloc failure

     - Fix incorrect cpuset behavior for effective_xcpus in
       partition_xcpus_del() and cpuset_update_tasks_cpumask()
       in update_cpumasks_hier()

     - Fix race between task migration and cgroup iteration
