Subject: [PATCH v3 0/2] Invert cpu_hotplug_lock and cpuset_mutex locking order.

This patch does following
	1- Remove circular dependency deadlock by inverting order of
cpu_hotplug_lock and cpuset_mutex.
	2- Make cpuset_hotplug_workfn() synchronous for cpu hotplug path.
For memory hotplug path it still gets queued as a work item.

  cgroup/cpuset: remove circular dependency deadlock
  cpuset: Make cpuset hotplug synchronous
