Merge branch 'for-3.11-cpuset' of git://

Pull cpuset changes from Tejun Heo:
 "cpuset has always been rather odd about its configurations - a cgroup
  right after creation didn't allow any task executions before
  configuration, changing configuration in the parent modifies the
  descendants irreversibly and so on.  These behaviors are inherently
  nasty and almost hostile against sharing the hierarchy with other
  controllers making it very difficult to use in unified hierarchy.

  Li is currently in the process of updating the behaviors for
  __DEVEL__sane_behavior which is the bulk of changes in this pull
  request.  It isn't complete yet and the behaviors will change further
  but all changes are gated behind sane_behavior.  In the process, the
  rather hairy work-item punting which was used to work around the
  limitations of cgroup descendant iterator was simplified."
