    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."
