Applied 1-8 to cgroup/for-7.0-fixes with the following minor fixups:

- 5/8: Removed a duplicate test entry that resulted from the "S+"
  removal (two previously-different lines becoming identical).

- 8/8: Fixed typos in commit message ("essentally" -> "essentially",
  "beforce" -> "before") and code comment ("top_cpuset_mutex" ->
  "cpuset_top_mutex").

This has gone through more than enough iterations. We can resolve further
issues if there's any incrementally.

Thanks.
