Revert a commit from more than six months ago when the fix is probably a 
small patch in cpuset_attach()?  I think we can do better than that.

This may not have introduced a new feature, but it was a worthwhile change 
to avoid the old cpuset_update_task_memory_state() hooks in mempolicy, 
page allocator, etc. code that could block on callback_mutex for iterating 
the hierarchy.
