    To apply the O(1) scheduler you only need to backout the dyn-sched and
    numa-sched patches first (dyn-sched will be definitely obsoleted by the
    O(1) scheduler, numa-sched should be changed like Mike described a few
    weeks ago but probably O(1) will just work better than my current
    numa-sched). There are no other changes to the scheduler, the
    child-first is an optimization and parent-timeslice is an important
    bugfix.
