    No, the topology should at all time be independent of powersavings,
    current x86's topology depending on that is one of the biggest warts
    ever. Also sched_powersavings, doesn't actually exist anymore.

    The NHM-EP from your example should do just two levels since mc and cpu
    are identical, I guess we could add a pass that merges identical masks
    so you can still specify 3 levels if you want.

    The NUMA stuff is done automatically based on SLIT, so you don't need to
    go above the socket level.
