    Thanks Suresh!

    We have verified that sched_mc_power_savings works well in mainline and
    -tip tree, only sched_smt_power_savings broken.

    Sorry. My proposed patch last night still need be refreshed. After I closely look
    at SD_PREFER_SIBLING logic, there is possible a fighting which Peter has
    mentioned it.

    I will post a update patch soon.
