    Subject[v7 PATCH 0/7]: cpuidle/x86/POWER: Cleanup idle power management code in x86, cleanup drivers/cpuidle/cpuidle.c and introduce cpuidle to POWER.

    Please consider this for inclusion into the testing tree.

    This patchset introduces cpuidle infrastructure to POWER, prototyping
    for pSeries, and also does a major refactoring of current x86 idle
    power management and a cleanup of cpuidle infrastructure.

    Earlier discussions on the same can be found at:

    v6 -->
    v5 -->
    v4 -->
    v3 -->
    v2 -->
    v1 -->

    Changes in this version:

    * Earlier implementation maintained a list of cpuidle devices and
    the list was traversed to disable and enable the cpuidle devices
    when switching governors. This list is not necessary and is removed.
    Now, we get the per cpu structure cpuidle_devices and disable and
    enable it for each online cpu while switching governors.

    * Earlier iterations were buggy w.r.t the sysfs interface of the cpuidle.
    This iteration removes the bug in PATCH 1/7.

    * In PATCH 7/7, smt_snooze_delay was not being updated whenever it was
    changed through the sysfs interface. Provide a helper routine to
    update it.

    * In PATCH 7/7, the idle loops are renamed to denote the idle states
    to avoid any confusion.
