    Subject[RFC PATCH V4 0/5] cpuidle: Cleanup pm_idle and include driver/cpuidle.c in-kernel
    Date
    Changes in V4:
    * Implemented cpuidle driver for xen. Earlier pm_idle
    function pointer would be set to default idle. Now a cpuidle_driver
    encapsulating the idle routine is cleanly registered for this
    using cpuidle_register_driver API.

    * Implemented a cpuidle driver for apm_cpu_idle() as part of
    APM BIOS driver. Earlier APM BIOS driver would flip
    pm_idle function pointer to apm_cpu_idle.

    * This patch series applies on 2.6.38, and was tested on x86 system
    with multiple sleep states.

    Goal:
    This patch series tries to achieve the goal of having cpuidle manage
    all idle routine for x86. It removes pm_idle function pointer which
    causes problems discussed at http://lkml.org/lkml/2009/8/28/43 and
    http://lkml.org/lkml/2009/8/28/50.

    V1 of this series is at https://lkml.org/lkml/2010/10/19/449,
    V2 is at https://lkml.org/lkml/2011/1/13/98 and
    V3 is at https://lkml.org/lkml/2011/2/8/73
