This patch should re-base with latest kernel; otherwise it will have
conflict with below commits:

827a5ae sched / idle: Call default_idle_call() from cpuidle_enter_state()
faad384 sched / idle: Call idle_set_state() from cpuidle_enter_state()
bcf6ad8 sched / idle: Eliminate the "reflect" check from cpuidle_idle_call()
82f6632 sched / idle: Move the default idle call code to a separate function

Thanks,
Leo Yan
