Merge branch 'suspend-to-idle'
* suspend-to-idle: cpuidle / sleep: Use broadcast timer for states that stop local timer cpuidle: Clean up fallback handling in cpuidle_idle_call() cpuidle / sleep: Do sanity checks in cpuidle_enter_freeze() too idle / sleep: Avoid excessive disabling and enabling interrupts
