CPUIDLE: Port Linux menu governor to replace the initial ladder governor The ladder governor has long pro/demotion delay shortcome while applying to tickless mode, because it needs to count usage. Menu governor chooses the next state simply via break-event prediction including the factors of next timer event & last residency time etc, so it would have faster response speed.
