Currently, the load_balance trigger will be called in timer for periodic tick, or dynamic tick. In periodic tick, the cpu is waked, so do load_balance is not cost much. But in dynamic tick. we'd better do power policy suitable scenario checking in nohz_kick_needed(), and then do nohz_balancer_kick on least but non-idle cpu if possible. that reduce the idle cpu waking chance.
