Rafael J. Wysocki 0d94039fab cpuidle: Select a different state on tick_broadcast_enter() failures 
If tick_broadcast_enter() fails in cpuidle_enter_state(),
try to find another idle state to enter instead of invoking
default_idle_call() immediately and returning -EBUSY which
should increase the chances of saving some energy in those
cases.
