[Xen-devel] [PATCH]enhance cpuidle pit broadcast

["Wei, Gang" <gang.wei@xxxxxxxxx>]

This patch reprog LAPIC timer in pit_broadcast_exit, to remove possible
timer expiring delay caused by deep C state LAPIC 
timer stopping.

Maybe later we can consolidate common logic for broadcast enter/exit
better, to avoid duplicated code. But for now let's leave it this way.
