[PATCH 2/4] CPUIDLE: Avoid remnant LAPIC timer intr while force hpetbroadcast
CPUIDLE: Avoid remnant LAPIC timer intr while force hpetbroadcast LAPIC will stop during C3, and resume to work after exit from C3. Considering below case: The LAPIC timer was programmed to expire after 1000us, but CPU enter C3 after 100us and exit C3 at 9xxus. 0us: reprogram_timer(1000us) 100us: entry C3, LAPIC timer stop 9xxus: exit C3 due to unexpected event, LAPIC timer continue running 10xxus: reprogram_timer(1000us), fail due to the past expiring time. ......: no timer softirq raised, no change to LAPIC timer. ......: if entry C3 again, HPET will be forced reprogram...
