Subject: add_timer_on and CONFIG_NO_HZ

Hi Thomas,
 It seems that when add_timer_on() is used to put a timer
on another cpu's timer queue, that remote cpu should be
made to reprogram its hardware APIC timer, when CONFIG_NO_HZ=y
and the new timer is put at the front of the timer wheel.

Regards,
Joe
