[Patch] Fix IDLE issue with sedf scheduler on IA64
Hi, Dan,
This patch fixes strange behavior on IA64, that IDLE is
scheduled more than Dom0 with default sEDF scheduler.
The key point is reprogram_ac_timer at the end of ac_timer
dispatcher, which programs local apic timer with expire of next ac_timer
on x86. Higher precision lapic timer can trigger ac_timer more precisely
than simply done in PIT interrupt handler. That works perfectly on x86
