[Xen-devel] [PATCH] Fix 32bit SMP Vista bootup issue

["Yang, Xiaowei" <xiaowei.yang@xxxxxxxxx>]

As we know, 32bit SMP Vista uses RTC as periodic timer for timekeeping.
It programs ioapic to deliver RTC interrupt to vcpu0. When vcpu0 handles
RTC interrupt, it sends IPI with the same vector number ioapic uses for
RTC entry to notify other processor to do time related work, like
scheduling. hvm_interrupt_post() mistakes it for another timer interrupt
and does some extra unwanted work, which makes RTC read result error
sometimes. This patch fixes it.
