we added uefi stub for hv, and want vm0 continue running under uefi env to boot other uefi payload (osloader or bzImage). during this, the uefi timer irq need be handled elegantly. there are 3 types for uefi timer: 1. 8254 based on IRQ0 of PIC 2. HPET based on IOAPIC 3. HPET based on MSI currently, we only support type 3 (HPET+MSI). But we are following a in-correct flow to handle this timer interrupt: - we set VMX_ENTRY_INT_INFO_FIELD directly if a timer interrupt happened before vcpu launching, this will make its vlapic mess up, which finally cause hpet timer stop. this patch remove this in-correct approach, the new approach patch will be followed by next patch.
