The first use of this functionality is to update the vlapic trigger-mode register when the IOAPIC pin configuration is changed. Prior to this change we would update the TMR in the virtual-APIC page at the time of interrupt delivery. But this doesn't work with Posted Interrupts because there is no way to program the EOI_exit_bitmap[] in the VMCS of the target at the time of interrupt delivery. Discussed with: grehan@
