KVM: irq ack notification
Based on a patch from: Ben-Ami Yassour <benami@il.ibm.com> which was based on a patch from: Amit Shah <amit.shah@qumranet.com> Notify IRQ acking on PIC/APIC emulation. The previous patch missed two things: - Edge triggered interrupts on IOAPIC - PIC reset with IRR/ISR set should be equivalent to ack (LAPIC probably needs something similar).
