    KVM: irq ack notification · f5244726

    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).
