    SubjectRe: [RFC][PATCH 08/10] x86: Don't ack_APIC_irq() if lapic is disabled in GENERIC_INTERRUPT_VECTOR handler
    [Cyrill Gorcunov - Wed, Sep 16, 2009 at 12:58:35PM +0400]
    | Hi Sheng,
    | is there was some problem with it? I'm asking you
    | because if disable_apic=1 then any apic write/read
    | operations become NOPs. So I don't see how it may
    | hurt. But I could be missing something.
    | -- Cyrill

    Ah, I see -- it's due to your other patch...
    Hmm this makes all "disable apic" idea less
    general. And safety of ack_APIC_irq is now
    under suspicious.
