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,

| operations become NOPs. So I don't see how it may

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.
