| 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.

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.
