Thread-topic: IO_APIC in para-guest
Keir:
 When thinking more about IO_APIC virtualization in Itanium,
 I got a confuse: How is io_apic.c used in xenlinux (X86)?
 It looks like all the machine resource of io_apic is handled in 
xen (xen/arch/x86/irq.c), and the PIRQ based on event channel
 can be handled by pirq_type in linux/arch/xen/kernel/evtchn.c 
pretty well? Then what is the function of file io_apic.c? 
thx,eddie
