In c/s 20650:b543acc1aaad you made clear_IO_APIC() call both clear_IO_APIC_pin() and clear_IO_APIC_raw(), and I don't really follow why the former would be necessary here - the only code paths we care about are boot and shutdown/crash, and hence all we want is clearing the actual IO-APIC RTEs (without regard to interrupt re-mapping). Furthermore, even clear_IO_APIC_pin() is only called during early boot, so it would seem to me that we should only need the "raw" variant. The context of the question is the need to add some extra code here to clear the remoteIRR bit if still set (e.g. during a crash), as that bit remaining set can otherwise lead to later confusion (during crash handling in the secondary kernel, and when booted through kexec in Xen itself).
