Can you tell us why mpic should be in kernel? Is it used often by modern
guests or may be they prefer MSI for interrupt delivery (hmm may be MSIs
are delivered through mpic too)? On x86 we actually would've preferred
to move PIC/IOAPIC form the kernel and leave only LAPIC there (but for
historical reasons creation of PIC/IOAPIC/LAPIC are bundled together)
hence my question.
