That's a fairly evil hack. It will break again when we clean up the kvm
irqchips (not to speak of side effects in non-irqchip/non-kvm mode).

Why not hook into the kvm irqchip directly? Would keep generic code out
of this business until we have real irq pin manipulation in qemu.

Firstly, I did the minimal patch to get things working, as is my custom when fixing up merge/refactoring problems. Not that I often follow up with the clean fix.

Second, I'm not sure it's such a hack. Suppose our motherboard wired the PCI links to GSI16-19 (or GSI16-23, as we once wanted before we had MSI-X)? We'd need an API to access non-ISA interrupt lines.

So what's the clean fix here?  gsi_get_irq()?
