I've been sidetracked to some other stuff so for now Paul (CC) is taking
over my interrupt patches.
We initially changes IRQ_CREATE_IRQCHIP to take an argument but that was
causing an x86 ABI breakage (ioctl number changing). So we'll probably
be creating a new one.

The main problem we haven't sorted out yet is how to replace some of the
horrors related to mapping interrupts that have tendrils all the way
into virtio-pci etc... in kemu that don't apply to use (well mostly) and
the interaction with in-kernel generated interrupts to avoid going
through qemu for vhost ec...
Cheers,
Ben.
