I was thinking about moving entirely away from any bits of genirq for
this. We shouldn't really be mixing these two things together by
nabbing some of the IRQ numberspace for this.
Looking at this code, I'm thinking about taking this further, and
santising the whole thing... though that's not going to be a quick
change.
