I'm about to followup with an initial stab at some cleanups which are
made possible by these core changes, including hanging the per-irq info
off the handler_data.

These patches are on top of recent Linus master tree plus Konrad's
swiotlb-xen tree and Stefano's PVHVM tree since the latter in particular
touches the same area.
