    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.

    Ian.
