Another beneft of the new generic interrupt code will be for weird
multiplex devices like IOC3 which basically want to be treated as if they
have an interrupt controller on the PCI card itself. The latest code now
enables the IOC3 metadriver to support that in a portable way. The only
thing that's still missing is a portable way to allocate an interrupt
number.

One step after another.
