As HP300 and VME turned out to be really easy (but untested due to lack of
hardware), I added two more commits:

[PATCH 17/18] m68k/hp300: Convert HP9000/300 and HP9000/400 to genirq
[PATCH 18/18] m68k/vme: Convert VME to genirq

These all pass non-NULL handlers to m68k_setup_{auto,user}_interrupt().
