The m68knommu arch should be easy to fix up. Here is a first pass
patch. Tested and working on 1 board so far. I need to check all
the processor types, and test a few more to be sure :-)

m68knommu: stop using __do_IRQ

The use of __do_IRQ is deprecated, so lets stop using it.
Generally the interrupts on the supported processors here are
level triggered, so this is strait forward to switch over to
using the standard handle_level_irq flow handler.
