The m68knommu arch should be easy to fix up. Here is a first pass

Dunno if you noticed, Greg, but you've already had a removal patch
submitted some time ago...

I had forgotten about that patch... But if you follow the email
trail I had to drop it soon after, it caused user space to lock
up. I let Steven know (in that same thread) but he never came
back with any fixes/updates.

(That patch also added support for edge triggered GPIO interrupts,
and that may well have been the source of the problems).

Thanks
Greg

(noticed this while searching for __do_IRQ related stuff in my email
last night.)

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.
