This kind of arch specific stuff still shouldn't need to
bubble right up to the driver level  I'd think a driver
should be able to include <asm/irq.h> and have whatever
arch specific goo like this be present.

So maybe this kind of magic should be in arch/m68k/include/asm/irq*
instead of here?

And on re-reading the comments in the other part of the patch, i.e.
"...emulates the card interrupt via a timer"  --perhaps the driver
should be just fixed to support generic netpoll, instead of adding
an arch specific thing that amounts to netpoll.  Then anyone can
attempt to limp along and use one of these ancient relics w/o IRQ.

Paul.
