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?
  
I've double checked - that hunk should not actually have been in the 
patch at all. My bad ...
With all arch-specific interrupt tweaks (aside from the  interrupt 
flags) now removed from the driver, the definition wasn't actually used 
any longer in the main driver file.

The non-standard interrupt flag will still be required for those users 
that decide to wire up the card interrupt line to, for example, the 
modem serial port's ring input.
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.
  
I had in fact implemented that as a fallback option earlier, and it 
turned out to be quite a bit slower that way.
If that's the preferred option, I'll add netpoll to the 8390 driver and 
resubmit.

Thanks,

  Michael
