This would be much cleaner if you use virq_to_hw() and add a
definition of virq_to_hw to the asm-ppc headers, so that you can avoid
putting ifdefs in code.

Also, it seems a bit bogus to be using the hardware interrupt number
directly here.

Is it just 82xx that uses this driver, or do other chips (85xx?) use
it too?

Paul.
