I didn't realise you'd changed all the interrupt handlers too.  Good luck
with that :)

Is it a flag day or do we have a migration plan?  I'd have thought that we
could do a request_irq_new(irqreturn_t (*)(void *d)) and keep things
compatible?



<checks>

Actually, that tree applies reasonably sanely to the full -mm lineup. 
There are rejects of course, but they're easily fixed and a lot are due to
file motion which git will handle anyway,

The bigger problem is newly-added irq handlers which your patch doesn't
know about:

y:/usr/src/25> grep '^+.*request_irq[(]' patches/*.patch | wc -l
74

If we had a migration plan (ie: request_irq_new(), above) then this of
course wouldn't be a problem.
