While it would be nice to simply make request_percpu_irq() take
an affinity mask, the churn is likely to be on the irritating side
given that most drivers do not give a damn about affinities.

Only 37 instances. I'd have been tempted to do it anyway :)

I'm leaving this as an exercise for people who enjoy cross-subsystem
patch series!

So take the more innocuous path to provide a helper that parallels
request_percpu_irq(), with an affinity as a bonus argument.

Yes, request_percpu_irq_affinity() is a bit of a mouthful.
