That's a good question, and I don't have a proper answer right now...

However, per cpu or not, the affinity still needs to be set for that 
interrupt. It seemed to me that the desc->affinity_hint was just a way 
to keep track of the interrupt affinity when it gets set through 
irq_set_affinity_hint.

Is that not the case?
