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?
Thanks,
