    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,
