Jesse's patch

e2e64a932 genirq: Set initial affinity in irq_set_affinity_hint()

as it overwrites the previously set IRQ affinity mask for some of the
devices?

That's a good question. My gut feeling says yes.

IMHO if we think that this patch is still solving some issue other than
what Jesse has mentioned then perhaps we should reproduce that and fix it
directly from the request_irq code path.

Makes sense.

Thanks,
