While this patch might still get in since it actually fixes a problem,
the normal way of expressing interrupt bindings on linux is via a
cpumask. I recommend you do that too and update the affinity mask in
the irq_desc even if you don't provide a set_affinity() callback to
do runtime change just yet (and maybe never due to HV limitations).

Ben.
