Seems like this driver should get the same threaded irq treatment as
the initiator side?
Indeed.
Turns out to be hard. The interrupt is allocated via
bind_interdomain_evtchn_to_irqhandler() which is not capable of threaded
irq handling. The underlying bind_interdomain_evtchn_to_irq() is not
exported, so I can't use it.
I'll try to change this, but until then I have to leave the irq handling
more or less the same.
