I'm OK with the original name. The point is not that we're getting
events from evtchns, but that the mechanism allows us to receive them
without having to touch the APICs and suffer the vmexits. To the rest
of the kernel, events delivered via the platform device are really just
ordinary interrupts from an ordinary device which happens to have a
particularly elaborate "interrupt source" register.
