This patch provides request_evtchn and free_evtchn, intended
to be used instead of bind_evtchn_to_irq/request_irq and
free_irq/unbind_evtchn_from_irq.  This allows architectures
to implement event channels as they see fit, not necessarily
using Linux IRQs.

Why would you not hook into the IRQ subsystem? This doesn't seem like a useful patch to me.
