Keir, looks like in the below patch you had some typos - see lines
with (###): all the "tpm" should be "tp".
Hieu.

Change semantics of bind_evtchn_to_xxx and
unbind_evtchn_from_xxx. The bind now returns the IRQ
number on success. The unbind takes this as a parameter
instead of the event-channel port. Also, unbind closes
down the underlying event-channel port if it is still
live.
