It would be very easy to collapse the four IPIs onto one event channel plus
a bitmask of IPI reasons. Then that would be a much more economical two
event channels per CPU. And the change is a hell of a lot easier to
implement than extensible event channels. I bet it could be knocked together
in an hour.
