Both are (relatively) arbitrary, small numbers and making them equal would simplify things a bit. The only downside would be that the Linux irq numbers would no longer be equal to the IA-64 vectors, so that the irq->vector translation would have to go through a table-lookup even on "small" systems. The performance effect of this should be completely trivial (i.e., I bet it's not measurable). Comments? Takers? ;-) --david
