JFYI: vectors are not the same as hard interrupt numbers.
On ia64 they imply priority, which means that vector
numbers should be selected for their priority and not
have a 1-to-1 mapping with IRQ number.
On powerpc they mean absolutely nothing other than being
an index into an array.

It's better to use IRQs and not vectors to lookup int.
events by number.

FYI,
