We have a pretty strong no unused hooks policy for the linux kernel, as we don't want to put in unused code. This is more of a restructuring than actual hooks though, so it's on a borderline. I'd really prefer to get Xen/ia64 and the Xen common code merged soon though - it's in a much better shape then Xen/i386 and would give the common code some badly needed exposure.
