Well, I specifically didn't say "ack": I don't really mind the change, but I'm also not eager see it go in. Not seeing a problem with it doesn't really mean there's none lurking - type changes in public interfaces are always an at least slightly risky business. Jan

For x86 there is no change here since: xen/include/public/arch-x86/xen.h:typedef unsigned long xen_ulong_t; Also the tools/include/xen-foreign checks show no change in the size of things on x86. On ARM the change is deliberate, if there is any fallout we can fix it. Ian.
