Unfortunately, this expands to 0xffffffff on 32-bit systems and 0xffffffffffffffff on 64-bit systems; with the result that while 32-on-32 and 64-in-64 work fine, 32-on-64 (also known as "compat mode") is broken. This patch makes the definition consistent across architectures. In so doing, it will break old-32-bit-on-new-Xen, and vice versa; but this was seen as an acceptable thing to do.
