The functions are used only by the /dev/mem driver so really they belong to
us, if you choose to build with our alternative driver. The original
interface is unimplementable over Xen (since we do not have 1:1 mappings of
everything). If those changes get merged upstream I would expect a size
parameter would get added to the function in upstream too.
