For example, we've already got both of these UINT constants in types.h Since this was written, we've got rather better about cleaning up xen/types.h, and extracting macros into xen/macros.h I think there's a good chance that the regular headers can now be used directly, or with minor tweaking. ~Andrew

Ok fine. Acked-by: Andrew Cooper <andrew.cooper3@citrix.com> However, doesn't this mean we can drop the block of typedefs in the context above? Happy to fold that in on commit. ~Andrew

Happy to fold that in on commit. Nope, that breaks differently. I'll put the patch in as-is and cleanup can come later. ~Andrew
