uml: borrow const.h techniques
Suggested by Geert Uytterhoeven - use const.h to get constants that are usable
in both C and assembly. I can't include it directly since this code can't
include kernel headers. const.h is also for numeric constants that can be
typed by tacking a "UL" or similar on the end. The constants here have to be
typed by casting them.
So, the relevant parts of const.h are copied here and modified in order to
allow the constants to be uncasted in assembly and casted in C.
