I've considered doing something like that as well, but I don't think
that this is a good idea.

I'd argue that way as well. The whole point of the "typedef { u{32|64}
l? } l?_pgentry_t" types and the access macros is to make the _compiler_
notice bugs, so they can't creep into the code base in the first place
because gcc refuses to compile the buggy code ;)
