So far so sane.

Not sure on this one. The whole msr_{read,write}_{safe,noser}() thing is
a royal pain. Also 'noser' reads to me as the noun that goes with 'to
nose' [he that noses (around), like baker: he that bakes].

I would much rather we just stick to the mnemonics here. All of this
really is about wrapping single instructions, no need to make it an
unreadable mess.
