If you just use the proper assembler instructions for the mttb/mftb 
variants,
the assembler will chose the right encoding for the processor model.

This is why I don't like people just arbitrarily going through the
manuals and generating such #defines.  If we don't use something,
let's not define it.  How are you going to test a patch to "fix" this 
stuff
if it isn't used?  Just delete it and forget it.

Thanks.
