[PATCH] Remove even more stale references to Documentation/smp.tex

Randy cleaned out the bulk of these stale references to the now long gone
Documentation/smp.tex back in 2004. I followed this up with a few more
sweeps. Somehow, these have managed to sneak back in since.

I can't seem to figure out a contact point for M32R (no one listed in
MAINTAINERS!), but, these patches are only but trivial.
