Adding the relevant people - while the might be irrelevant, at least
mips and sparc have some giant memory systems.  And I'd really like
to see the arch-specific GUP implementations to go away for other
reasons, as we have a few issues to sort out with GUP usage now
(we just had discussions at LSF/MM), and the less implementations we
have to deal with the better.
