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.
