This is a patch removes an OProfile dependency on the spufs module.
This was causing a problem for multiplatform systems that are
built with support for Oprofile on Cell but try to load the
oprofile module on another system.

A few people have asked me for including this one, I'd like
it to get that in still. It was broken ever since you could
enable support for spu oprofile.
Jeremy, please ack the spufs changes if you are ok with the patch.
Sorry for delaying this patch so long on my side everyone.
