Yes, this looks fine to me. Looks like a good cleanup, and moves more
code to generic headers rather than having arch-specific stuff.

Ben, can you check that this is ok on powerpc? Who else should
double-check this due to having been involved in tlb flushing? But I
think this is good to go, modulo checking other architectures for
sanity.
