When we were chasing the TLB crash recently for a while I was suspecting
the default get_user_fast implementation so I ported gup.c from x86 but I
never really finished it, so thanks for ridding me of one item from my
to do list.

This probably wants some more testing in particular on 32-bit systems with
64-bit pagetables such as some Alchemy configurations or 32-bit kernels
on Sibyte systems.

I fixed up a reject in arch/mips/mm/Makefile due to whitespace differences
and queued the patch for 3.3.

Have you made any benchmarks of the new gup.c?

Thanks,

  Ralf
