The patch basically looks fine to me and I put it in my 2.5 tree with
a few small changes to take advantage of the new per-CPU scheme
(avoids clutter in asm/processor.h). Also, I think it's sufficient to
call delayed_flush_tlb() in get_new_mmu_context(), as we just need to
make sure that the TLB does get flushed before. Or did this not work
for some reason?
