This has been the plan for quite a while already.  Nowhere else than in
the TLB exception handler more details about exception handling,
pipeline structure, SMP etc. become visible and benchmarkable in that
few instructions.  Copy_page / clear_page have basically been a test
how well it'd work out - it did.  So from that point it was just a
question of who was going to bite the bullet and do the work and Thiemo
did.  Thanks!
