This set of tries to optimize the TLB code on 8xx even
more. If they work, it should be a noticable performance
boost.

I would be very happy if you could test them for me.

 - v2:
   Since Scott has done some testing of these patches I resend
   them with my SOB.
   Scott, can you "bless" these patches too?

Joakim Tjernlund (4):
  8xx: Optimze TLB Miss handlers
  8xx: Avoid testing for kernel space in ITLB Miss.
  8xx: Don't touch ACCESSED when no SWAP.
  8xx: Use SPRG2 and DAR registers to stash r11 and cr.
