Here are my latest code to fixup 8xx's TLB code. This code needs some serious testing before it can be commited. The "8xx, fault: Add some debug code to do_page_fault()" is purely a debug check and will be removed/disabled when this series appear stable.
Scott and Rex, please disregard other patches from me and try these out instead.
