I'm not sure which tree you based this on, but I got some conflicts
in pte-8xx.h using Ben's merge branch.

After resolving the conflict, without adding tlbil_va in do_page_fault(), I
get the same stuck behavior as before.  With tlbil_va, I get this (not sure
if it's related to using the wrong base tree):
