[PATCH v2 00/28] Misc PPC exception and BookE MMU clean ups

[BALATON Zoltan]

This series does some further clean up mostly around BookE MMU to
untangle it from other MMU models. It also contains some other changes
that I've come up with while working on this. The first 3 patches are
from the last exception handling clean up series that were dropped due
to some error on CI but I'm not sure if that was because of some CI
infrastructure problem or some problem with the patches as the error
did not make much sense. So these patches are only rebased now, I made
no other change to them until the issue is understood better. The rest
are new patches I've added since tha last series. Please review.

v2:
- Fix user mode issue in patch 1 by keeping old behaviour for user mode
- Add some more MMU clean up patches

Regards,
BALATON Zoltan
