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 Simplify
ppc_booke_xlate() part 1 and part 2 patches could be squashed together
but left them separate for easier review. This could still be continued
which I might do in the future but I had enough of it for now.
v6:
- Finish breaking up ppc_jumbo_xlate by MMU model as the TODO comment
said and remove it completely
- Add some more small clean ups
v5:
- drop sc patches from this series
- eliminate uninit warning work arounds and also get rid of
get_physical_address_wtlb() (one memset is still needed temporarily
but can be removed at the end)
- use function instead of macro
v4:
- Add a (probably redundant) check for MPC8xx case in ppc_xlate so we
don't have to care about it in lower levels
- Detangle BookE related functions from mmu_ctx_t to avoid some used
uninit work arounds and allow these to be moved out to mmu-booke.c
- Some other tweaks asked during review
v3:
- Address review comments from Nick
- Rebase on master
- Squashed some patches together
- Add some more patches I've done since last version
v2:
- Fix user mode issue in patch 1 by keeping old behaviour for user mode
- Add some more MMU clean up patches
