The end result looks good, but you should consider re-ordering this
patch set.
That would clean things up and make review much easier.
Adding code first and then removing it later on in the same patch set is
not a good practice.

Christian.

TLBs invalidation was removed from gmc_v9 and gmc_v10 files.
This implementation has been moved to kiq_pm4_funcs calls.
