I'm going to hold off giving this a final review until we have that
previous VTTBR_X patch sorted out.

Given the number of open questions in that one, I recommend you factor
that patch out of this patch set, get that sorted out first, and then
send a new version of this patch set once we have an agreement on the
other patch.
