Hi Cyril,
Thanks for posting fixes patch set again. I have in fact used your
previous patch series on a real LPAE system with split memory banks in
both 32-bit and 36-bit physical addresses. I compared your below patches
with previous version, and don't see significant changes. Hence you can use
Tested By: Subash Patel <subash...@samsung.com>
for this series as well. In the meantime, I have used the pa/va patching
from v3, but haven't tested any performance numbers on it. But I will
wait for your next reworked version.
Regards,
Subash

This series is a repost of the LPAE related changes in preparation for the
introduction of the Keystone sub-architecture. The original series has now
been split, and this particular series excludes the earlier changes to the
runtime code patching implementation. Earlier versions of this series can be
found at [1], [2], [3] and [4].
