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.rp@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
