Basically the first 5 patches deconstruct the whole situation, then the final patch throws the switch and makes PAGE_OFFSET variable based upon cpu type. I tested this patch series lightly on a T4. This obviously isn't enough to fully support 47-bit physical addresses yet, and I'll be looking into the page table issues next to take care of that. Signed-off-by: David S.
