Thanks for putting this together. I had a minor comment but the patches
look fine to me. We still need an ack from Rob on the DT patch and I can
queue the series for 5.11.

Could you please also test the patch below on top of this series? It's
the removal of the implied DMA offset in the max_zone_phys()
calculation.
