I am quite happy with the fact that you put the base device-tree based 
NUMA patches on for-next/core.

There is only a very small adjustment to those in the ACPI-NUMA patches 
([PATCH v5 06/14] arm64, numa: rework numa_add_memblk()), so I think we 
are fine as far as that goes.

My plan is to post a v6 later today that adjusts some of the messages 
printed out and adds some Reviewed-by and Acked-by that were accumulated.

David.
