I am seeing this as well. Is the following commit premature?
e0eec24e2e19 ("memblock: make memblock_set_node() also warn about use of MAX_NUMNODES")
Maybe old ACPI tables and device trees need to catch up?
Left to myself, I would simply remove the WARN_ON_ONCE() from the above
commit, but I would guess that there is a better way.
Thanx, Paul
