To split hairs, they're not currently off node - as they have to reside in
ZONE_NORMAL, I can't make them so until I have the nonlinear stuff
(or equivalent). But they ought to be on their home node, so your point
is pretty much the same ;-) AFAIK, all other NUMA arches use the local
lmem_map already.

Is zone_numa a typo for zone_normal, or did I lose track of the conversation
at some point? I'm not sure I grok the last sentence of yours ....
