Sorry, I think this confusion might actually be my fault and Hoan has just
been implementing my vague suggestion here:

https://lore.kernel.org/linux-arm-kernel/20190625101245.s4vxfosoop52gl4e@willie-the-truck/

If the preference of the mm folks is to leave CONFIG_NODES_SPAN_OTHER_NODES
as it is, then we can define it for arm64. I just find it a bit weird that
the majority of NUMA-capable architectures have to add a symbol in the arch
Kconfig file, for what appears to be a performance optimisation applicable
only to ia64, mips and sh.

At the very least we could make the thing selectable.
