But which ones are NUMA with node-scattered physical memory? sn2 for
sure. DIG, zx1 are not, for sure. I'm not certain about NEC or Bull.
So I'm not convinced that it works for all possible physical memory
layouts.

Yes. Actually, I'm concerned about size, too. It would be good to
have an init-mem-like approach so that we can free all the code/data
for unused machvec code.
