This adds another level of indirection, I think. Currently cpu_to_node
is a simple inliner. After the patch it would be a real function with
all the associate overhead. Can you share a bloat-o-meter output here?

Regardless, I don't think that the approach is correct. As per your
description, some initialization functions erroneously call
cpu_to_node() instead of early_cpu_to_node() which exists specifically
for that case.
I checked the code again.
The sparc, mips an

Is there a fundamental reason to have early_cpu_to_node() at all?
The early_cpu_to_node does not work on some ARCHs (which support the NUMA),
such as
