I'm dropping this change from this patch because if we go with it,
we'll have to change all callsites of node_to_amd_nb which would cause
unnecessary churn.

So, I've applied the final patchset and uploaded a branch here:

git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git numascale

Please give it a run on both configurations and let me know if something
is still amiss.

Thanks.
