This patch does nothing on machines with simple NUMA topologies.

Supposed to make that true?
It doesn't. That test is a !numa test, not a fully connected test.
Look at patch 1/4. I only set max_distance to !LOCAL_DISTANCE
if the system has multiple different distances in the SLIT
table.
I guess that needs to be cleaned up :)
