This would all be much simpler, if PAPR's representation of NUMA
distances weren't so awful. Somehow it manages to be both so complex
that it's very hard to understand, and yet very limi

NUMA nodes corresponding to GPU memory currently have the same
affinity/distance as normal memory nodes. Add a third NUMA associativity
reference point enabling us to give GPU nodes more distance.
Before, `numactl -H` output in a guest with 4 GPUs (nodes 2-5):
node distances:
node 0 1 2 3
