Hi folks,
As pointed out by Barry in [1], there are topologies out there that struggle to go through the NUMA distance deduplicating sort. Included patch is something I wrote back when I started untangling this distance > 2 mess.
It's only been lightly tested on some array of QEMU-powered topologies I keep around for this sort of things. I *think* this works out fine with the NODE topology level, but I wouldn't be surprised if I (re)introduced an off-by-one error in there.
@Barry feel free to test / edit this as you see fit.

HTH.
