Ahhh... yes. I should have updated the lsslot man page along with this.
Thanks for pointing that out.

The associativity is cpu <=> memory affinity, this tells us which node
the memory is on.

Section(s) refers to the memory sections in sysfs, i.e.
/sys/devices/system/memory/memoryXXX.

LMB stands for Logical Memory Block.
