In non-NUMA configurations nb_numa_nodes is zero and we set 5th cell in ibm,max-associativity-domains to -1. That causes to stall Linux guests during boot after following line:
[ 0.000000] NUMA associativity depth for CPU/Memory: 4 Make last possible NUMA in property zero to correct support for non-NUMA guests.
