Let me reword that. It enables the nodes in the possible map.

When the 'numa.c' code is built with debug messages, and the system was
given that configuration by pHyp, yes, I did.

The debug message for each core thread would be something like,
removing cpu 64 from node 0
adding cpu 64 to node 8
repeated for all 8 threads of the CPU, and usually with the messages
for all of the CPUs coming out intermixed on the console/dmesg log.

In the sense that the nodes were defined in the device tree, that is correct.
In the sense that those nodes are currently deleted from node_possible_map in
'numa.c' by the instruction 'node_and(node_possible_map,node_possible_map,
node_online_map);', the nodes are no longer available to place memory or CPU.

Okay, I can try to insert code that extracts all of the nodes from the
ibm,associativity-lookup-arrays property and merge them with the nodes
put into the online map from the CPUs that were found previously during
boot of the powerpc code.

See attachment 'device-tree.log'. Note though that this boot of my test
system only has 2 nodes, 0 and 2.
