I suggested to drop the property numa-node-id from every node (not only 
memory one). So DOM0 will think it is running a non-NUMA platform.
From my knowledge this is working on x86, and I don't understand why 
this would be an issue on ARM. If you think the device may not work, 
please explain why.
