Maybe add something to explain why you are not simply mapping the existing memory to NUMA node 0 which is after all just a numbering scheme used by the kernel and can be used arbitrarily?
This could be seen more as a bug in the arch code during the setup of NUMA nodes. The two nodes are created by the firmwware / bootstrap code after all. Just do not do it?
