It looks like the symptom is that the per-cpu areas are all allocated on node
0, is that all that goes wrong?

Yes, that's the symptom. I cc'd a few folks to see if they could help
indicate the performance implications of such a setup -- sorry, I should
have been more explicit about that.

Yeah, not sure it's really a bugfix but rather a performance optimization 
since cpu_to_node() with CONFIG_USE_PERCPU_NUMA_NODE_ID is only about 
performance.
