Every processor has a local node on which it runs. The kernel places
memory used by the processor on the local node. Even if we allow
nodes without memory: We still need to associate a "local" node to the
processor. If that is across some NUMA interlink then it is going to be
slower but it will work.
AFAIK It seems to be better to explicitly associate a memory node with a
processor during bootup in arch code.
Various kernel optimizations rely on local memory. Would we create
a special case here of a pglist_data structure without a zones structure?
It seems that the contents of pglist_data are targeted to a memory node.
If we do not have a pglist_data structure then the node would not exist
for the kernel.
What would the benefit or difference be of having nodes without memory?
