It's a bit convoluted as an API to get the fullfree memory on a Node, maybe this should be separated as a different APIas people looking for this information may not think about looking at NUMA special entry points. We don't have currently a simple API toget the free memory on a Node, maybe that should be added.
Having the separate semantics is necessary because it seems like this can be done in a single hypercall if the caller only needs to know the total free memory.
