bind mempolicies only support one zone, always the highest. This means on numaq
only highmem is policied.
DMA/DMA32 is not policied for obvious reasons (they often don't exist on
all nodes)

Why? That would just complicate everything. In particular it would mean
you would need multiple fallback lists per VMA, which would increase
the memory usage significantly.
