Current pages NUMA-interleaving policy is 1:1 mapping, 1 for CPU node, 1 for remote note. As more types of tiered memory systems having CPU-less memory nodes are coming, this patchset introduces an N:M interleave policy, which N pages are allocated from the top-tier node while M pages are allocated from low-tier nodes.
