    Subject[patch 1/5] x86: reduce minimum fake node size to 32M
    This patch changes the minimum fake node size from 64MB to 32MB so it is
    possible to test NUMA code at a greater scale on smaller machines
    (64 nodes on a 2G machine, 1024 nodes on 32G machine with
    CONFIG_NODES_SHIFT=10).
