    Subject[Patch 1/4] x86: get pg_data_t's memory from other node
    If system can create movable node which all memory of the
    node is allocated as ZONE_MOVABLE, setup_node_data() cannot
    allocate memory for the node's pg_data_t.
    So when memblock_alloc_nid() fails, setup_node_data() retries
    memblock_alloc().
