For example, with layout below Node 0 address: 0000 xxxx 0000 xxxx Node 1 address: xxxx 1111 xxxx 1111 Note: - Memory from low to high - 0/1: Node id - x: Invalid memory of a node When mm probes the memory map, without CONFIG_NODES_SPAN_OTHER_NODES config, mm only checks the memory validity but not the node id. Because of that, Node 1 also detects the memory from node 0 as below when it scans from the start address to the end address of node 1. Node 0 address: 0000 xxxx xxxx xxxx Node 1 address: xxxx 1111 1111 1111 This layout could occur on any architecture. Most of them enables this config by default with CONFIG_NUMA. This patch, by default, enables CONFIG_NODES_SPAN_OTHER_NODES or uses early_pfn_in_nid() for NUMA.
