From: Christoph Lameter get_pfn_range_for_nid() is called multiple times for each node at boot time. Each time, it will warn about nodes with no memory, resulting in boot messages like: Node 0 active with no memory Node 0 active with no memory Node 0 active with no memory Node 0 active with no memory Node 0 active with no memory Node 0 active with no memory On node 0 totalpages: 0 Node 0 active with no memory Node 0 active with no memory DMA zone: 0 pages used for memmap Node 0 active with no memory Node 0 active with no memory Normal zone: 0 pages used for memmap Node 0 active with no memory Node 0 active with no memory Movable zone: 0 pages used for memmap and so on for each memoryless node. We already have the "On node N totalpages: ..." and other related messages, so drop the "Node N active with no memory" warnings.
