How about renumbering the nodes? Node 0 is the one with no DMA memory and node 1 may be the one with the DMA? That would take care of things even without core modifications. We can start on node 0 (which hardware 1) and consume the required memory for boot there not impacting the node with the DMA memory. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
