We definitely have platforms where the physical memory on node 0 that we skipped to leave physical address space for PCI mem mapped devices gets tagged back at the very top of memory, after other nodes. E.g. A 2-node system with 8G on each might look like this: 0-2G RAM on node 0 2G-4G PCI map space 4G-8G RAM on node 0 8G-16GRAM on node 1 16G-18G RAM on node 0 Is this the situation that we are talking about? Or something different? -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
