Then my patch get_mp_bus_to_node_as_early will use that sysdata as node as early as possible before the pci_scan bus is called. then Mul came out his patch ...to split the sharing that will never happen. But andi picked muli patch even my patch stay a while in -mm. Also i don't think anyone test muli sysdata patch with amd64 platform with acpi=off. even muli himself. calgary support bus numa at this time? i mean mult peer root bus on different node.. anyway I will produce my patch in v3...
