Bjorn Helgaas afcf21c2be x86/PCI: Add x86_pci_root_bus_node() to look up NUMA node from PCI bus ... The AMD early_fill_mp_bus_info() already allocates a struct pci_root_info for each PCI host bridge it finds, and that structure contains the NUMA node number. We don't need to keep the same information in the mp_bus_to_node[] table. This adds x86_pci_root_bus_node(), which returns the NUMA node number, or NUMA_NO_NODE if the node is unknown. Note that unlike get_mp_bus_to_node(), x86_pci_root_bus_node() only works for root buses. For example, if amd_bus.c finds a host bridge on node 1 to [bus 00-0f], get_mp_bus_to_node() returns 1 for any bus between 00 and 0f, but x86_pci_root_bus_node() returns 1 for bus 00 and NUMA_NO_NODE for buses 01-0f.
