  "message": "x86: get mp_bus_to_node early\n\nCurrently, on an amd k8 system with multi ht chains, the numa_node of\npci devices under /sys/devices/pci0000:80/* is always 0, even if that\nchain is on node 1 or 2 or 3.\n\nWorkaround: pcibus_to_node(bus) is used when we want to get the node that\npci_device is on.\n\nIn struct device, we already have numa_node member, and we could use\ndev_to_node()/set_dev_node() to get and set numa_node in the device.\nset_dev_node is called in pci_device_add() with pcibus_to_node(bus),\nand pcibus_to_node uses bus-\u003esysdata for nodeid.\n\nThe problem is when pci_add_device is called, bus-\u003esysdata is not assigned\ncorrect nodeid yet. The result is that numa_node will always be 0.\n\npcibios_scan_root and pci_scan_root could take sysdata. So we need to get\nmp_bus_to_node mapping before these two are called, and thus\nget_mp_bus_to_node could get correct node for sysdata in root bus.\n\nIn scanning of the root bus, all child busses will take parent bus sysdata.\nSo all pci_device-\u003edev.numa_node will be assigned correctly and automatically.\n\nLater we could use dev_to_node(\u0026pci_dev-\u003edev) to get numa_node, and we\ncould also could make other bus specific device get the correct numa_node\ntoo.\n\nThis is an updated version of pci_sysdata and Jeff\u0027s pci_domain patch.\n\n[ mingo@elte.hu: build fix ]\n\nSigned-off-by: Yinghai Lu \u003cyinghai.lu@sun.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n",
