The main ideas are: - Clean up the x86 PCI bus scanning interfaces. We had: struct pci_bus *pci_scan_bus_on_node(int bus, struct pci_ops *, int node) struct pci_bus *pcibios_scan_root(int bus) struct pci_bus *pci_scan_bus_with_sysdata(int bus) void pcibios_scan_specific_bus(int bus) These were all basically the same, so I kept only pcibios_scan_root(). - Get rid of mp_bus_to_node[]. This was basically a way of passing node info from the AMD "native host bridg driver" (amd_bus.c) into the PCI core. It was clunky and inconsistent between x86-64 and i386. I replaced it with x86_pci_root_bus_node(), analogous to the existing x86_pci_root_bus_resources(). - Remove _PXM knowledge from the PCI host bridge, IOMMU, and APIC code. They really only care about the NUMA node number, not the raw _PXM value. --- Bjorn Helgaas (17): x86/PCI: Drop pcibios_scan_root() check for bus already scanned x86/PCI: Use pcibios_scan_root() instead of pci_scan_bus_with_sysdata() x86/PCI: Use pcibios_scan_root() instead of pci_scan_bus_on_node() x86/PCI: Merge pci_scan_bus_on_node() into pcibios_scan_root() x86/PCI: Drop return value of pcibios_scan_root() x86/PCI: Add x86_pci_root_bus_node() to look up NUMA node from PCI bus x86/PCI: Use x86_pci_root_bus_node() instead of get_mp_bus_to_node() x86/PCI: Remove mp_bus_to_node[], set_mp_bus_to_node(), get_mp_bus_to_node() x86/PCI: Remove unnecessary list_empty(&pci_root_infos) check x86/PCI: Use NUMA_NO_NODE, not -1, for unknown node x86/PCI: Remove acpi_get_pxm() usage ia64 / sba_iommu: Use NUMA_NO_NODE, not MAX_NUMNODES, for unknown node ia64: Remove acpi_get_pxm() usage ACPI / numa: Fix acpi_get_node() prototype ACPI / numa: Simplify acpi_get_node() style ACPI / numa: Make __acpi_map_pxm_to_node(), acpi_get_pxm() static ACPI / numa: Use __weak, not the gcc-specific version arch/ia64/hp/common/sba_iommu.c | 32 +++------- arch/ia64/include/asm/pci.h | 2 - arch/ia64/kernel/acpi.c | 28 ++------- arch/ia64/pci/pci.c | 10 +-- arch/x86/include/asm/pci.h | 7 -- arch/x86/include/asm/topology.h | 14 ---- arch/x86/pci/acpi.c | 29 ++------- arch/x86/pci/amd_bus.c | 10 --- arch/x86/pci/bus_numa.c | 13 +++- arch/x86/pci/common.c | 128 +++++---------------------------------- arch/x86/pci/fixup.c | 6 +- arch/x86/pci/irq.c | 6 -- arch/x86/pci/legacy.c | 4 - arch/x86/pci/numaq_32.c | 6 +- arch/x86/pci/visws.c | 4 + drivers/acpi/numa.c | 16 ++--- include/acpi/acpi_numa.h | 1 include/linux/acpi.h | 9 +-- 18 files changed, 75 insertions(+), 250 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
