This will hide some ugly implementation details. In addition, change the pci_create_bus() interface to pass in available resources to get them settled down early. This is to avoid possible resource conflicts while doing pci_scan_slot() in pci_scan_child_bus(). Note that pcibios_fixup_bus() can get rid of such conflicts, but it's done AFTER scanning slots. Deng-Cheng Zhu (3): MIPS: PCI: Use pci_bus_remove_resources()/pci_bus_add_resource() to set up root resources PCI: Pass available resources into pci_create_bus() MIPS: PCI: Pass controller's resources to pci_create_bus() in pcibios_scanbus() arch/microblaze/pci/pci-common.c | 3 +- arch/mips/pci/pci.c | 49 +++++++++++++++++++++++++++++++++++-- arch/powerpc/kernel/pci-common.c | 3 +- arch/sparc/kernel/pci.c | 3 +- arch/x86/pci/acpi.c | 2 +- drivers/pci/probe.c | 15 ++++++++--- include/linux/pci.h | 3 +- 7 files changed, 66 insertions(+), 12 deletions(-)
