    Subject[PATCH -v5 0/24] PCI: allocate pci bus num range for unassigned bridge busn + pci rescan cleanup
    Date
    cdef5a1: PCI: clean up rescan_bus_bridge_resize
    7b6deb4: PCI: make pci_rescan_bus_bridge_resize use pci_scan_bridge instead
    876bd4a: PCI: Add pci_bus_add_single_device()
    6e5f346: PCI, sysfs: create rescan_bridge under /sys/.../pci/devices/... for pci bridges
    3c92113: PCI, sys: Use device_type and attr_groups with pci dev
    e6d3c54: PCI, pciehp: Remove not needed bus number range checking
    2306e31: PCI: Double checking setting for bus register and bus struct.
    daddc90: pcmcia: remove workaround for fixing pci parent bus subordinate
    6a88939: PCI: Seperate child bus scanning to two passes overall
    60c7d94: PCI: kill pci_fixup_parent_subordinate_busnr()
    e9e72be: PCI: Allocate bus range instead of use max blindly
    f22af7f: PCI: Strict checking of valid range for bridge
    8656ea6: PCI: Probe safe range that we can use for unassigned bridge.
    4023fc3: PCI: Add pci_bus_extend/shrink_top()
    a066c95: PCI, parisc: Register busn_res for root buses
    d069fbb: PCI, powerpc: Register busn_res for root buses
    f00e514: PCI, ia64: Register busn_res for root buses
    1a203f1: PCI, x86: Register busn_res for root buses
    8b1b01b: PCI: Add busn_res tracking in core
    a9ccca7: PCI: add /proc/iobusn
    ec1cdb3: PCI: Add busn_res operation functions
    2a09fbd: Make %pR could handle bus resource with domain
    9c83a59: PCI: add busn inline helper
    b18cd6a: PCI: Add iobusn_resource

    Set up iobusn_resource tree, and register bus number range to it.
    Later when need to find bus range, will try to allocate from the tree

    Need to test on arches other than x86. esp for ia64 and powerpc that support
    more than on peer root buses.

    last five patches are rescan cleanup that make use busn alloc.

    could be found at:
    git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-busn-alloc

    -v2: according to Jesse, split to more small patches.
    -v3: address some request from Bjorn. like make use %pR for busn_res debug print
    out, and move the comment change with code change.
    -v4: fixes the problem about rescan that Bjorn found.
    -v5: add /proc/iobusn that is requested by Bjorn.
    remove old workaround from pciehp.
    add rescan_bridge for pci bridge in /sys

    Thanks

    Yinghai
