    Subject[PATCH v3 00/11] PCI core learns hotplug
    Date
    This is v3 of the patch series that introduces function-level hotplug 
    to the PCI core. It is against Jesse's linux-next branch.

    I've been doing lots of testing, and found and fixed several small
    buglets, both in my code and elsewhere in PCI. In order to test this
    patchset, you will also need these patches:

    http://thread.gmane.org/gmane.linux.kernel.pci/3437
    http://lkml.org/lkml/2009/3/7/173

    There is still one major bug somewhere that shows up only when using
    the PCIe portdriver (that is, any time PCIe support is built into
    the kernel). You get an oops during multiple remove/rescan cycles,
    especially on devices with an internal bridge.

    This symptom does not appear on the exact same hardware topology, removing
    and rescanning the exact same device, when not using the PCIe port driver.

    I'm still not sure what's going on, so if anyone wants to play with
    this series, I'd truly appreciate any help.

    Thanks.

    v2 -> v3:
    - properly remove device with internal bridge
    - added Kenji Kaneshige's pci_is_root_bus() interface
    - dropped whitespace cleanups for another time

    v1 -> v2:
    - incorporated lots of Trent Piepho's work
    - beefed up pci_do_scan_bus as heavy lifter for rescanning
    - small bugfixes folded into earlier patches to get everything working

    PCI Hotplug: schedule fakephp for feature removal
    PCI Hotplug: rename legacy_fakephp to fakephp
    PCI: Introduce /sys/bus/pci/devices/.../rescan
    PCI: Introduce /sys/bus/pci/devices/.../remove
    PCI: Introduce /sys/bus/pci/rescan
    PCI: beef up pci_do_scan_bus()
    PCI: always scan child buses

    Kenji Kaneshige (1):
    PCI: pci_is_root_bus helper

    Trent Piepho (3):
    PCI Hotplug: restore fakephp interface with complete reimplementation
    PCI: pci_scan_slot() returns newly found devices
    PCI: don't scan existing devices
