Pull PCI update from Bjorn Helgaas:
"Host bridge hotplug:
- Untangle _PRT from struct pci_bus (Bjorn Helgaas)
- Request _OSC control before scanning root bus (Taku Izumi)
- Assign resources when adding host bridge (Yinghai Lu)
- Remove root bus when removing host bridge (Yinghai Lu)
- Remove _PRT during hot remove (Yinghai Lu)
SRIOV
- Add sysfs knobs to control numVFs (Don Dutile)
Power management
- Notify devices when power resource turned on (Huang Ying)
Bug fixes
- Work around broken _SEG on HP xw9300 (Bjorn Helgaas)
- Keep runtime PM enabled for unbound PCI devices (Huang Ying)
- Fix Optimus dual-GPU runtime D3 suspend issue (Dave Airlie)
- Fix xen frontend shutdown issue (David Vrabel)
- Work around PLX PCI 9050 BAR alignment erratum (Ian Abbott)
Miscellaneous
- Add GPL license for drivers/pci/ioapic (Andrew Cooks)
- Add standard PCI-X, PCIe ASPM register #defines (Bjorn Helgaas)
- NumaChip remote PCI support (Daniel Blueman)
- Fix PCIe Link Capabilities Supported Link Speed definition (Jingoo
Han)
- Convert dev_printk() to dev_info(), etc (Joe Perches)
- Add support for non PCI BAR ROM data (Matthew Garrett)
- Add x86 support for host bridge translation offset (Mike Yoknis)
- Report success only when every driver supports AER (Vijay
Pandarathil)"
Fix up trivial conflicts.
