Merge tag 'for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI changes from Bjorn Helgaas:
"Host bridge hotplug:
- Add MMCONFIG support for hot-added host bridges (Jiang Liu)
Device hotplug:
- Move fixups from __init to __devinit (Sebastian Andrzej Siewior)
- Call FINAL fixups for hot-added devices, too (Myron Stowe)
- Factor out generic code for P2P bridge hot-add (Yinghai Lu)
- Remove all functions in a slot, not just those with _EJx (Amos
Kong)
Dynamic resource management:
- Track bus number allocation (struct resource tree per domain)
(Yinghai Lu)
- Make P2P bridge 1K I/O windows work with resource reassignment
(Bjorn Helgaas, Yinghai Lu)
- Disable decoding while updating 64-bit BARs (Bjorn Helgaas)
Power management:
- Add PCIe runtime D3cold support (Huang Ying)
Virtualization:
- Add VFIO infrastructure (ACS, DMA source ID quirks) (Alex
Williamson)
- Add quirks for devices with broken INTx masking (Jan Kiszka)
Miscellaneous:
- Fix some PCI Express capability version issues (Myron Stowe)
- Factor out some arch code with a weak, generic, pcibios_setup()
(Myron Stowe)"
