Merge tag 'pci-v3.10-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI updates from Bjorn Helgaas:
"Here are some more fixes for v3.10. The Moorestown update broke Intel
Medfield devices, so I reverted it. The acpiphp change fixes a
regression: we broke hotplug notifications to host bridges when we
split acpiphp into the host-bridge related part and the
endpoint-related part.
Moorestown
Revert "x86/pci/mrst: Use configuration mechanism 1 for 00:00.0, 00:02.0, 00:03.0"
Hotplug
