Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI fixes from Bjorn Helgaas:
"Here are two patches from Rafael Wysocki.
One fixes an EHCI-related hibernation crash on ASUS boxes. We fixed a
similar suspend issue in v3.6-rc1, and this applies the same fix to
the hibernate path.
The other fixes D3/D3cold/D4 messages related to the D3cold support we
merged in v3.6-rc1."
(Removed redundant top non-fast-forward merge commit from pulled branch)
