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)
