    Pull PCI updates from Bjorn Helgaas:
     "The interesting things here are:
    
       - Turn on Config Request Retry Status Software Visibility.  This
         caused hangs last time, but we included a fix this time.
       - Rework PCI device configuration to use _HPP/_HPX more aggressively
       - Allow PCI devices to be put into D3cold during system suspend
