  PCI PM: Introduce __pci_[start|complete]_power_transition() (rev. 2)
  PCI PM: Restore config spaces of all devices during early resume
  PCI PM: Make pci_set_power_state() handle devices with no PM support
  PCI PM: Put devices into low power states during late suspend (rev. 2)
  PCI PM: Move pci_restore_standard_config to pci-driver.c
  PCI PM: Use pci_set_power_state during early resume
  PCI PM: Consistently use variable name "error" for pm call return values
  kexec: Change kexec jump code ordering
