  (Bjorn Helgaas)
- Remove the Battlemage-specific language from commit log and Document that this implementation
  does not track and aggregate requests from all child devices `below the Downstream Port.
  (Bjorn Helgaas)
- Add Rev 3.3 along with Section in commit log.
- Address cosmetic review comment.
- Added a notifier block.

Xe Pacthes:
- %s/VRAM_/VRAM_SR/
  (Rodrigo)
- %s/d3cold.allowed/d3cold.target_state
  (Rodrigo)
- Add has_vrsr flag and refactor pci_acpi_aux_power_setup.
