- Skip enabling ExtTag on VFs since that bit is Reserved and causes
  misleading log messages (Håkon Bugge)

- Mark 3ware-9650SA Root Port Extended Tags as broken since 9650SA can't
  handle 8-bit tags (Jörg Wedekind)

- Release domain number from the correct IDA when a PCI host bridge has no
  parent device (Sergey Shtylyov)

- Initialize endpoint Read Completion Boundary to match Root Port,
  regardless of ACPI _HPX (Håkon Bugge)

- Apply _HPX PCIe Setting Record only to AER configuration, and only when
  OS owns PCIe hotplug but not AER, to avoid clobbering Extended Tag and
  Relaxed Ordering settings (Håkon Bugge)

- Clear PCIe Root Status register with a write, not a read/modify/write
  (Lukas Wunner)

* pci/enumeration:
  PCI/PME: Replace RMW of Root Status register with direct write
  PCI/ACPI: Restrict program_hpx_type2() to AER bits
  PCI: Initialize RCB from pci_configure_device()
  PCI: Check parent for NULL in of_pci_bus_release_domain_nr()
  PCI: Mark 3ware-9650SA Root Port Extended Tags as broken
  PCI: Do not attempt to set ExtTag for VFs
