     Wysocki)
   - Fix fallback to PCI_D0 (Rafael Wysocki)

  Miscellaneous
   - Factor quirk_io_region (Yinghai Lu)
   - Cache MSI capability offsets & cleanup (Gavin Shan, Bjorn Helgaas)
   - Clean up EISA resource initialization and logging (Bjorn Helgaas)
   - Fix prototype warnings (Andy Shevchenko, Bjorn Helgaas)
   - MIPS: Initialize of_node before scanning bus (Gabor Juhos)
   - Fix pcibios_get_phb_of_node() declaration "weak" annotation (Gabor
     Juhos)
   - Add MSI INTX_DISABLE quirks for AR8161/AR8162/etc (Xiong Huang)
   - Fix aer_inject return values (Prarit Bhargava)
   - Remove PME/ACPI dependency (Andrew Murray)
   - Use shared PCI_BUS_NUM() and PCI_DEVID() (Shuah Khan)"
