Merge tag 'pci-v4.0-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI fixes from Bjorn Helgaas:
 "Here are some fixes for v4.0.  I apologize for how late they are.  We
  were hoping for some better fixes, but couldn't get them polished in
  time.  These fix:

   - a Xen domU oops with PCI passthrough devices
   - a sparc T5 boot failure
   - a STM SPEAr13xx crash (use after initdata freed)
   - a cpcihp hotplug driver thinko
   - an AER thinko that printed stack junk

  Details:

  Enumeration
    - Don't look for ACPI hotplug parameters if ACPI is disabled (Bjorn Helgaas)

  Resource management
    - Revert "sparc/PCI: Clip bridge windows to fit in upstream windows" (Bjorn Helgaas)

  AER
    - Avoid info leak in __print_tlp_header() (Rasmus Villemoes)

  PCI device hotplug
    - Add missing curly braces in cpci_configure_slot() (Dan Carpenter)

  ST Microelectronics SPEAr13xx host bridge driver
    - Drop __initdata from spear13xx_pcie_driver (Matwey V. Kornilov)
