Merge branches 'pci/host-generic', 'pci/host-mvebu', 'pci/host-rcar', 'pci/host-tegra', 'pci/msi', 'pci/misc', 'pci/resource' and 'pci/virtualization' into next

* pci/host-generic:
  PCI: generic: Fix GPL v2 license string typo

* pci/host-mvebu:
  PCI: mvebu: Fix GPL v2 license string typo

* pci/host-rcar:
  PCI: rcar: Fix GPL v2 license string typo

* pci/host-tegra:
  PCI: tegra: Fix GPL v2 license string typo

* pci/msi:
  PCI/MSI: Use irq_get_msi_desc() to simplify code
  PCI/MSI: Remove unused list access in __pci_restore_msix_state()
  PCI/MSI: Retrieve first MSI IRQ from msi_desc rather than pci_dev
  PCI/MSI: Remove unused function msi_remove_pci_irq_vectors()
  PCI/MSI: Add msi_setup_entry() to clean up MSI initialization

* pci/misc:
  PCI: Configure ASPM when enabling device
  x86: don't exclude low BIOS area when allocating address space for non-PCI cards
  PCI: Add include guard to include/linux/pci_ids.h
  x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()

* pci/resource:
  PCI: Tidy resource assignment messages
  PCI: Return conventional error values from pci_revert_fw_address()
  PCI: Cleanup control flow
  PCI: Support BAR sizes up to 128GB
  PCI: Keep original resource if we fail to expand it

* pci/virtualization:
  powerpc/pci: Remove duplicate logic
  PCI: Make resetting secondary bus logic common
