MMCFG ACPI table has no arch dependencies so it can be used across all
architectures. Currently MMCONFIG related code resides in arch/x86 directories.
This patch set is goint to isolate non-architecure specific code and make
it accessible from drivers/pci/ directory.

Tomasz Nowicki (6):
  x86, acpi, pci: Reorder logic of pci_mmconfig_insert() function
  x86, acpi, pci: Move arch-agnostic MMCFG code out of arch/x86/
    directory
  x86, acpi, pci: Move PCI config space accessors.
  x86, acpi, pci: mmconfig_{32,64}.c code refactoring - remove code
    duplication.
  x86, acpi, pci: mmconfig_64.c becomes default implementation for arch
    agnostic low-level direct PCI config space accessors via MMCONFIG.
  pci, acpi: Share ACPI PCI config space accessors.
