The issue of commit d91525eb8ee6 ("ACPI, EINJ: Enhance error injection tolerance
level") on x86 is also happened on our own arm64 platform. We sent a patch[1]
trying to fix this issue in an arch-specific way as x86 does, but according to
the suggestion from Lorenzo and Catalin, we can consolidate the PCI MCFG part
then fix it in a more common way.

v2 change:
Fix the "undefined reference to `pci_mmcfg_list'" build error in case of
PCI_CONFIG=n, reported by the kernel test robot.

Xuesong Chen (2):
  PCI: MCFG: Consolidate the separate PCI MCFG table entry list
  ACPI: APEI: Filter the PCI MCFG address with an arch-agnostic method
