Applied in place of earlier patch.
The basic MMCONFIG messages look better:
$ dmesg | grep MMCONFIG
[ 12.985055] PCI: MMCONFIG for domain 0000 [bus 00-ff] at [mem 0x80000000-0x8fffffff] (base 0x80000000)
[ 13.078050] PCI: not using MMCONFIG
[ 13.666053] PCI: MMCONFIG for domain 0000 [bus 00-ff] at [mem 0x80000000-0x8fffffff] (base 0x80000000)
[ 13.795049] PCI: MMCONFIG at [mem 0x80000000-0x8fffffff] reserved in ACPI motherboard resources or EFI
Full dmesg attached.
