Hi.

It looks to me like the above commit from Andi causes a compilation failure on 
x86_64, because it makes pci_mmcfg_init non static:

arch/x86_64/pci/mmconfig.c:152: error: conflicting types for ‘pci_mmcfg_init’
arch/i386/pci/pci.h:85: error: previous declaration of ‘pci_mmcfg_init’ was 
here
make[1]: *** [arch/x86_64/pci/mmconfig.o] Error 1
make: *** [arch/x86_64/pci] Error 2

Regards,

Nigel
