Yes, most of the logic was borrowed from mmconfig_64.c file, 
mmconfig_32.c looks differently, though. It is not simple to merge them 
both. IMO, we have two choices:
1. Refactor and move mmconfig_64.c out of x86 to e.g. drivers/acpi/ and 
let it be default.
2. Stay with solution presented in this patch.
3. Thoughts ?
