    What about:

    /*
     * This mechanism uses a legacy BIOS call to detect PCI configuration, but
     * such calls are not available on systems with UEFI firmware.  For UEFI
     * systems we must assume some reasonable defaults and scan all possible buses.
     */
    
    1. Yes, thats much better indeed. So I did copy it;)

  1. I think this makes sense. I guess in the future, we can actually get this out of ACPI if we want, so we don't have to search everything or at least maybe use it to supplement things (which is what xpv was going to do some day...).
