I was thinking if we made it a special resource type we'd have to change any platform drivers to use it; i.e. it wouldn't be IORESOURCE_MEM or IORESOURCE_IO but IORESOURCE_DRAGONS. That way it wouldn't be part of the normal resource space. But that's definitely overkill. I think Bjorn's fix is sufficient. -- Jesse Barnes, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
