Your patch only allows the condition behind resources that have 64-bits of significance, but that is not what the document above says about when this situation is allowed. Please implement the check either exactly as stated in the errata document, or more loosely if that is not possible, rather than more strictly than allowed. Your overly strict and restrictive checks are what got us into this predicament in the first place. :-( -- 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
