My patch doesn't make any difference here. Also it doesn't make any sense to print such static and identical information for each and every cpu line. The purpose of the extended and parsable output is to give the user an overview of the cpu topology and per cpu attributes. It's purpose is certainly not to give an overview of the whole system. -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
