Unfortunately make oldconfig doesn't show a lot more information for each option, such as the context, so it is sometimes difficult to give the right answer. In this case the best way to go is to remember the option name and revise it afterwards through one of the graphical kernel configuration tools. For listing new options and doing research about them, make listnewconfig can be used before running make oldconfig.
