From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Make it possible to answer "m or y" or "y or m" to
oldconfig so that scripted kernel builds can easily
enable new features not present in the existing .config.
The particular use case I have in mind is continuous integration
where you probably want to test build any new features. Currently
you would have to either blindly try both 'y' and 'm' answers
or parse the output to know which one will be accepted.
