Hello! The README file in the linux-3.13.0 source directory will tell you
that
"make oldconfig" Default all questions based on the contents of your existing
./.config file and asking about new config symbols.
You can read the descriptions of the new config symbols and decide for
yourself or just hit enter to get the default. If you'd rather get oldconfig
+ all defaults, you can instead use
"make olddefconfig" Like above, but sets new symbols to their default values
without prompting.
Since you're only changing one little bit, these could come handy
