The problem is that in the previous code, input_mode could never be set
to 'ask_new' ('oldconfig' in the new code), both oldconfig and
silentoldconfig set the variable to 'ask_silent'. Therefore, the 'case
ask_new:' label had no effect here. The fix is correct, both oldconfig
and silentoldconfig jump to the same place again.
Linus, will you apply this directly or should I apply it to the kbuild
tree and send you a pull request?
