So far what I have found, is that to be bullet proof you should use
make mrproper (which does more than make clean) and then rebuild
your desired config file again. But that you can skip make clean
(and make mrproper) in most cases.
Yes. I normally don't do either make clean or make mrproper during a
bisect. Perhaps if I'm crossing a major revision boundary (e.g. the
bisect takes me from v3.18 to v3.17-rc4) I'll do a make clean, but
otherwise I avoid it. I've never done an mrproper as it seems too easy
to make a mistake while doing the reconfig. I just let Kconfig ask me
the relevant questions during each build.
