I don't know exactly the reasons behind .config/defconfig both existing,
but I think that defconfig shouldn't be altered ever, and that .config
should be copied to defconfig at a late stage of "make vmlinux" (or some
other target that is done when building vmlinux). Oh well proberbly won't
happen, just my opinion.

"make clean" is sufficient, if the patch dosn't change the dependancies (ie
create new files/delete existing files), other wise a "make dep" is needed.
