I'm hitting problems with this several times a day.
I'm used to switching from 32-bit to 64-bit x86 kernels and now i have to via the extra 'make mrproper' and that's quite annoying as i already tell kbuild that i want a 64-bit config via:
make ARCH=x86_64 defconfig
Why the extra forced step?
Also, there's things that need even more steps: i often take a config that triggers a breakage on 32-bit and change it to 64-bit via 'make oldconfig' - to see whether the bug is bitness invariant. I have to do something like:
mv .config .config.tmp make mrproper mv .config.tmp .config make ARCH=x86_64 oldconfig
This doesnt look right at all.
