To avoid having to look manually for used but undefined Kconfig variables, I've written a script which tries do this efficiently, in case all other attention fail. It accounts for _MODULE suffix and for UML_ prefixes to Kconfig variable, but otherwise looks for exact matches (i.e. \<CONFIG_; this is done to exclude macros like MMCONFIG_). Undefined Kconfig variables should be not be removed without care, but for instance arch/i386/boot/ uses a bunch of undefined Kconfig vars: $ scripts/checkunknowndefines.sh arch/i386/boot/ arch/i386/boot/video.h uses undefined symbol VIDEO_400_HACK arch/i386/boot/video-vga.c uses undefined symbol VIDEO_400_HACK arch/i386/boot/video.c uses undefined symbol VIDEO_RETAIN arch/i386/boot/video.h uses undefined symbol VIDEO_RETAIN arch/i386/boot/video.h uses undefined symbol VIDEO_SVGA arch/i386/boot/video.h uses undefined symbol VIDEO_VESA arch/i386/boot/video-vesa.c uses undefined symbol VIDEO_VESA It should also be mentioned in SubmittingPatches and SubmitChecklist.
