/*
* IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',
* 0 otherwise. Note that CONFIG_FOO=y results in "#define CONFIG_FOO 1" in

#define IS_ENABLED(option) __or(IS_BUILTIN(option), IS_MODULE(option))
It cleanly handles the module case, which i guess most people would
get wrong.
