Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it to lib/Kconfig.debug so each arch doesn't have to define it. This obviously makes the option generic, but that's fine because the config is already used in generic code. It's not obvious to me that sysrq-P actually does anything caution by keeping the most inclusive wording.
