CONFIG_DEBUG_KERNEL, like CONFIG_EXPERT, should not directly affect the code included in the kernel; it should just avoid asking about a pile of other debugging options. In practice, a small amount of architecture-specific code (for powerpc, parisc, and blackfin) did use it as a generic debug option, but that needs fixing. So, for now, turn on CONFIG_EXPERT and live with having CONFIG_DEBUG_KERNEL turned on. That aside, several of the above options should not depend on EXPERT; why would PCSPKR_PLATFORM or DEBUG_MEMORY_INIT need to depend on EXPERT? - Josh Triplett -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
