I'm one of those people who *really* wants to cut down the kernel size.

If it's 5k nobody will care. I care about 5K. (But honestly, I don't actively hunt stuff less than 10K in size, because there's too many of them to chase, currently). -- Tim -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
