If I understand correctly, without MMU... there is per task unique address space, thus it's up to you to define the boundary, correct? regards, Mulyadi. - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
