I don't think that the other patches should be really applied to upstream (they could be very handy for debugging this horrible issue, once we could do any debugging of it, thoug), as they don't protect against anyone creating a new rw mapping, which can then be freely used to still overwrite the mmio area without any problems. -- Jiri Kosina SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
