So we have to get that label address with got. And when boot a relocated kernel, we should reset ipvr properly again after .relocate. Signed-off-by: Tiejun Chen <[email protected]> ---

Yes, I think I can simplify this as you pointed :) Thanks, Tiejun -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
