Especially the -e s/x86_64/x86. It causes UML to get build for x86 which is a nasty change of the default behavior. Before your change you got a UML kernel for the underlying arch just by running "make linux ARCH=um". Now it will always build a x86 UML kernel, also if you run it on x86_64 and one is forced to override SUBARCH by hand. -- Thanks, //richard -- 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/
