Hello Randy, I confused it. CR4_FEATURES_ADDR was in the glue code of parallels binary only modules, but it sounded like a a MMU definition. Thanks a lot. That was why my pickaxe did not work out in the first place. However I have a workaround for the damn build problem. See http://wwwcip.informatik.uni-erlangen.de/~sithglan/parallels/ Thanks, Thomas - : send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
