Feel free to cc the appropriate list. Regarding this change, as I understand it, when CONFIG_EXPOLINE_EXTERN=y out-of-tree kernel modules will need to link against arch/s390x/lib/expoline.o, right? And if so, shouldn't the top level 'prepare_modules' target create expoline.o for this purpose? Regards, -- Joe
