At least the s390 version of smp_call_function() mask used to not return unless all IPIs where received on the target cpus. Your patch changes that. It will already return as soon as all IPIs have been sent. Unfortunately Martin's etr code in arch/s390/kernel/time.c relies on exactly the old semantics. Since this seems to be an s390 only issue, could you just drop the s390 conversion patch? We'll have to think about how to change the err code and convert later I guess. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
