Somebody inverted the logic when and if the 'online' attribute for cpu devices appear. See 72486f1f8f0a2bc828b9d30cf4690cf2dd6807fc. The fix for s390 is this: 6721f77810dfcb7cbf8e97be6fa43fe2740dd0aa. Looks like arch/ppc was left out as well. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
