This breaks several PPC SMP systems in which only a single processor is allowed to be selected as the destination of the IRQ. What is the right answer in fixing this? Should we: cpumask_t irq_default_affinity = 1; instead of cpumask_t irq_default_affinity = CPU_MASK_ALL? - k -- 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/
