For twl4030, if we can make twl4030_irq_thread to run at higher priority than that of other irq thread, the PIH irq disable time can be decreased further since other irq thread waken up by twl4030_irq_thread can preempt the running of twl4030_irq_thread, and the PIH irq will be enabled until complete of twl4030_irq_thread. thanks, -- Lei Ming -- 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
