I think the complaints are more about how it works that the intent. Kernel engineers are by their very nature very risk averse, so it would indeed be good to set the bit correctly in the cpu capability flags, and to do that based on the machine type. I might just have a machine which exhibits this behaviour, I will try and look it out and see if we can morph this into something appropriate. -apw -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
