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.
