It would be fine today, but it will be not enough in 2016 and we would like to
give GNU/Linux distributions some time to propagate this patch.
For Knights Corner which is already on the market we need 61.
For Knights Landing we need 72.
For future generation it is not yet public information.

Right, I forgot this time, I'll send another patch just tell me whether 128
is ok, or please select any other value greater or equal known minimum
that you think will be more appropriate.

Thanks,
Lukas
