Someone please test this with tcrypt mode=200 with and without
the patch.

If there is a significant degradation I suggest that we back out
the FPU changes. Making your competitor's processor go slow is
not a nice thing to do, especially when you've just released a
processor in the same space.

If the degradation is small then I'll push it to Linus.

Thanks,
