I'm not cool with even discussing this on the super-sekrit list.
I don't see the point of keeping this secret, and we had much too many
issues *because* L1TF was secret.
So I'm done with this list, until we have some actual new embargo patches.
I'm also not sure the above makes sense. The kernel mapping is always
available. I do not see how you are going to do it, but if there are
patches to discuss it, they shouldn't be discussed on the speck list.
