This all should be summarized in the documentation (high-level model and
corner cases).
I am not sure whether it is necessary to document L1TF explicitly, since it is
quite obvious that MKTME doesn't prevent that. IMHO if needed we only need to
mention MKTME doesn't prevent any sort of cache based attack, since data in
cache is in clear.

In fact SGX doesn't prevent this either..
Sorry, was a bit unclear. I meant the assumptions and goals.
