We need more specifics than this. It's an important factor for what,
exactly? Who will consume this and what will they do with it?

I'm also not sure we want to have an Intel product name in the ABI. If
we're meaning to tell folks if hardware memory encryption is available
on the platform, let's say _that_, rather than talk about MKTME.

Also, MKTME enabling isn't all that interesting. TME is much more
interesting and much more opaque.
