I didn't see any TME or MKTME-specific stuff in these patches.  Are you
assuming that all systems with any MEMBLOCK_CRYPTO_CAPABLE regions have
TME activated?

This also doesn't mention how userspace plans to *use* this information.
 I think you mentioned it before, but it needs to be in the cover letter
and changelogs too.
