I would encourage anyone who has been impacted by this to communicate
that back to the folks at Intel from whom they received the out-of-tree
code about the impact.

Heck if I know.  I don't think LKML is a great place to discuss Intel
licensing requirements.

What I *do* know is that when builds a platform without Flexible Launch
Control, Linux does not support SGX on that platform.  I guess that
could be spelled out in some documentation explicitly, if it isn't already.
