CET isn't a *problem* for retpoline. We've had a CET-compatible version
for a while now, and I posted it earlier. It's just that Andi was
working from an older version of my patches.

Of course, there's a school of thought that says that Intel should
postpone *everything* until this is all fixed sanely, but there's
nothing special about CET in that respect.
