If you're going to set/clear the X86_FEATURE_RETPOLINE and
X86_FEATURE_RETPOLINE_AMD features (sorry, there are two of them now.
Blame Linus), you probably want to base on the retpoline branch
instead? It was Arjan's choice to put retpoline first, wasn't it?

In the last few days we've gone from a coherent patch series which was
far from perfect but which was at least basically complete and
functional, to disparate patch series all of which conflict. And some
of which haven't even been posted publicly yet at all (IBPB, and I
still haven't actually seen the variant 1 patches in public).

It would be really good to pull everything together, even if it's going
to receive significant bikeshedding.
