This one somehow slipped through the cracks... :-\

Ok, let's see: this could be relevant for the case when a module built
with a compiler which doesn't support retpolines, gets loaded on a
system which is built with retpolines.

Which is pretty seldom as the majority of setups out there should have
a retpoline-enabled compiler. And should not allow loading external
modules anyway, but that's a different story.

So, this close to the merge window, I'm inclined to delay this one after
it and have it take the x86/urgent fixes path. Unless someone screams
and says that patch breaks his system. I haven't seen any reports about
it so far so...

Thx.
