As far as I can tell, the apply_returns() fix isn't necessarily urgent,
since after commit 095b8303f383 it went from being an actual bug to just
dead code: the optimization will never take effect now that none of the
rethunk cases use __x86_return_thunk.

On the other hand, if I'm too late sending this, it should be harmless
to merge it into the final v6.5 release.

For the rest of the patches, I think the merge window is fine.

Thanks!
