As for 4.14 and 4.19, I reviewed those patches and checked to code
generation for Spectre-v1.1. So for all the patches:

Reviewed-by: Julien Thierry <julien.thierry@....com>

However, 4.9 stable does not boot on TC2 (the arm32 big.Little platform
I have at hand), even without this backport (so at least it isn't these
patches breaking things). So I've been unable to test the Spectre-v2
big.Little patches.

Thanks,
