For Spectre-v1.1 I also checked we do get the expected code sequence in the generated image at the expected locations. So, for patches 1 to 10: Reviewed-by: Julien Thierry <julien.thierry@arm.com> For Spectre-v2 big.Little patches, I managed to test this on TC2 and can confirm CPUs pick up the correct mitigation method. So, for patches 11 to 17: Reviewed-by: Julien Thierry <julien.thierry@arm.com> Tested-by: Julien Thierry <julien.thierry@arm.com> Thanks, -- Julien Thierry

From: "David A. Long" <dave.long@linaro.org> V4.19 backport of spectre patches from Russell M. King's spectre branch. Patches have been kvm-unit-test'ed on an arndale, run through kernelci, and handed off to ARM for functional testing.
