I have no plan to backport this to older kernels. This is new HW that
didn't exist (or wasn't publicly available) when 4.4/4.9 were released,
so 4.12 is effectively the first kernel I intend to support this erratum on.

If you have an interest in running older kernels on this HW, you'll have
to do the backport yourself. Please make sure you Cc both Mark and
myself on the patches.

Thanks,
