Hi Greg, Actually our goal is to merge the 3 patches to 4.19.y and 4.14.y stable branch, however, I mistakenly believed that the patches should be present in 4.20.y first and did not notice that 4.20.y has been EOL. Sorry for that.

The 4.20.y stable branch is long end-of-life, so there is nothing to be able to apply any patch to, sorry. Remember to always check the front page of kernel.org for what trees are still active. greg k-h
