I would have loved to have all three show up in the same stable
releases, and for some kernels (5.10 and newer) that looks like it will
happen. I was not happy with the 5.4 and older backports just yet
enough to be able to add them to a -rc.

Hopefully James and I can work through the issues and have them in a
kernel soon.

Note, Linus's tree, and these backports, all do break when using clang
for arm32 and arm64, so that is an issue for many ARM users. Hopefully
that can be resolved and when the fixes hit Linus's tree, I'll be glad
to take them to stable releases.

thanks,
