All of the clang commits have been backported to 4.4. It would be nice
to have these commits because that warning is very noisy.

Note, this will not apply cleanly to 4.4, 4.9, and 4.14. I have attached
mbox files with the conflicts resolved, after build testing for arm64
and x86_64. 4.19 is a clean cherry pick for me.

Also added Masahiro to CC.

Cheers,
Nathan
