These patches have been baking in linux-next for a whole development cycle. I waited for the release of -rc1 to run a final build-test on top of it before sending this pull request. Fortunatelly, after building 358 kernels overnight (basically all supported archs with a wide variety of configs), no more warnings have surfaced! :) Thus, we are in a good position to enable this compiler option for all versions of GCC that support it, with the exception of GCC-11, which appears to have some issues with this option[1].
