This series stretches across several archs, so I would expect that it could've been addressed for some of them but would take more time than submitting this "point fix" now, targeting one obsolete config option.

I've personally hit it for arm64 on the first place, and looking further into the option itself I realized that it is missing from the kernel tree completely and decided to fix all archs affected at once.
