Yes, that makes sense.


I think it would be easier to remove the config option entirely on s390
and just always warn. As I said earlier in this thread, I generally
don't think this particular warning is more important than a lot of
the other ones that we don't turn into errors.

I do think it would be helpful to optionally build parts of the kernel
with the much stronger '-Werror', which we already do for some
architectures. You could do that with inverted logic (bool "Disable -Werror
compile option) and fix all warnings in allnoconfig to make all of
allnoconfig, allyesconfig and defconfig build.
