    I wish the actual warning was worded that way. :P

    What distro are you using? Does it have a package for a newer
    compiler? I'm honestly curious about what policies if any the kernel
    has for supporting developer's toolchains from their distributions.
    (ie. Arnd usually has pretty good stats what distro's use which
    version of GCC and are still supported; Do we strive to not break
    them? Is asking kernel devs to compile their own toolchain too much to
    ask? Is it still if they're using really old distro's/toolchains that
    we don't want to support? Do we survey kernel devs about what they're
    using?). Apologies if this is already documented somewhere, but if
    not I'd eventually like to brainstorm and write it down somewhere in
    the tree. Documentation/process/changes.rst doesn't really answer the
    above questions, I think.
