    Convenience more than anything.

    It's to do with how the configs for Fedora/RHEL kernels are generated.
    Rather than have a dozen separate .config files, and have to add a new
    option to each of them, it's done in a 'templated' manner.

    We have for eg, a config-generic, and then various config-$arch files,
    which are munged together with a perl script to generate a final .config
    that our build system eats for each arch it builds.

    Having a list of all the new options together means that I can just cut-n-paste
    that block of text into config-generic, and then drop out the ones that
    should be per-arch.

    I've felt it's another of those 'of little practical use to anyone not building
    a Fedora/RHEL kernel' type patches that I've not bothered pushing it upstream.

    Dave
