    Subject[PATCH] sysctl: Scream if someone uses sys_sysctl

    As far as I can tell we never use sys_sysctl so I never expect to see
    these messages. But if we do see these it means that there are user
    space applications that need to be fixed before we can safely
    remove sys_sysctl.

    Since this patch was trivial I just wipped up this incremental
    version. The code compiles is all I know.
