    No, it's also used by ps to resolve WCHAN in "ps -xl".

    The situation is awkward if you have the wrong version of System.map
    in /boot and you run "ps -xl". It will resolve the WCHAN numbers to
    names, but the names will be wrong. Very confusing. I agitated to
    include a step about copying System.map to the right place in the
    kernel install documentation / scripts, but I don't think it happened.
