    Maybe the %p that end up in dmesg (via the kernel message buffer) should
    be converted to text in a form that allows the code that reads them to
    substitute alternate text for non-root users?

    Then the actual addresses will be available to root (who can probably
    get most by other means) but not to the casual observer.
