    even reading from certaing ioremap'd areas is dangerous. (ok current
    /proc/kcore prevents that from happening by skipping such).

    speaking of /dev/kmem, I always wondered why Alan Cox (or someone
    else?) objected to adding vwrite() ability to write to vmalloc'd addresses
    via /dev/kmem and this discussion is as good as any to ask here :)

    I.e. it is kind of assymetric to allow reading (via vread()) and disallow
    writing. I have a patch (by Amit Kale) that adds this support.
