2.1.41 <not SMP>

A kernel crash, "Unable to handle NULL Pointer dereference at 000000"...
will be caused by::

# od -x /dev/kmem

I used to be able to __READ__ page zero. I think you can't do that anymore.
If so, /dev/kmem should not access the restricted page. Users can crash
the machine with simple commands.

Cheers,
Dick
