The following tinny patch fixes a little ommission from the implementation
of the sys_query_module function. As a nice sideeffect it will make the
live for some cracers little harder :-)

The patch is against an vanilla linux-2.1.56 kernel. Please apply it to
the next kernel revision.

Many thank's in advance!
