I am not a big fan of that patch either, but i cant think of a cleaner
way to do it. 
The violation already happens with the LLTX flag. So maybe a big warning
that says "Do this only if you driver is LLTX enabled". The other way to
do it is put a check to see if LLTX is enabled before releasing that
lock - but why the extra cycles? Driver writer should know.
