Hmm.. I somehow remember that one of them was 4 qwords while
the other was 8? Yet now, in the final driver source code on
the smmuv3_newapi branch, they are both 8 qwords? Feels like
some of the statement and the change doesn't match with the
reality so well -- hopefully I am not missing something...

Thanks
Nicolin
