According to the PoP:

"When the enhanced-DAT facility 1 is not installed, or
   when the facility is installed but the multiple-block
   control is zero, general register R 2 contains a real
   address. When the enhanced-DAT facility 1 is
   installed and the multiple-block control is one, gen-
   eral register R 2 contains an absolute address."

Don't we have to take that into consideration here, too?

We don't support EDAT1 a.k.a. huge pages yet. If we ever do, we have to further extend this code.

Thanks!
