From: Heiko Carstens <heiko.carstens@xxxxxxxxxx> When converting a 64 bit psw to a 128 bit psw the addressing mode bit of the "addr" part of the 64 bit psw must be moved to the basic addressing mode bit of the "mask" part of the 128 bit psw. In addition the addressing mode bit must be cleared when moved to the "addr" part of the 128 bit psw. Otherwise an invalid psw would be generated if the orginal psw was in the 31 bit addressing mode.
