The PCI Write Barrier instruction ignores the registers encoded in it. There is thus no need to explicitly set the register to zero or to associate it with a variable at all. In the resulting binary this removes an unnecessary lghi and it makes the code simpler. Signed-off-by: Niklas Schnelle <schnelle@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
