Subject: powerpc/pseries: Fix software invalidate TCE
From: Michael Neuling <[email protected]>
commit bc6dc752f35488160ffac07ae91bed1bddaea32a upstream.
The following added support for powernv but broke pseries/BML:
1f1616e powerpc/powernv: Add TCE SW invalidation support
TCE_PCI_SW_INVAL was split into FREE and CREATE flags but the tests in
the pseries code were not updated to reflect this.
