Haren Myneni 6068e1a442 powerpc/vas: Report proper error code for address translation failure ... P9 DD2 NX workbook (Table 4-36) says DMA controller uses CC=5 internally for translation fault handling. NX reserves CC=250 for OS to notify user space when NX encounters address translation failure on the request buffer. Not an issue in earlier releases as NX does not get faults on kernel addresses. This patch defines CSB_CC_FAULT_ADDRESS(250) and updates CSB.CC with this proper error code for user space. Fixes: c96c4436ab ("powerpc/vas: Update CSB and notify process for fault CRBs") Signed-off-by: Haren Myneni <haren@linux.ibm.com> [mpe: Added Fixes tag and fix typo in comment] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/019fd53e7538c6f8f332d175df74b1815ef5aa8c.camel@linux.ibm.com		2020-07-15 23:09:55 +10:00
