#     selftests/powerpc: Use proper error code to check fault address
#     
#     ERR_NX_TRANSLATION(CSB.CC=5) is for internal to VAS for fault handling
#     and should not used by OS. ERR_NX_AT_FAULT(CSB.CC=250) is the proper
#     error code should be reported by OS when NX encounters address
#     translation failure.
#     
#     This patch uses CC=250 to determine the fault address when the request
#     is not successful.
