Subject: [PATCH 5.3 059/166] selftests/powerpc: Retry on host facility unavailable

From: Gustavo Romero <gromero@...ux.vnet.ibm.com>

[ Upstream commit 6652bf6408895b09d31fd4128a1589a1a0672823 ]

TM test tm-unavailable must take into account aborts due to host aborting
a transactin because of a facility unavailable exception, just like it
already does for aborts on reschedules (TM_CAUSE_KVM_RESCHED).
