From 192b2e742c06af399e8eecb4a1726520bfccece8 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 26 Feb 2018 13:17:07 +1100 Subject: [PATCH] selftests/powerpc: Skip tm-trap if transactional memory is not enabled Some processor revisions do not support transactional memory, and additionally kernel support can be disabled. In either case the tm-trap test should be skipped, otherwise it will fail with a SIGILL.
