Subject: [PATCH 4/4] x86/insn: perf tools: Add new memory instructions
Intel Architecture Instruction Set Extensions Programing
Reference (Oct 2014) describes 3 new memory instructions,
namely clflushopt, clwb and pcommit. Add them to the op
code map and the perf tools new instructions test. e.g.
$ tools/perf/perf test list 2>&1 | grep "x86 ins"
39: Test x86 instruction decoder - new instructions
$ tools/perf/perf test 39
39: Test x86 instruction decoder - new instructions : Ok
Or to see the details:
$ tools/perf/perf test -v 39
