User visible:
- Use PERF_RECORD_SWITCH when available in intel-pt, instead of
"sched:sched_switch" events, enabling an unprivileged user to trace
multi-threaded or multi-process workloads (Adrian Hunter)
- Always use non inlined file name for 'srcfile' sort key (Andi Kleen)

backend-stalled-cycles (Andi Kleen)
Infrastructure:
- Add a 'perf test' entry for decoding of new x86 instructions (Adrian Hunter)
- Add new instructions (sha, clflushopt, clwb, pcommit, rdpkru, wrpkru, xsavec,
xsaves, xrstors) to the x86 instruction decoder (Adrian Hunter)
- Add a build test to warn when source code drifts happen for the
instruction decoder files in the kernel and in tools/perf (Adrian Hunter)
- Copy linux/filter.h to tools/include (He Kuang)
- Support function __get_dynamic_array_len in libtraceevent (He Kuanguuu)
- Tracing path finding/mounting/error reporting refactorings (Jiri Olsa)
