perf/core improvemends and fixes for v4.14:

Browse source

New features:
 
 - Filter out 'sshd' in the tracer ancestry in 'perf trace' syswide tracing,
   to elliminate tracing loops (Arnaldo Carvalho de Melo)
 
 - Support lookup of symbols in other mount namespaces in 'perf top' (Krister Johansen)
 
 - Initial 'clone' syscall args beautifier in 'perf trace' (Arnaldo Carvalho de Melo)
 
 User visible:
 
 - Ignore 'fd' and 'offset' args for MAP_ANONYMOUS in 'perf trace'
   (Arnaldo Carvalho de Melo)
 
 - Process tracing data in 'perf annotate' pipe mode (David Carrillo-Cisneros)
 
 - Make 'perf report --branch-history' work without callgraphs(-g) option
   in perf record (Jin Yao)
 
 - Tag branch type/flag on "to" and tag cycles on "from" in 'perf report' (Jin Yao)
 
 Fixes:
 
 - Fix jvmti linker error when libelf config is disabled (Sudeep Holla)
 
 - Fix cgroups refcount usage (Arnaldo Carvalho de Melo)
 
 - Fix kernel symbol adjustment for s390x (Thomas Richter)
 
 - Fix 'perf report --stdio --show-total-period', it was showing the
   number of samples, not the total period (Taeung Song)
 
 Infrastructure:
 
 - Add perf_sample dictionary to tracepoint handlers in 'perf script'
   python, which were already present for other types of events
   (hardware, etc) (Arun Kalyanasundaram)
 
 - Make build fail on vendor events JSON parse error (Andi Kleen)
 
 - Adopt strstarts() from the kernel (Arnaldo Carvalho de Melo)
 
 Arch specific:
 
 - Set no_aux_samples for the tracking event in Intel PT (Kan Liang)
 
 - Always set no branch for Intel PT dummy event (Kan Liang)
 
 Trivial:
 
 - Simplify some error handlers in 'perf script' (Dan Carpenter)
 
 - Add EXCLUDE_EXTLIBS and EXTRA_PERFLIBS to makefile (David Carrillo-Cisneros)
