Merge branch 'perf-urgent-for-linus' of git://git./linux/kernel/git/tip/tip

Pull more perf tooling updates from Thomas Gleixner:
 "Perf tool updates and fixes:

  perf stat:

   - Display user and system time for workload targets (Jiri Olsa)

  perf record:

   - Enable arbitrary event names thru name= modifier (Alexey Budankov)

  PowerPC:

   - Add a python script for hypervisor call statistics (Ravi Bangoria)

  Intel PT: (Adrian Hunter)

   - Fix sync_switch INTEL_PT_SS_NOT_TRACING

   - Fix decoding to accept CBR between FUP and corresponding TIP

   - Fix MTC timing after overflow

   - Fix "Unexpected indirect branch" error

  perf test:

   - record+probe_libc_inet_pton:
      - To get the symbol table for dynamic shared objects on ubuntu we
        need to pass the -D/--dynamic command line option, unlike with
        the fedora distros (Arnaldo Carvalho de Melo)

   - code-reading:
      - Fix perf_env setup for PTI entry trampolines (Adrian Hunter)

   - kmod-path:
      - Add tests for vdso32 and vdsox32 (Adrian Hunter)

   - Use header file util/debug.h (Thomas Richter)

  perf annotate:

   - Make the various UI backends (stdio, TUI, gtk) use more
     consistently structs with annotation options as specified by the
     user (Arnaldo Carvalho de Melo)

   - Move annotation specific knobs from the symbol_conf global kitchen
     sink to the annotation option structs (Arnaldo Carvalho de Melo)

  perf script:

   - Add more PMU fields to python scripts event handler dict (Jin Yao)

  Core:

   - Fix misleading error for some unparsable events mentioning PMUs
     when those are not involved in the problem (Jiri Olsa)

   - Consider BSS symbols when processing /proc/kallsyms ('B' and 'b')
     (Arnaldo Carvalho de Melo)

   - Be more robust when trying to use per-symbol histograms, checking
     for unlikely but possible cases where the space for the histograms
     wasn't allocated, print a debug message for such cases (Arnaldo
     Carvalho de Melo)

   - Fix symbol and object code resolution for vdso32 and vdsox32
     (Adrian Hunter)

   - No need to check for null when passing pointers to foo__get() style
     refcount grabbing helpers, just like in the kernel and with free(),
     its safe to pass a NULL pointer to avoid having to check it before
     each and every foo__get() call (Arnaldo Carvalho de Melo)

   - Remove some dead code (quote.[ch]) (Arnaldo Carvalho de Melo)

   - Remove some needless globals, making them local (Arnaldo Carvalho
     de Melo)

   - Reduce usage of symbol_conf.use_callchain, using other means of
     finding out if callchains are in use or available for specific
     events, as we evolved this codebase to allow requesting callchains
     for just a subset of the monitored events. In time it will help
     polish recording and showing mixed sets accross the various tools:

        perf record -e cycles/call-graph=fp/,cache-misses/call-graph=dwarf/,instructions'

     (Arnaldo Carvalho de Melo)

   - Consider PTI entry trampolines in map__rip_2objdump() (Adrian
     Hunter)"
