Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/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)"
