Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf update from Ingo Molnar:
"Lots of changes in this cycle as well, with hundreds of commits from
over 30 contributors. Most of the activity was on the tooling side.

Higher level changes:

- New 'perf kvm' analysis tool, from Xiao Guangrong.

- New 'perf trace' system-wide tracing tool

- uprobes fixes + cleanups from Oleg Nesterov.

- Lots of patches to make perf build on Android out of box, from
Irina Tirdea

- Extend ftrace function tracing utility to be more dynamic for its
users. It allows for data passing to the callback functions, as
well as reading regs as if a breakpoint were to trigger at function
entry.

The main goal of this patch series was to allow kprobes to use
ftrace as an optimized probe point when a probe is placed on an
ftrace nop. With lots of help from Masami Hiramatsu, and going
through lots of iterations, we finally came up with a good
solution.

- Add cpumask for uncore pmu, use it in 'stat', from Yan, Zheng.

- Various tracing updates from Steve Rostedt

- Clean up and improve 'perf sched' performance by elliminating lots
of needless calls to libtraceevent.

- Event group parsing support, from Jiri Olsa

- UI/gtk refactorings and improvements from Namhyung Kim

- Add support for non-tracepoint events in perf script python, from
Feng Tang

- Add --symbols to 'script', similar to the one in 'report', from
Feng Tang.

Infrastructure enhancements and fixes:

- Convert the trace builtins to use the growing evsel/evlist
tracepoint infrastructure, removing several open coded constructs
like switch like series of strcmp to dispatch events, etc.
Basically what had already been showcased in 'perf sched'.

- Add evsel constructor for tracepoints, that uses libtraceevent just
to parse the /format events file, use it in a new 'perf test' to
make sure the libtraceevent format parsing regressions can be more
readily caught.

- Some strange errors were happening in some builds, but not on the
next, reported by several people, problem was some parser related
files, generated during the build, didn't had proper make deps, fix
from Eric Sandeen.

- Introduce struct and cache information about the environment where
a perf.data file was captured, from Namhyung Kim.

- Fix handling of unresolved samples when --symbols is used in
'report', from Feng Tang.

- Add union member access support to 'probe', from Hyeoncheol Lee.

- Fixups to die() removal, from Namhyung Kim.

- Render fixes for the TUI, from Namhyung Kim.

- Don't enable annotation in non symbolic view, from Namhyung Kim.

- Fix pipe mode in 'report', from Namhyung Kim.

- Move related stats code from stat to util/, will be used by the
'stat' kvm tool, from Xiao Guangrong.

- Remove die()/exit() calls from several tools.

- Resolve vdso callchains, from Jiri Olsa

- Don't pass const char pointers to basename, so that we can
unconditionally use libgen.h and thus avoid ifdef BIONIC lines,
from David Ahern

- Refactor hist formatting so that it can be reused with the GTK
browser, From Namhyung Kim

- Fix build for another rbtree.c change, from Adrian Hunter.

- Make 'perf diff' command work with evsel hists, from Jiri Olsa.

- Use the only field_sep var that is set up: symbol_conf.field_sep,
fix from Jiri Olsa.

- .gitignore compiled python binaries, from Namhyung Kim.

- Get rid of die() in more libtraceevent places, from Namhyung Kim.

- Rename libtraceevent 'private' struct member to 'priv' so that it
works in C++, from Steven Rostedt

- Remove lots of exit()/die() calls from tools so that the main perf
exit routine can take place, from David Ahern

- Fix x86 build on x86-64, from David Ahern.

- {int,str,rb}list fixes from Suzuki K Poulose

- perf.data header fixes from Namhyung Kim

- Allow user to indicate objdump path, needed in cross environments,
from Maciek Borzecki

- Fix hardware cache event name generation, fix from Jiri Olsa

- Add round trip test for sw, hw and cache event names, catching the
problem Jiri fixed, after Jiri's patch, the test passes
successfully.

- Clean target should do clean for lib/traceevent too, fix from David
Ahern

- Check the right variable for allocation failure, fix from Namhyung
Kim

- Set up evsel->tp_format regardless of evsel->name being set
already, fix from Namhyung Kim

- Oprofile fixes from Robert Richter.

- Remove perf_event_attr needless version inflation, from Jiri Olsa

- Introduce libtraceevent strerror like error reporting facility,
from Namhyung Kim

- Add pmu mappings to perf.data header and use event names from cmd
line, from Robert Richter

- Fix include order for bison/flex-generated C files, from Ben
Hutchings

- Build fixes and documentation corrections from David Ahern

- Assorted cleanups from Robert Richter

- Let O= makes handle relative paths, from Steven Rostedt

- perf script python fixes, from Feng Tang.

- Initial bash completion support, from Frederic Weisbecker

- Allow building without libelf, from Namhyung Kim.

- Support DWARF CFI based unwind to have callchains when %bp based
unwinding is not possible, from Jiri Olsa.

- Symbol resolution fixes, while fixing support PPC64 files with an
.opt ELF section was the end goal, several fixes for code that
handles all architectures and cleanups are included, from Cody
Schafer.

- Assorted fixes for Documentation and build in 32 bit, from Robert
Richter

- Cache the libtraceevent event_format associated to each evsel
early, so that we avoid relookups, i.e. calling pevent_find_event
repeatedly when processing tracepoint events.

[ This is to reduce the surface contact with libtraceevents and
make clear what is that the perf tools needs from that lib: so
far parsing the common and per event fields. ]

- Don't stop the build if the audit libraries are not installed, fix
from Namhyung Kim.

- Fix bfd.h/libbfd detection with recent binutils, from Markus
Trippelsdorf.

- Improve warning message when libunwind devel packages not present,
from Jiri Olsa"

perf tools: Let O= makes handle relative paths

When I did a compile of perf using a relative path for the output
directory, the build failed when it tried to compile libtraceevent. This
is because it continues to use the same relative path when the new
working directory is in a different path.

SUBDIR ../lib/traceevent/
/bin/sh: line 0: cd: ../../../nobackup/perf/: No such file or directory
Makefile:74: *** output directory "../../../nobackup/perf/" does not exist. Stop.
make: *** [../../../nobackup/perf///libtraceevent.a] Error 2

Make the path used an absolute path when building perf with O=.

Boris:

Teach Makefile to check whether the supplied O= directory exists and
bail out if not. Reportedly, kernel dudes are idiots and need to be
guarded so as not to shoot themselves in the foot when playing in the
sandbox.

Pull perf changes from Ingo Molnar:
"Lots of changes:

- (much) improved assembly annotation support in perf report, with
jump visualization, searching, navigation, visual output
improvements and more.

- kernel support for AMD IBS PMU hardware features. Notably 'perf
record -e cycles:p' and 'perf top -e cycles:p' should work without
skid now, like PEBS does on the Intel side, because it takes
advantage of IBS transparently.

- the libtracevents library: it is the first step towards unifying
tracing tooling and perf, and it also gives a tracing library for
external tools like powertop to rely on.

- infrastructure: various improvements and refactoring of the UI
modules and related code

- infrastructure: cleanup and simplification of the profiling
targets code (--uid, --pid, --tid, --cpu, --all-cpus, etc.)

- tons of robustness fixes all around

- various ftrace updates: speedups, cleanups, robustness
improvements.

- typing 'make' in tools/ will now give you a menu of projects to
build and a short help text to explain what each does.

- ... and lots of other changes I forgot to list.

The perf record make bzImage + perf report regression you reported
