Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

User visible changes:

- Do not print trailing spaces in the hists browser (top, report) to
avoid line wrapping issues when long C++ demangled functions are
sampled (Arnaldo Carvalho de Melo)

- Allow 'perf config' to show --system or --user settings (Taeung Song)

- Add better warning about the need to install the audit-lib-python
package when using perf python scripts (Taeung Song)

- Fix symbol resolution when kernel modules files are only in the
build id cache (~/.debug) (Wang Nan)

Build fixes:

- Fix 'perf test' build on older systems where 'signal' is reserved (Arnaldo Carvalho de Melo)

Infrastructure changes:

- Free the terms list_head in parse_events__free_terms(), also unlink the entries
when deleting them (Wang Nan)

- Fix releasing event_class in 'perf data' fixing integration with
libbabeltrace (Wang Nan)

- Add EXTRA_LDFLAGS option to Makefile (Zubair Lutfullah Kakakhel)

perf config: Add '--system' and '--user' options to select which config file is used

The '--system' option means $(sysconfdir)/perfconfig and '--user' means
$HOME/.perfconfig. If none is used, both system and user config file are

# perf config [<file-option>] [options]

With an specific config file:

# perf config --user | --system

Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

User visible fixes:

- Handle spaces in file names obtained from /proc/pid/maps (Marcin Ślusarz)

New features:

- Improved support for Java, using the JVMTI agent library to do jitdumps
that then will be inserted in synthesized PERF_RECORD_MMAP2 events via
'perf inject' pointed to synthesized ELF files stored in ~/.debug and
keyed with build-ids, to allow symbol resolution and even annotation with
source line info, see the changeset comments to see how to use it (Stephane Eranian)

Documentation changes:

- Document mmore variables in the 'perf config' man page (Taeung Song)

Infrastructure changes:

- Improve a bit the 'make -C tools/perf build-test' output (Arnaldo Carvalho de Melo)

- Do 'build-test' in parallel, using 'make -j' (Arnaldo Carvalho de Melo)

- Fix handling of 'clean' in multi-target make invokations for parallell builds (Jiri Olsa)

Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

User visible changes:

- Rename the "colors.code" ~/.perfconfig variable to "colors.jump_arrows",
as it controls just the that UI element in the annotate browser (Taeung Song)

- Avoid trying to read ELF symtabs from device files, noticed while doing
memory profiling work (Jiri Olsa)

- Improve context detection when offering options in the hists browser,
i.e. some options don't make sense when the browser is not working with
a perf.data file ('perf top' mode), only in 'perf report' mode, like
scripting (Namhyung Kim)

Infrastructure changes:

- Elliminate duplication in the hists browser filter functions, getting the
common part into a function that receives callbacks for filtering by
DSO, thread, etc. (Namhyung Kim)

- Fix misleadingly indented assignment, found using
gcc6 -Wmisleading-indentation (Markus Trippelsdorf)

- Handle LLVM relocation oddities in libbpf, introducing a 'perf test' that
detects such problems and then fixing the problem, so that the test now
passes (Wang Nan)

- More improvements to the build infrastructure to allow reusing the
feature detection facilities (Wang Nan)

- Auto initialize the globals needed by cpu__max_{cpu,node}() routines
(Arnaldo Carvalho de Melo)

Documentation changes:

- Document the perf sysctls in Documentation/sysctl/kernel.txt (Ben Hutchings)

- Document a bunch more ~/.perfconfig knobs (Taeung Song)
