Merge tag 'perf-core-for-mingo-20160712' 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:
- Add demangling of symbols in programs written in the Rust language (David Tolnay)
- Add support for tracepoints in the python binding, including an example, that
sets up and parses sched:sched_switch events, tools/perf/python/tracepoint.py
(Jiri Olsa)
- Introduce --stdio-color to set up the color output mode selection in
'annotate' and 'report', allowing emit color escape sequences when
redirecting the output of these tools (Arnaldo Carvalho de Melo)
Infrastructure changes:
- Various tweaks to allow the 'perf trace' beautifiers to build without using
kernel headers and in a wider range of Linux distributions/releases
(Arnaldo Carvalho de Melo)
- Stop using kernel source files, instead copy what is needed and
check when the original kernel source file gets modified, warning
the developers about it. This helps in building the tool in older
systems and even in recent ones, for just added kernel features
for which ABI details (struct changes, defines, etc) still are not
available on system headers (Arnaldo Carvalho de Melo)
- Be consistent in how to use strerror_r, adding a wrapper that makes sure that
it returns a pointer to passed buffer, and using the XSI variant, that is
available in more libc implementations (Arnaldo Carvalho de Melo)
- Avoid checking code drift on busibox's diff perf intel-pt-decoder, as it
doesn't have the '-I' command line switch to check for regexps
(Arnaldo Carvalho de Melo)
- Add missing headers in various places (Arnaldo Carvalho de Melo)
- Remove unneeded headers from various other places (Arnaldo Carvalho de Melo)
- Add feature detection for gelf_getnote(), disabling SDT support if not
present (Arnaldo Carvalho de Melo)
- Fix oddities with GCC 5.3.0 by initializing some variables
(Arnaldo Carvalho de Melo)
- With those changes in place perf now builds on Alpine Linux 3.4, in addition to
on centos (5, 6, 7), debian (7, 8, experimental), fedora (21, 22, 23, 24, rawhide),
mageia 5, opensuse (13.2, 42.1) and ubuntu (12.04.5, 14.04.4, 15.10, 16.04) and
will be test build on those systems prior to future pull requests.

+ * Any path component not starting with a XID_Start character is prefixed with
+ * "_".
