Hi Ingo,

	Please consider pulling,

- Arnaldo

The following changes since commit c5ab6ad7f627f031e2bbde575c7e6e27ea36da55:

  Merge tag 'perf-core-for-mingo-20160413' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2016-04-13 20:27:58 +0200)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-20160414

for you to fetch changes up to 860b8d4b3f893c97f905b978ecf62f48816dc5de:

  perf config: Make show_config() use perf_config_set (2016-04-14 09:15:47 -0300)

----------------------------------------------------------------
perf/core improvements:

User visible:

- Introduce 'perf record --timestamp-filename', to add a timestamp
  at the end of the 'perf data' file. Will get added value when
  the patch to make 'perf.data' file snapshots gets merged (Wang Nan)

- Fix display of variables present in both --config and --user in
  'perf list' (Taeung Song)

Build fixes:

- Add seccomp and getradom beautifier related defines to fix
  the build in older systems where those definitions are not
  available (Arnaldo Carvalho de Melo)

#1378800 — [PATCH 01/11] perf trace: Add seccomp beautifier related defines for older systems

FromArnaldo Carvalho de Melo <acme@kernel.org>
Date2016-04-14 14:40 +0200
Subject[PATCH 01/11] perf trace: Add seccomp beautifier related defines for older systems
Message-ID<rnOIY-1Cp-59@gated-at.bofh.it>
In reply to#1378794
From: Arnaldo Carvalho de Melo <acme@redhat.com>

Were the detached tarball (make perf-tar-src-pkg) build was failing because
those definitions aren't available in the system headers.

On RHEL7, for instance:

  builtin-trace.c: In function ‘syscall_arg__scnprintf_seccomp_op’:
  builtin-trace.c:1069:7: error: ‘SECCOMP_SET_MODE_STRICT’ undeclared (first use in this function)
    P_SECCOMP_SET_MODE_OP(STRICT);
         ^
  builtin-trace.c:1069:7: note: each undeclared identifier is reported only once for each function it appears in
  builtin-trace.c:1070:7: error: ‘SECCOMP_SET_MODE_FILTER’ undeclared (first use in this function)
    P_SECCOMP_SET_MODE_OP(FILTER);
         ^
  builtin-trace.c: In function ‘syscall_arg__scnprintf_seccomp_flags’:
  builtin-trace.c:1091:14: error: ‘SECCOMP_FILTER_FLAG_TSYNC’ undeclared (first use in this function)
    P_FLAG(TSYNC);
                ^
