[GIT PULL 00/29] perf/core improvements and fixes

2016-12-20 Thread Arnaldo Carvalho de Melo 
Hi Ingo,

Please consider pulling, I had most of this queued before your first
pull req to Linus for 4.10, most are fixes, with 'perf sched timehist --idle'
as a followup new feature to the 'perf sched timehist' command introduced in
this window.

One other thing that delayed this was the samples/bpf/ switch to
tools/lib/bpf/ that involved fixing up merge clashes with net.git and also
to properly test it, after more rounds than antecipated, but all seems ok
now and would be good to get this merge issues past us ASAP.

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit e7aa8c2eb11ba69b1b69099c3c7bd6be3087b0ba:

  Merge tag 'docs-4.10' of git://git.lwn.net/linux (2016-12-12 21:58:13 -0800)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git

  samples/bpf: Move open_raw_sock to separate header (2016-12-20 12:00:40 -0300)


perf/core improvements and fixes:

New features:

- Introduce 'perf sched timehist --idle', to analyse processes
  going to/from idle state (Namhyung Kim)

Fixes:

- Allow 'perf record -u user' to continue when facing races with threads
  going away after having scanned them via /proc (Jiri Olsa)

- Fix 'perf mem' --all-user/--all-kernel options (Jiri Olsa)

- Support jumps with multiple arguments (Ravi Bangoria)

- Fix jumps to before the function where they are located (Ravi
Bangoria)

- Fix lock-pi help string (Davidlohr Bueso)

- Fix build of 'perf trace' in odd systems such as a RHEL PPC one (Jiri Olsa)

- Do not overwrite valid build id in 'perf diff' (Kan Liang)

- Don't throw error for zero length symbols, allowing the use of the TUI
  in PowerPC, where such symbols became more common recently (Ravi Bangoria)

Infrastructure:

- Switch of samples/bpf/ to use tools/lib/bpf, removing libbpf
  duplication (Joe Stringer)

- Move headers check into bash script (Jiri Olsa)
