Subject: [GIT PULL 00/16] perf/core improvements and fixes

Hi Ingo,

	Please consider pulling,

The following changes since commit 6645f3187f5beb64f7a40515cfa18f3889264ece:

  Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2015-04-03 07:00:02 +0200)

  perf tools: Merge all perf_event_attr print functions (2015-04-07 13:25:05 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

- Teach about perf_event_attr.clockid to 'perf record' (Peter Zijlstra)

- perf sched replay improvements for high CPU core count machines (Yunlong Song)

- Consider PERF_RECORD_ events with cpumode == 0 in 'perf top', removing one
  cause of long term memory usage buildup, i.e. not processing PERF_RECORD_EXIT
  events (Arnaldo Carvalho de Melo)

- Respect -i option 'in perf kmem' (Jiri Olsa)

Infrastructure:

- Honor operator priority in libtraceevent (Namhyung Kim)

- Merge all perf_event_attr print functions (Peter Zijlstra)

- Check kmaps access to make code more robust (Wang Nan)

- Fix inverted logic in perf_mmap__empty() (He Kuang)

Yunlong Song (9):
      perf sched replay: Use struct task_desc instead of struct task_task for correct meaning
      perf sched replay: Increase the MAX_PID value to fix assertion failure problem
      perf sched replay: Alloc the memory of pid_to_task dynamically to adapt to the unexpected change of pid_max
      perf sched replay: Realloc the memory of pid_to_task stepwise to adapt to the different pid_max configurations
      perf sched replay: Fix the segmentation fault problem caused by pr_err in threads
      perf sched replay: Handle the dead halt of sem_wait when create_tasks() fails for any task
      perf sched replay: Fix the EMFILE error caused by the limitation of the maximum open files
      perf sched replay: Support using -f to override perf.data file ownership
      perf sched replay: Use replay_repeat to calculate the runavg of cpu usage instead of the default value 10
