Subject: [GIT PULL 00/19] perf/core improvements and fixes
Hi Ingo,
Please consider pulling, it is the pull req from yesterday, minus a patch
that introduced a problem, plus a fex fixes.
I am investigating a problem I noticed for another patch that is upstream
and after that will get back to the removed patch from yesterday's batch,
- Arnaldo
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: Add 'I' event modifier for exclude_idle bit (2015-04-08 11:00:16 -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)
- Add 'I' event modifier for perf_event_attr.exclude_idle bit (Jiri Olsa)
- 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)
- Fix ARM 32 'perf probe' building error (Wang Nan)
- Fix perf_event_attr tests (Jiri Olsa)
Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>
----------------------------------------------------------------
He Kuang (1):
perf evlist: Fix inverted logic in perf_mmap__empty
Jiri Olsa (3):
perf kmem: Respect -i option
perf tests: Fix attr tests
perf tools: Add 'I' event modifier for exclude_idle bit
Namhyung Kim (1):
tools lib traceevent: Honor operator priority
Peter Zijlstra (2):
perf record: Add clockid parameter
perf tools: Merge all perf_event_attr print functions
Wang Nan (3):
perf kmaps: Check kmaps to make code more robust
perf probe: Fix ARM 32 building error
perf report: Don't call map__kmap if map is NULL.
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
