Merge tag 'perf-urgent-for-mingo-4.17-20180420' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes and improvements from Arnaldo Carvalho de Melo:
- Store context switch out type in PERF_RECORD_SWITCH[_CPU_WIDE].
The percentage of preempting and non-preempting context switches help
understanding the nature of workloads (CPU or IO bound) that are running
on a machine. This adds the kernel facility and userspace changes needed
to show this information in 'perf script' and 'perf report -D' (Alexey Budankov)
- Remove old error messages about things that unlikely to be the root cause
in modern systems (Andi Kleen)
- Synchronize kernel ABI headers, v4.17-rc1 (Ingo Molnar)
- Support MAP_FIXED_NOREPLACE, noticed when updating the tools/include/
copies (Arnaldo Carvalho de Melo)
- Fixup BPF test using epoll_pwait syscall function probe, to cope with
the syscall routines renames performed in this development cycle (Arnaldo Carvalho de Melo)
- Fix sample_max_stack maximum check and do not proceed when an error
has been detect, return them to avoid misidentifying errors (Jiri Olsa)
- Add '\n' at the end of parse-options error messages (Ravi Bangoria)
- Add s390 support for detailed/verbose PMU event description (Thomas Richter)
