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)
