[GIT PULL 00/17] perf/urgent fixes and improvements

[Arnaldo Carvalho de Melo <acme@kernel.org>]

Hi Ingo,

	Please consider pulling, this took longer than I expected
due to the syscall rename fallout :-\

The following changes since commit 5c8dad48e4f53d6fd0a7e4f95d7c1c983374de88:

  coresight: Move to SPDX identifier (2018-04-19 12:29:41 -0300)

----------------------------------------------------------------
perf/urgent fixes and improvements:

- 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)
