 tagger Arnaldo Carvalho de Melo <acme@redhat.com> 1524234378 -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)
