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) Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Ingo Molnar --- c042f7e9bb6ad9429ea0f2c9138dc06413198967
