Merge tag 'perf-urgent-for-mingo-4.16-20180306' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
- Be more robust when drawing arrows in the annotation TUI, avoiding a
segfault when jump instructions have as a target addresses in functions
other that the one currently being annotated. The full fix will come in
the following days, when jumping to other functions will work as call
instructions (Arnaldo Carvalho de Melo)
- Prevent auxtrace_queues__process_index() from queuing AUX area data for
decoding when the --no-itrace option has been used (Adrian Hunter)
- Sync copy of kvm UAPI headers and x86's cpufeatures.h (Arnaldo Carvalho de Melo)
- Fix 'perf stat' CSV output format for non-supported counters (Ilya Pronin)
- Fix crash in 'perf record|perf report' pipe mode (Jiri Olsa)
- Fix annoying 'perf top' overwrite fallback message on older kernels (Kan Liang)
- Fix the usage on the 'perf kallsyms' man page (Sangwon Hong)
