Merge tag 'perf-tools-fixes-for-v5.9-2020-09-01' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Fix infinite loop in the TUI for grouped events in 'perf top/record',
eg when using "perf top -e '{cycles,instructions,cache-misses}'".
- Fix segfault by skipping side-band event setup if HAVE_LIBBPF_SUPPORT
is not set.
- Fix synthesized branch stacks generated from CoreSight ETM trace and
Intel PT hardware traces.
- Fix error when synthesizing events from ARM SPE hardware trace.
- The SNOOPX and REMOTE offsets in the data_src bitmask in perf records
were were both 37, SNOOPX is 38, fix it.
- Fix use of CPU list with summary option in 'perf sched timehist'.
- Avoid an uninitialized read when using fake PMUs.
- Set perf_event_attr.exclude_guest=1 for user-space counting.
- Don't order events when doing a 'perf report -D' raw dump of
perf.data records.
- Set NULL sentinel in pmu_events table in "Parse and process metrics"
'perf test'
- Fix basic bpf filtering 'perf test' on s390x.
- Fix out of bounds array access in the 'perf stat' print_counters()
evlist method.
- Add mwait_idle_with_hints.constprop.0 to the list of idle symbols.
- Use %zd for size_t printf formats on 32-bit.
- Correct the help info of "perf record --no-bpf-event" option.
- Add entries for CoreSight and Arm SPE tooling to MAINTAINERS.
