Merge tag 'perf-tools-2020-06-02' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tooling updates from Arnaldo Carvalho de Melo:
 "These are additional changes to the perf tools, on top of what Ingo
  already submitted.

   - Further Intel PT call-trace fixes

   - Improve SELinux docs and tool warnings

   - Fix race at exit in 'perf record' using eventfd.

   - Add missing build tests to the default set of 'make -C tools/perf
     build-test'

   - Sync msr-index.h getting new AMD MSRs to decode and filter in 'perf
     trace'.

   - Fix fallback to libaudit in 'perf trace' for arches not using
     per-arch *.tbl files.

   - Fixes for 'perf ftrace'.

   - Fixes and improvements for the 'perf stat' metrics.

   - Use dummy event to get PERF_RECORD_{FORK,MMAP,etc} while
     synthesizing those metadata events for pre-existing threads.

   - Fix leaks detected using clang tooling.

   - Improvements to PMU event metric testing.

   - Report summary for 'perf stat' interval mode at the end, summing up
     all the intervals.

   - Improve pipe mode, i.e. this now works as expected, continuously
     dumping samples:

        # perf record -g -e raw_syscalls:sys_enter | perf --no-pager script

   - Fixes for event grouping, detecting incompatible groups such as:

        # perf stat -e '{cycles,power/energy-cores/}' -v
        WARNING: group events cpu maps do not match, disabling group:
          anon group { power/energy-cores/, cycles }
            power/energy-cores/: 0
            cycles: 0-7

   - Fixes for 'perf probe': blacklist address checking, number of
     kretprobe instances, etc.

   - JIT processing improvements and fixes plus the addition of a 'perf
     test' entry for the java demangler.

   - Add support for synthesizing first/last level cache, TLB and remove
     access events from HW tracing in the auxtrace code, first to use is
     ARM SPE.

   - Vendor events updates and fixes, including for POWER9 and Intel.

   - Allow using ~/.perfconfig for removing the ',' separators in 'perf
     stat' output.

   - Opt-in support for libpfm4"
