Hi Linus,

	These are additional changes to the perf tools, on top of what
Ingo has already submitted and you merged, please let me know if I made
any mistake,

	Available from:

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

  # HEAD: 3e9b26dc2268cfbeef85bee095f883264c18425c Remove some duplicated includes

	A summary of what is here:

 - 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.

Best Regards,

- Arnaldo
