Merge tag 'perf-core-for-mingo-4.19-20180725' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/core

Pull perf/cores fixes and improvements from Arnaldo Carvalho de Melo:

Tools:

top:

- Fix 'struct comm_str' removal crash race, detected with refcount_t
  debugging (Jiri Olsa)

- Use last_match threads cache only in single threaded mode, fixing
  a crash (Jiri Olsa)

record:

- Synthesize GROUP_DESC feature in pipe mode fixing display of
  event groups (Jiri Olsa)

stat:

- Get rid of extra clock display function (Jiri Olsa)

perf script:

- Show correct offsets for DWARF-based unwinding (Sandipan Das)

test:

- Check that complex event name is parsed correctly (Alexey Budankov)

- Fix subtest number when showing results (Thomas Richter)

Arch specific:

arm64:

- Generate syscall table from the kernel sources (asm/unistd.h) like
  other arches do, speeding up the support for new system calls in
  tools such as 'perf trace' (Kim Phillips)

arm:

- Bail out immediatelly on CoreSight hardware tracing instruction sample failure (Leo Yan)

PowerPC:

- Fix record+probe_libc_inet_pton.sh 'perf test' entry (Sandipan Das)

- Callchain IP filtering fixes (Sandipan Das)

S/390:

- Add support for detailed S/390 PMU event description in 'perf list' (Thomas Richter)

- Add transaction flag (-T) support in 'perf stat' for S/390 (Thomas Richter)

- Fix 'perf kvm' S/390 subcommands (Thomas Richter)

Infrastructure:

hists:

- Clarify callchain disabling when available (Arnaldo Carvalho de Melo)

evsel:

- Use perf_evsel__match instead of open coded equivalent (Jiri Olsa)

Documentation:

- Add missing documentation for 'perf list' --desc and --debug options (Sangwon Hong)
