perf/core improvements and fixes:
- Support syscall name glob matching in 'perf trace' (Arnaldo Carvalho de Melo)
e.g.:
# perf trace -e pkey_*
32.784 (0.006 ms): pkey/16018 pkey_alloc(init_val: DISABLE_WRITE) = -1 EINVAL Invalid argument
32.795 (0.004 ms): pkey/16018 pkey_mprotect(start: 0x7f380d0a6000, len: 4096, prot: READ|WRITE, pkey: -1) = 0
32.801 (0.002 ms): pkey/16018 pkey_free(pkey: -1 ) = -1 EINVAL Invalid argument
^C#
- Do not auto merge counts for explicitely specified events in
'perf stat' (Arnaldo Carvalho de Melo)
- Fix syntax in documentation of .perfconfig intel-pt option (Jack Henschel)
- Calculate the average cycles of iterations for loops detected by the
branch history support in 'perf report' (Jin Yao)
- Support PERF_SAMPLE_PHYS_ADDR as a sort key "phys_daddr" in the 'script', 'mem',
'top' and 'report'. Also add a test entry for it in 'perf test' (Kan Liang)
- Fix 'Object code reading' 'perf test' entry in PowerPC (Ravi Bangoria)
- Remove some duplicate Power9 duplicate vendor events (described in JSON
files) (Sukadev Bhattiprolu)

perf annotate browser: Help for cycling thru hottest instructions with TAB/shift+TAB
The popup help accessed via 'h' wasn't mentioning about TAB and
shift-TAB, just about 'H', which goes to the hottest line, while the
former two are the hotkeys for actually cycling thru the hottest lines.
