perf/core improvements and fixes: 

- Optimize sample parsing for ordering events, where we don't need to parse
   all the PERF_SAMPLE_ bits, just the ones leading to the timestamp needed
   to reorder events (Jiri Olsa)
 
 - Use a dummy event to ask for PERF_RECORD_{MMAP,COMM,EXEC} with
   'perf record --delay', when the events asked by the user will only be
   enabled after the workload is started and the requested delay passes,
   so we need to add the dummy event and have it .enabled_on_exec. This
   then allows us to resolve symbols for the DSO executable MMAPs setup
   while we wait for the delay (Arnaldo Carvalho de Melo)
 
 - Synchronize kcmp.h and prctl.h ABI headers wrt SPDX tags (Arnaldo Carvalho de Melo)
 
 - Generalize the annotation code to support other source information
   besides objdump/DWARF obtained ones, starting with python scripts,
   that will is slated to be merged soon (Jiri Olsa)
 
 - Advance the source code lines to right after the column with the
   address in asm lines (Jiri Olsa)
 
 - Fix terminal dimensions resizing signal handling in 'perf top --stdio' (Jiri Olsa)
 
 - Improve error messages for PMU events (Kim Phillips)
 
 - Fix 'perf record' -c/-F options for cpu event aliases (Andi Kleen)
 
 - Enable type checking for perf_evsel_config_term types (Andi Kleen)
 
 - Call machine__exit() at 'perf trace' exit, so as to remove temporary
   files related to VDSO (Andrei Vagin)
 
 - Add "reject" option to parse-events.l, fixing the build with newer
   flex releases. Noticed with flex 2.6.4 on Alpine Linux 3.6 and Edge (Jiri Olsa)
 
 - Document some missing perf.data headers (Andi Kleen)
 
 - Allow printing period for non freq mod groups (Andi Kleen)
 
 - Do not warn the user about kernel.kptr_restrict when not sampling the
   kernel (Arnaldo Carvalho de Melo)
 
 - Fix bug in 'perf help' introduced during conversion to strstart() (Namhyung Kim)
 
 - Do not truncate ASM instruction mnemonics at 6 characters in the annotation
   output, PowerPC has long ones (Ravi Bangoria)
 
 - Document some missing command line options (Sihyeon Jang)
 
 - Update POWER9 vendor event tables (Sukadev Bhattiprolu)
 
 - Fix 'perf test' shell entries on s390x, where the 'openat' syscall
   is used instead of 'open' in one of the tests and
 
 - No need to use overwrite mmap mode in 'perf test', those tests
   do not generate massive amount of events to fill the ring buffer (Wang Nan)
 
 - Add missing command line options (mostly --force/-f) to the man pages (Sihyeon Jang)
