perf/core improvements and fixes:

- Be consistent when checking if a perf_mmap instance had
  its ring buffer unmmaped, fixing segfaults noticed in
  'perf trace' (Kan Liang, Arnaldo Carvalho de Melo)

- Avoid adding the same option multiple times to the 'diff'
  command in check-headers.sh (Jiri Olsa)

- Add vendor event files (JSON format) to various IBM
  s390 models (z10EC, z10BC, z196, zEC12, zBC12, z13
  and z14) (Thomas Richter)
