Merge tag 'perf-core-for-mingo-4.17-20180215' of... 

Merge tag 'perf-core-for-mingo-4.17-20180215' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/core fixes from Arnaldo Carvalho de Melo:

- perf_mmap overwrite mode fixes/overhaul, prep work to get 'perf top'
  using it, making it bearable to use it in large core count systems
  such as Knights Landing/Mill Intel systems (Kan Liang)

- s/390 now uses syscall.tbl, just like x86-64 to generate the syscall
  table id -> string tables used by 'perf trace' (Hendrik Brueckner)

- Use strtoull() instead of home grown function (Andy Shevchenko)

- Synchronize kernel ABI headers, v4.16-rc1 (Ingo Molnar)

- Document missing 'perf data --force' option (Sangwon Hong)

- Add perf vendor JSON metrics for ARM Cortex-A53 Processor (William Cohen)
