Pull perf/urgent fixes from Carvalho de Melo:

- Update prctl and cpufeatures.h tools/ copies with the kernel sources
  originals, which makes 'perf trace' know about the new prctl options
  for speculation control and silences the build warnings (Arnaldo Carvalho de Melo)

- Update insn.h in Intel-PT instruction decoder with its original from from the
  kernel sources, to silence build warnings, no effect on the actual tools this
  time around (Arnaldo Carvalho de Melo)
