Merge tag 'perf-urgent-for-mingo-4.17-20180602' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
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)
