Merge tag 'perf-urgent-for-mingo-4.18-20180730' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

- Update the tools copy of several files, including perf_event.h,
  powerpc's asm/unistd.h (new io_pgetevents syscall), bpf.h and
  x86's memcpy_64.s (used in 'perf bench mem'), silencing the
  respective warnings during the perf tools build.

- Fix the build on the alpine:edge distro.
