Merge tag 'perf-core-for-mingo-4.14-20170801' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements from Arnaldo Carvalho de Melo:

User visible changes:

- Beautifiers for the 'cmd' arg of several ioctl types, including:
  sound, DRM, KVM, vhost virtio and perf_events.

  This was done by using scripts that extract the information from
  the UAPI headers, generating string tables that are then used in
  the 'perf trace' syscall argument ioctl beautifier.

  More work needed to further use it, for instance, to use the
  _IOC_DIR value where it is used sanely to suppress the third
  argument, to set formatters for non-pointer values and ultimately
  for using eBPF + pahole-like code to collect + beautify structs in
  the third arg.

  Using the current scheme of having tools/ copies of kernel headers
  we'll make sure tooling stays working when changes are made to the
  kernel ABI headers and will be notified when they get changed,
  reducing the time for 'perf trace' to support new ABIs and allowing
  the tools/perf/ codebase to have the definitions it needs to
  build in dozens of distros/versions, as routinely tested using
  containers for, at this time, 47 environments. (Arnaldo Carvalho de Melo)

Infrastructure changes:

- Clarify header version warning message (Ingo Molnar)

- Sync kernel ABI headers with tooling headers (Ingo Molnar, Arnaldo Carvalho de Melo)
