Merge tag 'powerpc-4.16-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:
 "One notable fix to properly advertise our support for a new firmware
  feature, caused by two series conflicting semantically but not
  textually.

  There's a new ioctl for the new ocxl driver, which is not a fix, but
  needed to complete the userspace API and good to have before the
  driver is in a released kernel.

  Finally three minor selftest fixes, and a fix for intermittent build
  failures for some obscure platforms, caused by a missing make
  dependency.

  Thanks to: Alastair D'Silva, Bharata B Rao, Guenter Roeck"
