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"
