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" * tag 'powerpc-4.16-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/pseries: Fix vector5 in ibm architecture vector table ocxl: Document the OCXL_IOCTL_GET_METADATA IOCTL ocxl: Add get_metadata IOCTL to share OCXL information to userspace selftests/powerpc: Skip the subpage_prot tests if the syscall is unavailable selftests/powerpc: Fix missing clean of pmu/lib.o powerpc/boot: Fix random libfdt related build errors selftests/powerpc: Skip tm-trap if transactional memory is not enabled
