I am unable to reproduce this on mainline 6.4-rc6 via default cross compiler on a W=1 build. Looking at all other problems reported on the file, it seems something is not right here. Reported build problems around these callbacks, i.e armv8pmu_branch_XXXX() do not make sense as they are available via config CONFIG_PERF_EVENTS which is also enabled along with CONFIG_ARM_PMUV3 in this test config.
