Are you sure you sent me the right config?

CONFIG_DYNAMIC_FTRACE_WITH_REGS=y
CONFIG_FUNCTION_PROFILER=y
CONFIG_FTRACE_MCOUNT_RECORD=y
# CONFIG_FTRACE_STARTUP_TEST is not set
CONFIG_MMIOTRACE=y
# CONFIG_HIST_TRIGGERS is not set

HIST_TRIGGERS is not set in your config, which should have made the
histogram trigger tests return UNSUPPORTED.
