You might want to update your config (make oldconfig?) The latest tip has FUNCTION_TRACER instead of FTRACE.
Also, the config you sent me, does not even have FTRACE on :-/
CONFIG_HAVE_FTRACE=y CONFIG_HAVE_DYNAMIC_FTRACE=y CONFIG_HAVE_FTRACE_MCOUNT_RECORD=y CONFIG_TRACER_MAX_TRACE=y CONFIG_RING_BUFFER=y CONFIG_TRACING=y # CONFIG_FTRACE is not set # CONFIG_IRQSOFF_TRACER is not set # CONFIG_PREEMPT_TRACER is not set # CONFIG_SYSPROF_TRACER is not set CONFIG_SCHED_TRACER=y CONFIG_CONTEXT_SWITCH_TRACER=y
