Do not instrument the tracer itself:

ifdef CONFIG_FUNCTION_TRACER ORIG_CFLAGS := $(KBUILD_CFLAGS) KBUILD_CFLAGS = $(subst -pg,,$(ORIG_CFLAGS))

selftest needs instrumentation

CFLAGS_trace_selftest_dynamic.o = -pg obj-y += trace_selftest_dynamic.o endif

If unlikely tracing is enabled, do not trace these files

ifdef CONFIG_TRACING_BRANCHES KBUILD_CFLAGS += -DDISABLE_BRANCH_PROFILING endif

Make the trace clocks available generally: it's infrastructure

relied on by ptrace for example:

obj-y += trace_clock.o

obj-$(CONFIG_FUNCTION_TRACER) += libftrace.o obj-$(CONFIG_RING_BUFFER) += ring_buffer.o obj-$(CONFIG_RING_BUFFER_BENCHMARK) += ring_buffer_benchmark.o
