Merge reason: hw-breakpoints perf integration is looking
good in testing and in reviews, plus conflicts
are mounting up - so merge & resolve.

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
