Subject: [PATCH] ftrace: fix trace_nop config select


The trace_nop is the tracer that is defined when no tracer is set in
the ftrace infrastructure.

The trace_nop was mistakenly selected by HAVE_FTRACE due to the confusion
between ftrace infrastructure and the ftrace function tracer (which has
been solved by renaming the function tracer).

This patch changes the select to the approriate TRACING.

This patch should fix compile errors on architectures that do not define
the FUNCTION_TRACER.
