Subject: [PATCH 4/4] Docs: add a sample asciidoc template

This is just a copy of tracepoints.tmpl (because it was short!) converted

+Introduction
+------------
+
+Tracepoints are static probe points that are located in strategic points
+throughout the kernel. 'Probes' register/unregister with tracepoints
+via a callback mechanism. The 'probes' are strictly typed functions that
+are passed a unique set of parameters defined by each tracepoint.
+
+From this simple callback mechanism, 'probes' can be used to profile, debug,
+and understand kernel behavior. There are a number of tools that provide a
+framework for using 'probes'. These tools include Systemtap, ftrace, and
+LTTng.
+
+Tracepoints are defined in a number of header files via various macros. Thus,
+the purpose of this document is to provide a clear accounting of the available
+tracepoints. The intention is to understand not only what tracepoints are
+available but also to understand where future tracepoints might be added.
+
+The API presented has functions of the form:
++trace_tracepointname(function parameters)+. These are the
+tracepoints callbacks that are found throughout the code. Registering and
+unregistering probes with these callback sites is covered in the
+'Documentation/trace/*' directory.
