[PATCH 2/2] samples/livepatch: Add README.rst disclaimer

[Joe Lawrence <joe.lawrence@redhat.com>]

The livepatch samples aren't very careful with respect to compiler
IPA-optimization of target kernel functions.

Add a quick disclaimer and pointer to the compiler-considerations.rst
file to warn readers.

+==========
+Disclaimer
+==========
+
+The livepatch sample programs were written with idealized compiler
+output in mind. That is to say that they do not consider ways in which
+optimization may transform target kernel functions.
+
+The samples present only a simple API demonstration and should not be
+considered completely safe.
+
+See the Documentation/livepatching/compiler-considerations.rst file for
+more details on compiler optimizations and how they affect livepatching.
