commit 096ea522e84ea68f8e6c41e5e7294731a81e29bc upstream.
Recent versions of sphinx will emit messages like:
Documentation/sphinx/kerneldoc.py:103: RemovedInSphinx20Warning: app.warning() is now deprecated. Use sphinx.util.logging instead.
Switch to sphinx.util.logging to make this unsightly message go away. Alas, that interface was only added in version 1.6, so we have to add a version check to keep things working with older sphinxes.
