%changelog
* Tue Sep 03 2013 Kyle McMartin <kyle@redhat.com>
- Pull in some Calxeda highbank fixes that are destined for 3.12
- Add a %with_extra twiddle to disable building kernel-modules-extra
subpackages.
- Fix dtbs install path to use %install_image_path (not that it's different
at the moment.)
* Tue Sep 03 2013 Josh Boyer <jwboyer@fedoraproject.org>
- Add keyring patches to support krb5 (rhbz 1003043)
