question on patch files in selinux source package

[John Emrich <john.emrich@xxxxxxxxxxxxx>]

I am running Fedora-18 and have the SELinux policy release 86.fc18.

Installed Packages

Name        : selinux-policy

Arch        : noarch

Version     : 3.11.1

Release     : 86.fc18

Size        : 62  

Repo        : installed

From repo   : updates

Summary     : SELinux policy configuration

URL         : http://oss.tresys.com/repos/refpolicy/

License     : GPLv2+

Description : SELinux Reference Policy - modular.

            : Based off of reference policy: Checked out revision  2.20091117

I downloaded the matching source  selinux-policy-3.11.1-86.fc18.src.rpm 

When installing this I noticed patch files (but no related documentation)

rpmbuild/SOURCES/policy-f18-base.patch

rpmbuild/SOURCES/policy_contrib-rawhide-roleattribute.patch

rpmbuild/SOURCES/policy-f18-contrib.patch

rpmbuild/SOURCES/policy-rawhide-roleattribute.patch

Are these patches just there for reference or do they also need to be applied on top of the 86.fc18.src installation?

Thank You
