See the src.rpm package. All patchs are there.

        Finally, there is a small set of bug fixes and patches to ease
        the build process on various architectures. Overall, the Fedora
        kernel suggests that, in Red Hat's view, not a whole lot needs
        to be added to the 2.6 kernel (the upcoming 2.6.6 version, at
        least) for it to be ready for wide use.
