Howdy,
I setup your patch under an /usr/src/kernel/rpmbuild tree for current
"kernel-4.11.8-200.fc25.src.rpm" and made below change to kernel.spec
file together with an rpmbuild -ba cycle on SPECS/kernel.spec.

From an 'rpmbuild -ba kernel.spec' nicely proceeded and generated all
package. They all installed and the system boots and works like a charm!
