I have prepared a Fedora kernel test-build with the patch added, this is
currently building here:
https://koji.fedoraproject.org/koji/taskinfo?taskID=54473681

Note it takes a couple of hour for the build to complete.

See here for some generic instructions on installing a kernel test-build
directly from koji (the Fedora buildsystem):

You will need to disable secure-boot I'm afraid as test kernel-builds are not
signed.

If you cannot do this from within your BIOS you can instead run:

mokutil --disable-validation

This will ask you to pick a password (I would advise using 123456789) and then
on reboot will ask you to enter the nth char of the password a couple of times,
to prove you have physical access to the machine *and* that it was you who
requested the change.

This temporarily disables validation at the shim level, once you are done you
can re-enable validation by running:

mokutil --enable-validation
