A test kernel with those patches backported is available at:

https://kernel.ubuntu.com/~kmously/1818149/

Note there are binaries for multiple arches in that link. The appropriate binaries for the test architecture should be used.

This is for amd64 only, and is based on xenial-hwe instead of bionic.
