Kernel artifacts for that test run can be found here:
  https://storage.tuxsuite.com/public/linaro/lkft/builds/2Ricfkwzy9jwZnHXNO=
etymU5t44/

(The labyrinth can be traversed this way: I went from that testrun
link, then test details [clicking on "check-kernel-kfence =E2=80=94 FAIL"],
then "job_url", then "build", then "tuxbuild directory".)
