So I haven't got the Travis target merged upstream yet. You can find
them here with your patches:

  https://github.com/stsquad/qemu/tree/review/cmpxchg-atomics-v5-travis-debug

With which:

  make docker-run-test-build@travis TARGET_LIST=aarch64-softmmu J=9

will show you the failure (modify J for cores ;-)
