fwiw, we can run successfully docker armhf on trusty arm64.

> Docker for arm64 is available from vivid.

so I've installed wily and docker arm64 seems broken:

docker is calling epoll_create, which is replaced with epoll_create1.

I've built docker 1.7.1 from https://github.com/coreos/docker/commits/coreos-1.7.1 which contains some arm64 fixes and it worked fine.
