LXD, docker and juju are examples. Ubuntu does not ship with this config, so it is currently not impacted. However, we would like to enable this config to add new hardware support in 15.10. The 15.10 kernel will eventually be provided in trusty as an lts backport, at which point this will begin to break users. [Test Case] Boot an arm64 system with CONFIG_ARM64_PGTABLE_LEVELS=4 enabled in the kernel. Install docker.io and run "docker help". If it fails, you'll see "fatal error: runtime_lfstackpush" followed by a stack trace. If it succeeds, you'll get normal help output. [Regression Risk] The risk of regression is lessened by testing this release on existing Ubuntu kernels w/ 3 level page tables.
