AppArmor wise the zesty kernel has a set of fixes on that have not been released yet for xenial, or yakkety. However I wouldn't expect that set of patches to result in a change around file_mmap (at least not directly).
We could try a xenial kernel with the set of patches on it that are in zesty http://people.canonical.com/~jj/linux+jj/
and I can try bisecting zesty to identify what is causing this change
