Comment (by erikd):

 Large address space should work on Arm64. At least it does on the server
 grade machine that I', testing on. Interestingly I had reduce the mmap
 size from 1TB to 1/4 TB (see commit 38c98e4f6).

 I'm currently doing my testing on  base machine with Ubuntu 15.04 but
 doing all my testing in a Debian Chroot. The base kernel is
 `3.19.0-31-generic #36-Ubuntu SMP`.

 Can you tell tell which tests fail with the above error message?
