Bug Description

Attempting to run 32bit binaries on arm64 triggers applications to be Killed, as the CONFIG_DEFAULT_MMAP_MIN_ADDR used on armhf is not valid on arm64. While this can be overriden via sysctl, the default should be sane.

I've verified that the config files used to build the Utopic and Trusty kernels currently in proposed (3.16.0-36.48 and 3.13.0-51.84) contain CONFIG_DEFAULT_MMAP_MIN_ADDR set to 32768. I'm thus tagging this bug as verified.
