Will Utopic be 3.16 based? If so, once 24f2e0273f80ec262a772059e140a0adef35296d is in the Ubuntu kernel, it will be possible to enable CONFIG_RANDOMIZE_BASE along with CONFIG_HIBERNATE on i386 and amd64.
Otherwise, please backport a6e15a39048ec3229b9a53425f4384f55f6cc1b3 and 24f2e0273f80ec262a772059e140a0adef35296d from Linus's tree. They should apply easily to 3.15.
