Fix compilation on Ubuntu 14.10

Extend the range introduced in 2260bfd to also include Ubuntu's
3.16 kernel. The API-changing patch was also backported to that series.
This will also be required for Trusty users once the the Utopic
hardware-enablement stack, including that 3.16 kernel, comes in.

Refs #838. See comment #2 for the patch in question.
