[Tails-dev] [review'n'merge:1.2] feature/7886-linux-3.16

Hi,

feature/7886-linux-3.16 upgrades the kernel to current sid's 3.16.

Please review'n'merge at least into devel (and most likely, we'll want
to merge into testing too, and cherry-pick the relevant commit into
stable, otherwise these builds will fail as soon as 3.14 is removed
from sid).

Cheers,
