kernel: stable/longterm updates

- longterm: 3.4.83  -> 3.4.85
 - longterm: 3.10.33 -> 3.10.35
 - longterm: 3.12.14 -> 3.12.15
 - stable:   3.13.7  -> 3.13.8

NOTE: This will break the testing grsec kernel at the moment (there's
not a 3.13.8 patch yet), but it's destined to be upgraded to 3.14 soon
anyway.
