[Secure-testing-team] Bug#820008: Support for securelevel and Secure Boot

[Ben Hutchings]

Package: src:linux
Version: 4.5-1~exp1
Severity: important
Tags: security

To ensure the integrity of the kernel, we should support a securelevel
where all modules must be signed by a trusted key and all APIs
allowing arbitrary memory writes are disabled.

To meet Secure Boot requirements, we need to turn this on whenever
booted with SB enabled.

Ben.
