linux: 4.4.0-139.165 -proposed tracker

Hardware Certification have begun testing this -proposed kernel.

Hardware Certification have completed testing this -proposed kernel. No regressions were observed, results are available here: http://people.canonical.com/~hwcert/sru-testing/xenial/4.4.0-139.165/xenial-proposed-published.html

on the snap testing, it fails test_095_kernel_symbols_missing from the kernel security tests because it is unable to read /proc/self/stack as a normal user. Can you confirm if this is expected?

======================================================================
FAIL: test_095_kernel_symbols_missing (test_kernel_security.KernelSecurityTest)
kernel addresses in kallsyms and modules are zeroed out

@Paul Larson: This is expected. The commit "c714676a18f1 proc: restrict kernel stack dumps to root" (part of the update to upstream stable 4.4.160) changed the permissions of /proc/self/stack so that it requires either root or CAP_SYS_ADMIN

I think the test will need to be updated

Verification tests completed with the following exceptions:
- bug 1775068: Xenial is not the original series used by the bug reporter.
- bug 1797314: fix verified with Bionic, reporter doesn't have a Xenial setup for verification.
