Were this PR created on top of master-next or at least Ubuntu-4.4.0-149.175?

SRU Justification Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from a mainline/stable Linux tree or a minimally backported form of that patch. The following upstream stable patches should be included in the Ubuntu kernel: 4.4.180 upstream stable release from git://git.kernel.org/ The 4.4.180 stable update is a whopping 267 commits, of which we have 53 already applied. In one form or another. Either via embargoed patches (MDS) or SAUCE patches. An addtional 5 commits can be ignore because those changes came in with previous commits. This is a by no means a trivial update so any review is greatly appreciated :-) Compile tested all architectures. Boot tested both in a VM and on barmetal. Ran the ADT tests locally but the results are inconclusive since I get failures for released kernels as well, so can't tell if there's a regression. I'd rather rely on the official release regression tests.
