Xenial update to 4.4.66 stable release

[Stefan Bader]

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 4.4.66 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.
