Bionic update: upstream stable patchset 2018-05-29

[Kamal Mostafa]

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:

       upstream stable patchset 2018-05-29 (ported from v4.14.37 and v4.16.5)
       from git://git.kernel.org/
