Title:
  Bionic update: upstream stable patchset 2019-07-12

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Bionic:
  Fix Committed

Bug description:
  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 2019-07-12

         Ported from the following upstream stable releases:
              v4.14.75, v4.18.13,
              v4.14.76, v4.18.14,
              v4.14.77, v4.18.15
