Title:
  Bionic update: upstream stable patchset 2021-02-10

Status in linux package in Ubuntu:
  Invalid
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 2021-02-10

                  Ported from the following upstream stable releases:
                          v4.14.216, v4.19.168,
                                     v4.19.169,
                          v4.14.217, v4.19.170
