Bionic update: upstream stable patchset 2020-04-27

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 2020-04-27

                Ported from the following upstream stable releases:
                        v4.14.177, v4.19.117
                                   v4.19.118
