Focal update: v5.4.239 upstream stable release

[Luke Nowakowski-Krijger]

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:

       v5.4.239 upstream stable patchset
       from git://git.kernel.org/

    Note: This patch set is empty for focal because we have already applied
    the one patch in this set
    c9b09cc17fb9 selftests: Fix the executable permissions for fib_tests.sh
