[SRU][Focal][PULL] Focal update: v5.4.100 upstream stable release

[Kamal Mostafa]

This pull request (16 commits) includes the following Focal stable patchsets:

	Focal update: v5.4.100 upstream stable release
	https://bugs.launchpad.net/bugs/1918168

Note also that the 'stable-next' branch head contains this and all prior
pending upstream stable releases.  I recommend fetching and applying just this
reference ('stable-next') instead of each tags/focal-stable-v5.4.xx reference:

   git://kernel.ubuntu.com/ubuntu-stable/ubuntu-stable-focal.git stable-next
