[SRU][Jammy][PULL] Jammy update: v5.15.50 upstream stable release

[Kamal Mostafa]

This pull request (9 commits) includes the following Jammy stable patchsets:

	Jammy update: v5.15.50 upstream stable release
	https://bugs.launchpad.net/bugs/1986715

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/jammy-stable-v5.15.xx reference:

   git://git.launchpad.net/~ubuntu-kernel-stable/+git/jammy stable-next
