** Description changed: SRU Justification [Impact] Intel has introduced support for their new Emerald Rapids CPU. This support is a nice feature to have in Jammy because it is an LTS release and enabling extra hardware adds to its usability. Usually backporting new features to existing kernels it's not a common practice. But these commits were easy to backport. Most of them were clean cherry picks. Some of them were already picked up from upstream stable releases, and some required manual intervention because Jammy did not have some commits applied but the actual changes were very minimal. - + More information about each commit is addressed inline.
