[Bug 2019856] Autopkgtest regression report (util-linux/2.37.2-4ubuntu3.1)

[Ubuntu SRU Bot]

All autopkgtests for the newly accepted util-linux (2.37.2-4ubuntu3.1) for jammy have finished running.
The following regressions have been reported in tests triggered by the package:

cluster-glue/1.0.12-20ubuntu3 (ppc64el)
cmake-extras/1.6-1 (armhf)
kopanocore/8.7.0-7.1ubuntu10 (amd64)
netplan.io/0.105-0ubuntu2~22.04.3 (arm64, armhf, s390x)
node-mqtt/4.2.8-1 (arm64)


Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

Title:
  Add missing ARM-cores to support Grace-based systems

Status in util-linux package in Ubuntu:
  Fix Released
Status in util-linux source package in Jammy:
  Fix Committed
Status in util-linux source package in Kinetic:
  Won't Fix
Status in util-linux source package in Lunar:

Status in util-linux source package in Mantic:

Bug description:
  [Impact]

  When running "lscpu" on a Grace-based system + Ubuntu 22.04, it
  doesn't report a model name:

  Vendor ID: ARM
  Model: 0

  [Fix]

  Adding the additional arm_part to sys-utils/lscpu-arm.c solves the
  problem. The commit below adds the specific codes missing from Jammy's
  version.

  https://github.com/util-linux/util-
  linux/commit/6857cccbb4157d5da34ca98f77a0ac9d68e1e740

  [Test Steps]

  * Verify whether output of lscpu is correct on new CPUs; eg:
  Vendor ID: ARM
  Model name: Neoverse-V2

  * Verify whether output of lscpu doesn't change on old CPUs; eg:
  Vendor ID: ARM
  Model name: Neoverse-N1

  [What Could Go Wrong]

  The fix only introduces additional model identifiers to match
  against and print a model name string, thus regression impact
  should be contained within lscpu and printing cpus model name
  on ARM systems. 

  Output doesn't change on systems with non-affected CPU models.
