[Impact]
When running "lscpu" on a Vera-based system, 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 Noble's
(and previous) versions.
https://github.com/util-linux/util-
linux/commit/908777470d403ec30c525472ba0d3701c9c5a223
[Test Steps]
* Verify whether output of lscpu is correct on new CPUs; eg:
Vendor ID: ARM
Model name: Olympus
* 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.
