[PATCH 2/3] rteval: Construct a 'model name' on architectures that don't have one

[John Kacur <jkacur@xxxxxxxxxx>]

From: root <root@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>

This is based on an idea from Punit Agrawal <punit1.agrawal@xxxxxxxxxxxxx>

On architectures that lack 'model name' in /proc/cpuinfo
create 'model name' Unknown when creating the per core dictionaries
in cpuinfo

For arm, we can construct the 'model name' from the
'CPU implementer'
'CPU architecture'
'CPU variant'
'CPU part'
'CPU revision'
