Bug Description
SRU Justification:
==================
[Impact]
* Enhanced hardware support for upcoming machine and make sure it can report new CPU capabilities
[Fix]
* a8fd61688dfad6f
* 142c52d7bce45d3
[Test Case]
* check /proc/cpuinfo in bionic running on upcoming machine - currently only IBM can do that
[Regression Potential]
* The regression potential can be considered as very low since these changes are limited to arch/s390
* and mainly adds code for the capability to report new features in cpuinfo - in case of running on new hardware
[Other Info]
* a8fd616 got upstream accepted with 5.2; 142c52d with 5.1 - hence both are already in eoan
