[SRU][B][D][Patch 0/2] Enhanced hardware support (LP: 1836857)

[frank.heimes at canonical.com]

Buglink: https://bugs.launchpad.net/bugs/1836857

SRU Justification:

[Impact]

* Enhanced hardware support for upcoming machine and make sure it can report new CPU capabilities

[Fix]

* a8fd61688dfad6fdce95fa64cacd8a66595697b8 a8fd616 "s390: report new CPU capabilities"

* 142c52d7bce45d335f48d53fdbf428bb15cf3924 142c52d "s390: add alignment hints to vector load and store"

[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
