  [18.04 FEAT] Enhanced hardware support

Status in Ubuntu on IBM z Systems:
  Fix Committed
Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Committed
Status in linux source package in Disco:
  Fix Committed

Bug description:
  SRU Justification:


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


  * 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


  Feature request to apply this to Ubuntu 18.04 in support of new

  Summary:     kernel: report new CPU capabilities

  Description: Add hardware capability bits and features tags to /proc/cpuinfo
  for 4 new CPU features: the "Vector-Enhancements Facility 2",
  the "Vector-Packed-Decimal-Enhancement Facility", the
  "Enhanced-Sort Facility" and the "Deflate-Conversion Facility"
