Bug description:
SRU Justification:
==================
[Impact]
* New hardware is not supported by qemu and won't run run, due to
missing hardware CPU model
[Fix]
* 11ba5961a2156a4f210627ed8421387e2531b100 11ba596 "KVM: s390: add
debug logging for cpu model subfunctions"
* 346fa2f891c71a9b98014f8f62c15f4c7dd95ec1 346fa2f "KVM: s390:
implement subfunction processor calls"
* 7832e91cd33f21f3cf82b003478c292915a1ec14 7832e91 "KVM: s390: add
vector enhancements facility 2 to cpumodel"
* d5cb6ab1e3d4d7e0648a167f6290e89f6e86964e d5cb6ab "KVM: s390: add
vector BCD enhancements facility to cpumodel"
* 13209ad0395c4de7fa48108b1dac72e341d5c089 13209ad "KVM: s390: add
MSA9 to cpumodel"
* d668139718a9e2260702777bd8d86d71c30b6539 d668139 "KVM: s390: provide
query function for instructions returning 32 byte"
* 173aec2d5a9fa5f40e462661a8283fcafe04764f 173aec2 "KVM: s390: add
enhanced sort facilty to cpu model"
* 4f45b90e1c03466202fca7f62eaf32243f220830 4f45b90 "KVM: s390: add
deflate conversion facilty to cpu model"
* 8ec2fa52eac53bff7ef1cedbc4ad8af650ec937c 8ec2fa5 "KVM: s390: enable
MSA9 keywrapping functions depending on cpu model"
[Test Case]
* need to be tested by IBM on pre-rel. hardware or simulator
[Regression Potential]
* The regression potential can be considered as low since these
changes are limited to arch/s390
* changes are in support for new and upcoming hardware and shouldn't
affect existing s390x systems
[Other Info]
* the first 2 commits are the key ones, the other 7 are needed to make
them applly cleanly
* these patches are already all included in upstream kernel 5.2, hence
they are in eoan's kernel 5.2
* qemu package SRU in LP 1836154 complements this SRU - for testing
both need to be in place
* I could apply the commit IDs cleanly with 'cherry-picks
--strategy=recursive -X theirs' and checked that no patches on top were pulled
in
