Bug Description
SRU Justification:
==================
[Impact]
* Enhanced CPU-MF hardware counters - fix lack of support of new hardware
[Fix]
* 46a984ffb86c854
* 820bace73472271
[Test Case]
* try CPU-Measurement Facility counter on z14 and next generation hardware - only IBM can do that now
[Regression Potential]
* The regression potential can be considered as low since these changes are limited to arch/s390
* do only touch perf_* code
* and mainly add code (rather than modify or remove)
[Other Info]
* first commit is taken from 5.2, second from 5.3-rc1

If it should be added to bionic, it needs to be added to disco, too - to avoid any regressions during dist-upgrades.
So please provide a list of commit IDs (that apply cleanly to bionic master-next and disco master-next), respectively backports for a kernel SRU request.
Changing to Incomplete for now.
