Bug description:
SRU justification:
Impact: A race in context flushing is causing a kernel panic on the
s390x architecture.
Fix: Using a set of 3 patches (all restricted to arch code), one
already upstream and the other 2 pending on linux-next. Regression
risk should be low (limited to arch code and tested).
Testcase: see below

The problem happened randomly. Not pattern has been figured out yet.
It also happens on below kernel levels.

Heinz-Werner, what do you mean by "use case"? Could you elaborate it?
If you are referring to what application caused this problem. We have
machine learning running on Ubuntu on the IBM Z community cloud.
The dump file is big, any suggestion of the location to upload the
dump file?
