== Development Kernel Justification ==
These two commits from mainlein v4.16-rc1 have been request in Bionic by IBM.

Make the diagnose counters also appear as instruction counters.

The overall instruction counter is larger than the sum of the
single counters. We should try to catch all instruction handlers
to make this match the summary counter.
Let us add sck,tb,sske,iske,rrbe,tb,tpi,tsch,lpsw,pswe....
and remove other unused ones.

== Fixes ==
866c138c3254 ("KVM: s390: diagnoses are instructions as well")
a37cb07a30f0 ("KVM: s390: add vcpu stat counters for many instruction")

== Regression Potential ==
Low.  Limited to s390.
