When we receive intercept a DIAG_9C from the guest we verify
that the target real CPU associated with the virtual CPU
designated by the guest is running and if not we forward the
DIAG_9C to the target real CPU.
To avoid a diag9c storm we allow a maximal rate of diag9c forwarding.
The rate is calculated as a count per second defined as a
new parameter of the s390 kvm module: diag9c_forwarding_hz .
The default value is to not forward diag9c.
Before Conny starts yelling I'll do it myself:

yes, it comes soon.
