Carsten Otte d7b0b5eb30 KVM: s390: Make psw available on all exits, not just a subset
This patch moves s390 processor status word into the base kvm_run
struct and keeps it up-to date on all userspace exits.

The userspace ABI is broken by this, however there are no applications
in the wild using this.  A capability check is provided so users can
verify the updated API exists.
