KVM: s390: Make psw available on all exits, not just a subset
commit d7b0b5eb3000c6fb902f08c619fcd673a23d8fab upstream.
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.
