There are some locations where we check if the return value of a service
indicates that we should resume the guest. This patch introduces a helper
to handle the two possible values we currently have:
- RESUME_GUEST
- RESUME_GUEST_NV
Since it only affects Book3S HV for now, the helper is added to
the kvm_book3s.h header file.
