From: Alexey Kardashevskiy <[email protected]>
When write to MMIO happens and there is an ioeventfd for that and
is handled successfully, ioeventfd_write() returns 0 (success) and
kvmppc_handle_store() returns EMULATE_DONE. Then kvmppc_emulate_mmio()
converts EMULATE_DONE to RESUME_GUEST_NV and this broke from the loop.
This adds handling of RESUME_GUEST_NV in kvmppc_vcpu_run_hv().
changes in v2:
- as suggesed by Alex Graf on kvm-ppc@, do it with a
helper
