Hi, This is rev 2 of the series. The main change is I've moved the helper into it's own patch and changed it's return to a bool rather than try and straddle the different return semantics of kvm_handle_mmio_return and handle_exit. The result is we no longer have code motion in patch 2 (now 3) to introduce the helper making it embarrassingly short - but hopefully a lot clearer. As usual revision details bellow the --- in each patch.
