From: Alexander Graf <[email protected]> When a guest sets its SR entry to invalid, we may still find a corresponding entry in a BAT. So we need to make sure we're not faulting on invalid SR entries, but instead just claim them to be BAT resolved.
This resolves breakage experienced when using libogc based guests.
