Sorry, just noticed this. I've got a patch which changes the xive stuff
to the "standard" format this will clash with.

               if (rc == OPAL_BUSY_EVENT) {
                       msleep(OPAL_BUSY_DELAY_MS);
                       opal_poll_events(NULL);
               } else if (rc == OPAL_BUSY) {
                       msleep(OPAL_BUSY_DELAY_MS);
               }

If it's already merged that's fine, I can rebase.

Thanks,
Nick
