Hi All, Whilst I'll give up at some point and just apply this without additional tags I really don't like doing that as I've made too many idiot mistakes in the past. Some of these are fairly trivial so please can people take a look if they have a chance. Rob did the DT one (thanks!) so we are down to... > > 12 - The big irq rework patch.
