Unfortunately this is more work than I can afford putting into it right now. Can we have this fix coming in later? It shouldn't affect anything in this series. The major issue here is that I need to split the root domain into shared and local so that each will have its linear hwirq space therefore get rid of the conversion macros. BUT, the DT binding will break if I do this. I can't think of a simple way to keep the existing binding and do the split. Not without hackery and more magic at least which I don't think would be a better alternative.
