I just noticed this changed from the original patchset I was carrying. On the original, I had a union containing a u32 member to explicitly avoid this casting. Let's wait for comments on the rest of the series, but i'd like to change that back in a v4. Aplogies, I completely missed this on the previous postings ... Thanks /Ilias
