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
