So I guess these patches need to go upstream too?

Here's the rest of the u32 coversions. Not all the u32 flags were used for
spinlocks. Most were for the flags instance in the structure.

Note, this patch does _NOT_ include the previous patch that I sent.  If
this needs to go upstream, I'll send the two together as one patch.
