I think we need to get a better handle on this.

It is completely surprising to me that type promotion from u32 to u64
goes through sign extension.

And by "surprising" I mean, it sounds wrong.

Ard, if you could throw me a unified diff of objdump -dr vmlinux, with
and without the u32 cast, I'll take a look at figuring out what's
happening.
