This was reported by Yinghai, but I think he already answered to that.

throughout where?
They're all over the place ;)

My next target would be per-cpu data. But that's because there's _a lot_ 
of code in the tree that got ifdefs between 32 and 64-bit because of 
differences in that, specially irq statistics. A macro would do, but if 
we're gonna do it, let's do it right.
