Ahh. "mm_segment_t".

Some other architectures do it in their <asm/segment.h>

And looking at it, we could just do it in thread_info.h itself. I dunno.

At *some* point it would be really nice to try to minimize the header
files, I suspect we spend a lot of time compiling just parsing the
crud most people never need.

(In fact, from my sparse days, I pretty much guarantee that is the case)
