Well maybe in the future.
One of the issues that I ran into is that I had to place the cpu area in between to make the offsets link right.
However, it would be best if the cpuarea came *after* the modules area. We only need linking that covers the per cpu area of processor 0.
So I think we have a 2GB area right?
1GB kernel 1GB - 1x per cpu area (128M?) modules? cpu aree 0 ---- 2GB limit cpu area 1 cpu area 2 ....
For that we would need to move the kernel down a bit. Can we do that?
