Not to mention, that there's no explanation for why makedumpfile would filter
out this crucial page:

> crash: page excluded: kernel virtual address: ffffffff81bb3b00 type: "cpu number (per_cpu)"
> crash: page excluded: kernel virtual address: ffffffff81bb3b00 type: "cpu number (per_cpu)"

I wouldn't think that *any* page in the mapped kernel-text/static-data
region would be subject to filtering -- certainly not the one containing
the per-cpu data information.
