Just read your other mails too. If I see it correctly, there's only one
place which has "GART":
$ git grep -e \"GART\"
arch/x86/kernel/crash.c:235: walk_iomem_res("GART", IORESOURCE_MEM, 0, -1,
So crash.c only excludes this region but the kernel doesn't create it.
Right?
So we can kill that walk_iomem_res(), as you say. Which would be even
nicer...
