I think we probably want to include both crashkernel and pstore as arguments that can disable this randomization.
The carve-outs that pstore uses should already appear in the physical memory mapping that EFI has. (i.e. those things get listed in e820 as non-RAM, etc)
I don't know anything about crashkernel, but if we really do have a lot of these, we likely need to find a way to express them to EFI...
