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... -- Kees Cook
