dump: rebase from host-private RAMBlock offsets to guest-physical addresses
RAMBlock.offset --> GuestPhysBlock.target_start
RAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_end
RAMBlock.length --> GuestPhysBlock.target_end -
GuestPhysBlock.target_start
"GuestPhysBlock.host_addr" is only used when writing the dump contents.
This patch enables "crash" to work with the vmcore by rebasing the vmcore
from the left side of the following diagram to the right side:
host-private
offset
relative
to ram_addr RAMBlock guest-visible paddrs
