>This patch makes the vmcore utilities (ex. crash, makedumpfile) be
>able to get the relocation address of the xen hypervisor from a
>vmcore. It is necessary for the utilities to find the data of the
>hypervisor structures.
>
>Note that this patch does not raise any comptibility issue for the
>utilities (which I know) nor the other components of xen.
