A feature of ia64-kdump is that makedumpfile sets p_paddr of region 5 memory section into kdump_sub_header->phys_base. This is only for the diskdump format dump file. As a result, makedumpfile can be newly used with x86 and x86_64 in ia64. The following is a part of mails that Ken'ichi Ohmichi received from Dave Anderson.
