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.Since it both changes the size of the crash_info elf note, and adds the new field in the middle of the crash_info structure, how can it not affect compatibility? -- Keir Itsuro did it that way on purpose. It maintains backwards compatibility by keeping the dom0_pfn_to_mfn_frame_list_list field as the last field in the PT_NOTE. crash doesn't know what a crash_xen_info_t structure is, but only its old and new size.
