I'm afraid it may be deleted while patch-cleaning process..

Yes, I think so.  I (and Magnus) are not clean about mismatch factor for
getting 'idle_pg_table' and 'dom0->shared_info->pfn_to_mfn_frame_list_list'
from xen binary in crash is_netdump routine. 
I think appealing this terribleness may help keep ELF Core headers.
