Just to clarify -- crash-7.0.9 added support for printing warnings if DUMP_DH_COMPRESSED_INCOMPLETE is set in compressed kdump dumpfile headers, (and DUMP_ELF_INCOMPLETE flags in kdump ELF headers). But it will not issue any warnings w/respect to missing page strucures. You're going to file an associated DUMP_DH_EXCLUDED_VMEMMAP patch to the crash-utility mailing list if/when this makedumpfile patch gets accepted, correct?
