Oh, good point. If makedumpfile cannot distinguish the pgtable, it guesses PGTABLE_3 and creates a dumpfile. If Jay's kernel .config file has CONFIG_PGTABLE_4=y, makedumpfile misunderstands the pgtable. If it has CONFIG_PGTABLE_4=y, could you please try the attached patch ? This patch is only for debugging, and I'll investigate the cause.
