Hi Andrew, This patch adds both symbol 'vmlist' and offset 'vm_struct.addr' to the vmcoreinfo[1] data for i386 vmalloc translation.
makedumpfile[2] needs VMALLOC_START value for distinguishing a vmalloc address or not, because it should choose suitable translation method. If applying this patch, makedumpfile will be able to take VMALLOC_START value from 'vmlist.addr'. This patch is for linux-2.6.27 and its CodingStyle have been checked by checkpatch.pl. vmcoreinfo[1]: The vmcoreinfo data has the minimum debugging information only for dump filtering. makedumpfile[2] uses it to distinguish unnecessary pages and creates a small dumpfile. makedumpfile[2]: dump filtering command https://sourceforge.net/projects/makedumpfile/ Thanks Ken'ichi Ohmichi Signed-off-by: Ken'ichi Ohmichi <[EMAIL PROTECTED]> --- --- a/kernel/kexec.c 2008-10-10 07:13:53.000000000 +0900 +++ b/kernel/kexec.c 2008-10-15 13:12:50.000000000 +0900 @@ -1371,6 +1371,7 @@ static int __init crash_save_vmcoreinfo_ VMCOREINFO_SYMBOL(node_online_map); VMCOREINFO_SYMBOL(swapper_pg_dir); VMCOREINFO_SYMBOL(_stext); + VMCOREINFO_SYMBOL(vmlist); #ifndef CONFIG_NEED_MULTIPLE_NODES VMCOREINFO_SYMBOL(mem_map); @@ -1406,6 +1407,7 @@ static int __init crash_save_vmcoreinfo_ VMCOREINFO_OFFSET(free_area, free_list); VMCOREINFO_OFFSET(list_head, next); VMCOREINFO_OFFSET(list_head, prev); + VMCOREINFO_OFFSET(vm_struct, addr); VMCOREINFO_LENGTH(zone.free_area, MAX_ORDER); VMCOREINFO_LENGTH(free_area.free_list, MIGRATE_TYPES); VMCOREINFO_NUMBER(NR_FREE_PAGES); _
