Those macros are used as maplist_type in struct maplist_s (see
kl_sym.h).

SYM_MAP_FILE - stands for a symbol table loaded from a file
(usually System.map) and not associated with a kernel module.

SYM_MAP_MODULE - stands for a symbol table associated with a kernel
module. (Of course it is also loaded from a file, so the naming of
SYM_MAP_FILE is somehow misleading. Any suggestions to rename
SYM_MAP_FILE are welcome. ;-)

SYM_MAP_KSYM - stands for the symbol table contained in the dumped
kernel. Same information you get in a running Linux 2.4 using
"cat /proc/ksyms".

SYM_MAP_ANY - any kind of a symbol table (or "map file") in lkcd.

Creation of symbol tables in lkcd differs for all three types of
tables (SYM_MAP_FILE, SYM_MAP_MODULE and SYM_MAP_KSYMS). Furthermore
the output of the tables is slightly different for each type.
