hi,
 System.map consists of list of symbols with their address. Those symbols are exported by kernel and are used by other kernel modules and drivers. So, symbol exported by one module can be used by another module.

It is actually produced by nm during kernel compilation. Thus the names out there is the name of the functions and variables with the linking address.

You have the same thing on /proc/ksyms
