MODULE_LICENSE() has nothing to do with the SCO case.

As the name already indicates it is only for modules (it doesn't make 
sense in built-in code) for showing that a module has a licence that is 
compatible with the GPL (all other modules are legally somewhere between 
fishy and illegal).

The toplevel COPYING file of the kernel sources contains the exact 
licence text for all files (including binfmt_som.c) in the kernel.

Even if the wording suggested by the FSF is not used in all files it's 
clear that the kernel is under the GPLv2, and there isn't any serious 
doubt that if a file like binfmt_som.c was not under a GPLv2 compatible 
licence but built into a GPLv2'ed kernel the resulting image couldn't be 
legally distributed.

Does anyone involved with code going from HP to the Linux kernel 
seriously think that there is code for which it isn't 100% certain
that it was made available under the GPLv2?
