Issues with how the GNU GPL is used for Linux (the kernel)

[Alfred M. Szmidt]

   No, the Authors clearly stated that only v2 applies for the kernel
   as a whole, again single files may be under a different license
   (GPL compatible), and so, some of them may be under a GPL version
   that allow them to be used with the future GPLv3 license.

If the GPLv2 applies to the whole kernel, then it applies to all
files, single files cannot get special treatment.  See section 2(b) of
the GPL.
