The full kernel is licensed under v2 of the GPL only, not "any later version".
See the second paragraph at the top of the COPYING file in the root directory
of the kernel source tree. There are differences on individual files, but
having this file allow "any later version" makes it different from much of
rest of the kernel.

Unless you have a specific reason to allow greater-than-V2 GPL licensing on this
file, you should change the licensing clause.  The following wording appears
to be pretty popular:

* This program is free software; you can redistribute it and/or modify
* it under the terms of the GNU General Public License version 2 as
* published by the Free Software Foundation.
