Most of them don't say anything, so they are "any GPL" by the author. When
do you people accept that Linus can't change the GPL, he can only add
comments of what he thinks is the case! His interpretation of the GPLv2
might be that not saying anything about the version means "v2 only", but if
he does so, he's simply wrong. He was wrong in the module case, as well,
and dropped this comment a while ago. He might drop this comment in future,
as well. In fact, anybody can drop this comment, as it's just a comment.

The kernel *as a whole* is clearly under GPLv2 only from Linus' comment,
which is in fact true, since the common subset of GPL versions from all
authors is indeed GPLv2 (by virtue of some files from Al Viro, and maybe
some other explicit GPL v2 files). The author must specify the version
himself, there simply is no other way. If you don't specify any, it's "any
version", because I can license all patches straight from the authors. The
way the GPLv2 allows you to explicitely specify "any version" is by not
saying anything about the version at all. Linus isn't in the positition to
change that unless he does a substantial change to the file, and also adds
a comment that this file is now GPLv2 only.
