I take back my statement. It seems we have a lot of GPLv2 or later going on.

Is there a requirement that new files have to be GPL 2.0 only, not
GPL 2.0 or later?
Documentation/process/license-rules.rst says:
The license described in the COPYING file applies to the kernel source
as a whole, though individual source files can have a different license
which is required to be compatible with the GPL-2.0::
GPL-1.0+ : GNU General Public License v1.0 or later
GPL-2.0+ : GNU General Public License v2.0 or later
...
Aside from that, individual files can be provided under a dual license,
e.g. one of the compatible GPL variants and alternatively under a
permissive license like BSD, MIT etc.
