Some files have been flagged with the new LGPL-2.1-or-later identifier which replace the original LGPL-2.1+ in the SPDX license identifier specification, but the identifiers are not mentioned as valid in the LGPL-2.1 license file. Add it, together with the LGPL-2.1-only at the the license file.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
