2021-07-15LICENSES/dual/CC-BY-4.0: Git rid of "smart quotes"Nishanth Menon1-1/+1
A couple of exotic quote characters came in with this license text; they can confuse software that is not expecting non-ASCII text. Switch to normal quotes here, with no changes to the actual license text.

2020-12-08LICENSES: Add the CC-BY-4.0 licenseThorsten Leemhuis1-0/+410
Add the full text of the CC-BY-4.0 license to the kernel tree as well as the required tags for reference and tooling. The license text was copied directly from the following url, but for clarification a 'Creative Commons' was added before 'Attribution 4.0 International' in the first line: https://creativecommons.org/licenses/by/4.0/legalcode.txt CC-BY-4.0 is GPLv2 compatible, but when for example used for the kernel's documentation it can easily happen that sphinx during processing combines it with text or code from files using a more restrictive license[1]. This bears pitfalls, hence point that risk out and suggest to only use this license in combination with the GPLv2.

2019-05-03LICENSES: Clearly mark dual license only licensesChristoph Hellwig3-0/+1037
Just like the CDDL the Apache license and the MPL must only be used as a choice in additional to an GPL2 compatible license. Copy over the boilerplate from the CDDL file to the other two after fixing it up to make it clear the licenses need to be GPL2 compatible, not just the more generic GPL compatible. For example the Apache 2 license is GPL3 compatible, but that doesn't matter for the kernel. Also move these licenses to a separate directory and document the rules in license-rules.rst.
