Thorsten Leemhuis bc41a7f364 LICENSES: Add the CC-BY-4.0 license ... 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.
