Provides the script: Documentation/features/scripts/features-refresh.sh which operates on the arch-support.txt files and refreshes them in place. This way [1], "[...] we soft- decouple the refreshing of the entries from the introduction of the features, while still making it all easy to keep sync and to extend."

Thomas said: There are a few bogus SPDX identifiers in various files and SPDX Identifiers used in tree or about to be used which have no corresponding License Text file in the LICENSES directory or use the new variant of the GPL-2.0[+] license identifiers which are not mentioned in the GPL-2.0 Valid-License-Identifiers: tags. There is no tool which can be used to scan the tree and also nothing which helps people who submit patches to check their stuff before submission. The following series cleans that up: - Add GPL-2.0-only and GPL-2.0-or-later identifiers to the GPL2.0 license and the Linux-syscall-note exception - Add X11, Apache-2.0, CC-BY-SA-4.0, CCDL-1.0, Linux-OpenIB license texts to the LICENSES directory along with the required documentation texts - Add a checker script which can read a single file or even a patch from the command line or does a full git tree scan [Thomas also wins some sort of special prize for including an SPDX-checking patch that complains about itself!]

The SPDX-License-Identifiers are growing in the kernel and so grow expression failures and license IDs are used which have no corresponding license text file in the LICENSES directory. Add a script which gathers information from the LICENSES directory, i.e. the various tags in the licenses and exception files and then scans either input from stdin, which it treats as a single file or if started without arguments it scans the full kernel tree. It checks whether the license expression syntax is correct and also validates whether the license identifiers used in the expressions are available in the LICENSES files. scripts/spdxcheck.py -h usage: spdxcheck.py [-h] [-m MAXLINES] [-v] [path [path ...]] SPDX expression checker positional arguments: path Check path or file.

Quite some files have been flagged with the new GPL-2.0-only and GPL-2.0-or-later identifiers which replace the original GPL-2.0 and GPL-2.0+ identifiers in the SPDX license identifier specification, but the identifiers are not mentioned as valid in the GPL-2.0 license file.
