Or at least split this series into more patches, such that each patch does only one "type" of SPDX replacement. I still think these conversions are probably fine, but some points that perhaps need an explicit explanation are: * Using GPL-2.0-only for files like chacha-neon-core.S whose file header says GPL v2, but also says GPL v2 or later. * Replacing with SPDX on files that explicitly say "DO NOT ALTER OR REMOVE COPYRIGHT NOTICES OR THIS FILE HEADER." * Using BSD-3-Clause when the license text in the file header has the copyright holder name instead of "copyright holder", thus making it not an exact word-for-word match with LICENSES/preferred/BSD-3-Clause. (It seems there are specific rules for variations that have been approved, e.g. see https://github.com/spdx/license-list-XML/blob/main/src/BSD-3-Clause.xml and https://spdx.github.io/spdx-spec/v2.2.2/license-matching-guidelines-and-templates) * Using "GPL-2.0-only OR BSD-3-Clause" for the two crct10dif-ce-core.S files. They have an unusual file header, and it could be argued that some contributions to those files were intended to be licensed under GPL-2.0-only. FWIW, I am fine with either license for my contributions to those files. - Eric
