Now that the SPDX tag is in all arch/s390/ files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording in the remaining files can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.
