Linus Torvalds e4b4bfaa50 SPDX patches for 7.2-rc1
Here is a "big" set of SPDX-like patches for 7.2-rc1.  It is the
 addition of the ability for the kernel build process to generate a
 Software Bill of Materials (SBOM) in the SPDX format, that matches up
 exactly with just the files that are actually built for the specific
 kernel image generated.
 
 To generate a sbom, after the kernel has been built, just do:
 	make sbom
 and marvel at the JSON file that is generated...
 
 This is needed by users for environments in which a SBOM is required
 (medical, automotive, anything shipped in the EU, etc.) and cuts down by
 a massive size the "naive" SBOM solution that many vendors have done by
 just including _all_ of the kernel files in the resulting document.
 
 This result is still a giant JSON file, that I am told parses properly,
 so we just have to trust that it is properly inclusive as attempting to
 parse that thing by hand is impossible.
 
 The scripts here are self-contained python scripts, no additional
 libraries or tools to create the SBOM are needed, which is important for
 many build systems.  Overall it's just a bit over 4000 lines of "simple"
 python code, the most complex part is the regex matching lines, but
 those are nothing compared to what we maintain in scripts/checkpatch.pl
 today...
 
 The various parts where the tool touches the kbuild subsystem have been
 acked by the kbuild maintainer, so all should be good here.
 
 All of these patches have been in linux-next for weeks with no reported
 problems.
