Is the kernel code covered by GPL-2-or-later by default or GPL-2?
IIRC Linus was not a fan of GPL-3, and my reading of the first few
paragraphs of license-rules.rst is that default is indeed just 2.0.

Could you find a reference to some document or discussion which would
support that "the same as all kernel sources" means 2-or-later, and add
it to the patch description?
