One other thing that occurred to me is that documentation files, too,
are copyrightable and should have license identifiers.  So maybe the
documentation on these identifiers should set a good example :)  The RST
version would be:

	.. SPDX-License-Identifier: GPL-2.0

I'll try to find some time to start fixing up Documentation/ in general.
