In [1] we discussed how we should deal with dual (or, more generally, multiple) licensed files. Add this to Licenses/README so it's properly documented.

+Ideally, the license terms of all files in the source tree should be +defined by such License Identifiers; in no case a file can contain +more than one such License Identifier.
I assume "one such License Identifier" here is intended to mean: a source line prefixed with the words "SPDX-License-Identifier:". However, to me "one such License Identifier" would actually refer to the "GPL-2.0+" part of the line, since that's what actually identifies the license. The other text simply introduces a list of license identifiers. That would then conflict with the rest of the patch that goes on to explicitly state that multiple licenses are allowed.
In other words, I think that text can be confusing. I think you need to add "line", "list" or "set" to the end of the sentence to make it unambiguous.
