What's the deal with this one?

The patch is doing a bunch functions on top of the ones from the commit
message.  Were you just showing a snippet of what the actual set of
warnings is?

Also, fwiw, it would be nice to have actual words in the changelog, even
for these maddeningly repetitive series.  Even something like:

	Xen has a bunch of these because of how the paravirt code uses
	inline assembly.
