I'm pretty sure this is unrelated to my patch, but it's a recurring
problem that we should get
to the bottom of. Olof's autobuilder has reported the same thing for
the 3.18-stable tree
but not any others (for every single file in the kernel, not sure if
this warning only
shows up for all of them, or just one module).
