Hmm. I also get a lot of

./usr/include/drm/amdgpu_drm.h:38: userspace cannot reference
function or variable defined in the kernel
./usr/include/drm/drm.h:63: userspace cannot reference function or
variable defined in the kernel
./usr/include/drm/drm.h:699: userspace cannot reference function or
variable defined in the kernel
...

warnings with my allmodconfig build. They do seem to be due to
checkpatch not really grokking the

#if defined(__cplusplus)
extern "C" {
#endif

and thinking that's a sign of a kernel function or variable
declaration being exported to user space, but it's a bit annoying.

Is there a patch pending for this that I'm not aware of, or is it just
that nobody but me hates spurious warnings? Didn't this show up in
linux-next? And if it _did_ show up in linux-next, why was the pull
request not talking about it?
