Here's a set of patches that inserts a step into the build process to make
sure that the UAPI headers can all be built together with C++ (if the
compiler being used supports C++).  All but the final patch perform fixups,
including:

Wait, why do we care?  What has recently changed to start to directly
import kernel uapi files into C++ code?

There's at least one outstanding bug due to a C++ identifier in the kernel
UAPI headers.

Are you saying you explicitly don't want people to be able to use the kernel
UAPI headers in C++?

And if userspace wants to do this, can't they do the C namespace trick
themselves when they do the import?  That must be how they are doing it
today, right?

No, because there's no such trick (except with the preprocessor).
