You must tell the compiler that the kernel headers are written in C by 
putting 'extern "C" {...}' around the #include directives. (Or the C++ 
compiler will assume that the function prototypes are to be interpreted 
as C++, which results in different symbol names and possibly even 
different calling conventions.)
