This is another thing which we need to address. We should not be using
unsigned int/unsigned long/uintXX_t/etc in here, but the __uXX and __sXX
The lesson learned from other DRM developers is that using these types
simplifies the API especially when it comes to the differences between
32-bit and 64-bit machines, and compat applications.
Note that drm/drm.h is all that should need to be included - drm/drm.h
takes care of including linux/types.h when building on Linux platforms.
(note: if your compiler doesn't set __linux__ then you're probably not
using the proper compiler...)
