It turns out that some user-space applications use these uapi header files, so even though the only user of the interface is an old driver that was moved to staging, moving the header files causes unnecessary pain. Generally, we really don't want user space to use kernel headers directly (exactly because it causes pain when we re-organize), and instead copy them as needed.
