Well, uaccess_32.h has this:

extern void copy_from_user_overflow(void)
#ifdef CONFIG_DEBUG_STRICT_USER_COPY_CHECKS
__compiletime_error("copy_from_user() buffer size is not provably correct")
#else
__compiletime_warning("copy_from_user() buffer size is not provably correct"
)
#endif

and you have CONFIG_DEBUG_STRICT_USER_COPY_CHECKS=y.

ciao,
