    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,
