    For automated testing it is useful to have the option to turn
    the warnings on copy_from_user() etc checks into errors:
    
     In function ‘copy_from_user’,
         inlined from ‘fd_copyin’ at drivers/block/floppy.c:3080,
         inlined from ‘fd_ioctl’ at drivers/block/floppy.c:3503:
       linux/arch/x86/include/asm/uaccess_32.h:213:
      error: call to ‘copy_from_user_overflow’ declared with attribute error:
      copy_from_user buffer size is not provably correct
