I rewrite my patch because the patch before i sent have many white space. Thanks! --- I've been debugging the abnormal operation of i2c on octeon. If a process is terminated by signal in the middle of i2c operation, next i2c read operation which is done by another process was failed. So i changed to ignore signal in the middle of i2c operation. After that the problem was not reproduced.
