In my understanding, hwpoison is a function which is only supported at high end servers and most of users do not use this function. Therefore, I think this functionality was better for option. On the other hand, as you say, nobody wants to touch/save poisoned pages and run into MCE, and it is desirable for users to exclude hwpoison pages automatically. I agree with you. I will post fixed patch without "-p" option. Please help to review it.
