Thank you for your review of my patch.
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.
