Yeah, I came across hwpoison-inject module when doing my re-write,
and I felt like this is begging for a clean up.

Since unpoison_memory needs some adjustments after my re-write, I will go ahead
and clean that up, otherwise it will be inconsistent.

I expect to be ready fo send the v2 by the end of this week.
