The important bit of this patchset is patch#1, which is a fix to take off HWPoison pages off a buddy freelist since it can lead us to having HWPoison pages back in the game without no one noticing it. So fix it (we did that already for soft_offline_page [1]). The other patches are clean-ups and not that important, so if anything, consider patch#1 for inclusion.
