[PATCH v2 0/5] HWpoison: further fixes and cleanups

[Oscar Salvador <osalvador@suse.de>]

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.
