[PATCH 0/4] HWpoison: further fixes and cleanups

[Oscar Salvador]

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 to us having HWPoison
pages back in the game and no one noticing it is handling a HWPoison page.
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.

Thanks
