Subject[PATCH v4 0/7] HWpoison: further fixes and cleanups
Date
This patchset includes some fixups (patch#1,patch#2 and patch#3)
and some cleanups (patch#4-7).

Patch#1 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]).

Patch#2 is fixing a rebasing problem that made the call
to page_handle_poison from _soft_offline_page set the
wrong value for hugepage_or_freepage. [2]

Patch#3 is not really a fixup, but tries to re-handle a page
in case it was allocated under us.
