HWPOISON, hugetlb: soft offlining for hugepage
This patch extends soft offlining framework to support hugepage.
When memory corrected errors occur repeatedly on a hugepage,
we can choose to stop using it by migrating data onto another hugepage
and disabling the original (maybe half-broken) one.
ChangeLog since v4:
- branch soft_offline_page() for hugepage
ChangeLog since v3:
- remove comment about "ToDo: hugepage soft-offline"
ChangeLog since v2:
- move refcount handling into isolate_lru_page()
ChangeLog since v1:
- add double check in isolating hwpoisoned hugepage
- define free/non-free checker for hugepage
- postpone calling put_page() for hugepage in soft_offline_page()
