[PATCH v3 0/1] mm/memory-failure: don't allow to unpoison hw corrupted page

[zhenwei pi]

v2 -> v3:
- David pointed out that virt_to_kpte() is broken(no pmd_large() test
  on a PMD), so drop this API in this patch, walk kmap instead.

v1 -> v2:
- this change gets protected by mf_mutex
- use -EOPNOTSUPP instead of -EPERM 

v1:
- check KPTE to avoid to unpoison hardware corrupted page
