Same for:

Applying: hugetlb: fix copy_hugetlb_page_range() to handle 
migration/hwpoisoned entry
error: patch failed: mm/hugetlb.c:2519
error: mm/hugetlb.c: patch does not apply
Patch failed at 0018 hugetlb: fix copy_hugetlb_page_range() to handle 
migration/hwpoisoned entry

.. I'm building with the rest now.
