+Subject: [PATCH 16/73] mm/hugetlb: fix warning in
+ alloc_huge_page/dequeue_huge_page_vma
+
+commit b1c12cbcd0a02527c180a862e8971e249d3b347d upstream.
+
+Stable note: Not tracked in Bugzilla. [get|put]_mems_allowed() is extremely
+        expensive and severely impacted page allocator performance. This
+        is part of a series of patches that reduce page allocator overhead.
+
+Fix a gcc warning (and bug?) introduced in cc9a6c877 ("cpuset: mm: reduce
+large amounts of memory barrier related damage v3")
+
+Local variable "page" can be uninitialized if the nodemask from vma policy
+does not intersects with nodemask from cpuset.  Even if it doesn't happens
+it is better to initialize this variable explicitly than to introduce
+a kernel oops in a weird corner case.
+
+mm/hugetlb.c: In function `alloc_huge_page':
+mm/hugetlb.c:1135:5: warning: `page' may be used uninitialized in this function
