Subject: [PATCH v3 0/3] do_numa_page(),do_huge_pmd_numa_page() fix and cleanup

Changes from v1[1] and v2(Patch 2 only)[2]
===
1. Patch 1: Separated do_numa_page() and do_huge_pmd_numa_page() fixes,
since the issues are introduced by two separate commits.

2. Patch 1: Moved migration failure branch code and called task_numa_fault()
and return immediately when migration succeedds. (per Huang, Ying)

3. Patch 2: change do_huge_pmd_numa_page() to match do_numa_page() in
terms of page table entry manipulation (per Huang, Ying)

4. Patch 1: Restructured the code (per Kefeng Wang)

5. Patch 1: Returned immediately when page table entries do not match instead
of using goto (per David Hildenbrand)
