Added three new test cases to the migration tests: 1. Shared anon THP migration test This test will mmap shared anon memory, madvise it to MADV_HUGEPAGE, then do migration entry testing. One thread will move pages back and forth between nodes whilst other threads try and access them. 2. Private anon hugetlb migration test This test will mmap private anon hugetlb memory and then do the migration entry testing. 3. Shared anon hugetlb migration test This test will mmap shared anon hugetlb memory and then do the migration entry testing.
