This is the update of "active page flag for hugetlb" patch [*1]. The main change is patch 2/3, which fixes the race condition where concurrent call of isolate_huge_page() causes kernel panic. Patch 1/3 just mentions and "fixes" a potential problem, no behavioral change. Patch 3/3 is a cleanup, reduces lines of code.
