[RFC PATCH 21/24] mm/hugetlb: Merge pte to huge pmd only for gigantic page

Merge pte to huge pmd if it has ever been split. Now only support gigantic page which's vmemmap pages size is an integer multiple of PMD_SIZE. This is the simplest case to handle. Signed-off-by: Muchun Song --- include/linux/hugetlb.h | 7 +++ mm/hugetlb.c| 104
