Aneesh Kumar K.V 7b868e81be powerpc/mm: Return NULL for not present hugetlb page ... We need to check whether pte is present in follow_huge_addr() and properly return NULL if mapping is not present. Also use READ_ONCE when dereferencing pte_t address. Without this patch, we may wrongly return a zero pfn page in follow_huge_addr().
