Hugetlb pages have ->index in size of the huge pages (PMD_SIZE or PUD_SIZE), not in PAGE_SIZE as other types of pages. This means we cannot user page_to_pgoff() to check whether we've got the right page for the radix-tree index. Let's introduce page_to_index() which would return radix-tree index for given page. We will be able to get rid of this once hugetlb will be switched to multi-order entries.
