Now follow_page() is ready to handle hugetlb pages in whatever form, and
over all architectures. Switch to the generic code path.
Time to retire hugetlb_follow_page_mask(), following the previous
retirement of follow_hugetlb_page() in 4849807114b8.

Hugepd is only used in PowerPC so far on 4K page size kernels where hash
mmu is used. follow_page_mask() used to leverage hugetlb APIs to access
hugepd entries. Teach follow_page_mask() itself on hugepd.

Teach follow_pud_mask() to be able to handle normal PUD pages like hugetlb.

no_page_table() is not yet used for hugetlb code paths. Make it prepared.
The major difference here is hugetlb will return -EFAULT as long as page

From: Peter Xu
All the fast-gup functions take a tail page to operate, always need to do
page mask calculations before feeding that into record_subpages().
Merge that logic into record_subpages(), so that it will do the nth_page()
calculation.

Hugepd format for GUP is only used in PowerPC with hugetlbfs. There are

These macros can be helpful when we plan to merge hugetlb code into generic

We actually already defined HPAGE_PMD_NR for other reasons even if !THP.

Introduce a config option that will be selected as long as huge leaves are
involved in pgtable (thp or hugetlbfs). It would be useful to mark any
code with this new config that can process either hugetlb or thp pages in
any level that is higher than pte level.
