Pull MM updates from Andrew Morton:
"Almost all of MM here. A few things are still getting finished off,
reviewed, etc.

- Yang Shi has improved the behaviour of khugepaged collapsing of
readonly file-backed transparent hugepages.

- Johannes Weiner has arranged for zswap memory use to be tracked and
managed on a per-cgroup basis.

- Munchun Song adds a /proc knob ("hugetlb_optimize_vmemmap") for
runtime enablement of the recent huge page vmemmap optimization
feature.

- Baolin Wang contributes a series to fix some issues around hugetlb
pagetable invalidation.

- Zhenwei Pi has fixed some interactions between hwpoisoned pages and
virtualization.

- Tong Tiangen has enabled the use of the presently x86-only
page_table_check debugging feature on arm64 and riscv.

- David Vernet has done some fixup work on the memcg selftests.

- Peter Xu has taught userfaultfd to handle write protection faults
against shmem- and hugetlbfs-backed files.

- More DAMON development from SeongJae Park - adding online tuning of
the feature and support for monitoring of fixed virtual address
ranges. Also easier discovery of which monitoring operations are
available.

- Nadav Amit has done some optimization of TLB flushing during
mprotect().

- Neil Brown continues to labor away at improving our swap-over-NFS
support.

- David Hildenbrand has some fixes to anon page COWing versus
get_user_pages().

- Peng Liu fixed some errors in the core hugetlb code.

- Joao Martins has reduced the amount of memory consumed by
device-dax's compound devmaps.

- Some cleanups of the arch-specific pagemap code from Anshuman
Khandual.

- Muchun Song has found and fixed some errors in the TLB flushing of
transparent hugepages.

- Roman Gushchin has done more work on the memcg selftests.

... and, of course, many smaller fixes and cleanups. Notably, the
customary million cleanup serieses from Miaohe Lin"

mm: change huge_ptep_clear_flush() to return the original pte

Patch series "Fix CONT-PTE/PMD size hugetlb issue when unmapping or migrating", v4.

presently, migrating a hugetlb page or unmapping a poisoned hugetlb page,
we'll use ptep_clear_flush() and set_pte_at() to nuke the page table entry
and remap it, and this is incorrect for CONT-PTE or CONT-PMD size hugetlb
page, which will cause potential data consistent issue. This patch set
will change to use hugetlb related APIs to fix this issue.

Note: Mike pointed out the huge_ptep_get() will only return the one
specific value, and it would not take into account the dirty or young bits
of CONT-PTE/PMDs like the huge_ptep_get_and_clear() [1]. This
inconsistent issue is not introduced by this patch set, and this issue
will be addressed in another thread [2]. Meanwhile the uffd for hugetlb
case [3] pointed out by Gerald also needs another patch to address.

This patch (of 3):

It is incorrect to use ptep_clear_flush() to nuke a hugetlb page table
when unmapping or migrating a hugetlb page, and will change to use
huge_ptep_clear_flush() instead in the following patches.

So this is a preparation patch, which changes the huge_ptep_clear_flush()
to return the original pte to help to nuke a hugetlb page table.
