Linus, please merge this cycles's batch of MM changes.  This is almost
everything - I'll have another 5-10 patches next week.

I'm seeing a few conflicts against your present tree:

arch/arm/configs/oxnas_v6_defconfig: just remove this file

https://lkml.kernel.org/r/20230317124408.4f868a50@canb.auug.org.au

mm/mmap.c:
This is new, as a result of the patch from Vlastimil which
you just merged.  I assume the resolution is to replace the new

	vma_pgoff =3D next->vm_pgoff;

with

	vma_pgoff =3D next->vm_pgoff - pglen;

mm/slob.c: simply remove slob.c

  mm,unmap: avoid flushing TLB in batch if PTE is inaccessible (2023-04-27 =
13:42:16 -0700)

----------------------------------------------------------------
- Nick Piggin's "shoot lazy tlbs" series, to improve the peformance of
  switching from a user process to a kernel thread.

- More folio conversions from Kefeng Wang, Zhang Peng and Pankaj Raghav.

- zsmalloc performance improvements from Sergey Senozhatsky.

- Yue Zhao has found and fixed some data race issues around the
  alteration of memcg userspace tunables.

- VFS rationalizations from Christoph Hellwig:

  - removal of most of the callers of write_one_page().

  - make __filemap_get_folio()'s return value more useful

- Luis Chamberlain has changed tmpfs so it no longer requires swap
  backing.  Use `mount -o noswap'.

- Qi Zheng has made the slab shrinkers operate locklessly, providing
  some scalability benefits.

- Keith Busch has improved dmapool's performance, making part of its
  operations O(1) rather than O(n).

- Peter Xu adds the UFFD_FEATURE_WP_UNPOPULATED feature to userfaultd,
  permitting userspace to wr-protect anon memory unpopulated ptes.

- Kirill Shutemov has changed MAX_ORDER's meaning to be inclusive rather
  than exclusive, and has fixed a bunch of errors which were caused by its
  unintuitive meaning.

- Axel Rasmussen give userfaultfd the UFFDIO_CONTINUE_MODE_WP feature,
  which causes minor faults to install a write-protected pte.

- Vlastimil Babka has done some maintenance work on vma_merge():
  cleanups to the kernel code and improvements to our userspace test
  harness.

- Cleanups to do_fault_around() by Lorenzo Stoakes.

- Mike Rapoport has moved a lot of initialization code out of various
  mm/ files and into mm/mm_init.c.

- Lorenzo Stoakes removd vmf_insert_mixed_prot(), which was added for
  DRM, but DRM doesn't use it any more.

- Lorenzo has also coverted read_kcore() and vread() to use iterators
  and has thereby removed the use of bounce buffers in some cases.

- Lorenzo has also contributed further cleanups of vma_merge().

- Chaitanya Prakash provides some fixes to the mmap selftesting code.

- Matthew Wilcox changes xfs and afs so they no longer take sleeping
  locks in ->map_page(), a step towards RCUification of pagefaults.

- Suren Baghdasaryan has improved mmap_lock scalability by switching to
  per-VMA locking.

- Frederic Weisbecker has reworked the percpu cache draining so that it
  no longer causes latency glitches on cpu isolated workloads.

- Mike Rapoport cleans up and corrects the ARCH_FORCE_MAX_ORDER Kconfig
  logic.

- Liu Shixin has changed zswap's initialization so we no longer waste a
  chunk of memory if zswap is not being used.

- Yosry Ahmed has improved the performance of memcg statistics flushing.

- David Stevens has fixed several issues involving khugepaged,
  userfaultfd and shmem.

- Christoph Hellwig has provided some cleanup work to zram's IO-related
  code paths.

- David Hildenbrand has fixed up some issues in the selftest code's
  testing of our pte state changing.

- Pankaj Raghav has made page_endio() unneeded and has removed it.

- Peter Xu contributed some rationalizations of the userfaultfd
  selftests.

- Yosry Ahmed has fixed an issue around memcg's page recalim accounting.

- Chaitanya Prakash has fixed some arm-related issues in the
  selftests/mm code.

- Longlong Xia has improved the way in which KSM handles hwpoisoned
  pages.

- Peter Xu fixes a few issues with uffd-wp at fork() time.

- Stefan Roesch has changed KSM so that it may now be used on a
  per-process and per-cgroup basis.
