Pull MM updates from Andrew Morton:
- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any
negative reports (or any positive ones, come to that).
- Also the Maple Tree from Liam Howlett. An overlapping range-based
tree for vmas. It it apparently slightly more efficient in its own
right, but is mainly targeted at enabling work to reduce mmap_lock
contention.
Liam has identified a number of other tree users in the kernel which
could be beneficially onverted to mapletrees.
Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
at [1]. This has yet to be addressed due to Liam's unfortunately
timed vacation. He is now back and we'll get this fixed up.
- Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses
clang-generated instrumentation to detect used-unintialized bugs down
to the single bit level.
KMSAN keeps finding bugs. New ones, as well as the legacy ones.
- Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
memory into THPs.
- Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to
support file/shmem-backed pages.
- userfaultfd updates from Axel Rasmussen
- zsmalloc cleanups from Alexey Romanov
- cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and
memory-failure
- Huang Ying adds enhancements to NUMA balancing memory tiering mode's
page promotion, with a new way of detecting hot pages.

The top-level platform selection is mostly meaningless these days after
almost everything is sorted below the CONFIG_ARCH_MULTIPLATFORM, with
the only exception being the 20+ year old StrongARM based machines.
Make this more consistent by removing the entire choice statement and
moving the StrongARM specific options into regular platform specific
Kconfig files.
The three platforms (footbridge, rpc and sa1100) are still mutually
exclusive and cannot coexist with other ARMv4/v5 machines, but since
there are only three of them and we will not add more, this can be
expressed using Kconfig 'depends on' statements.

Pull ARM boardfile deprecation from Arnd Bergmann:
"Over the past ten years, new machine support was based on device tree,
and an initial set of about 400 boards using ATAGS with boardfile for
booting were grandfathered in, with about half of them either removed
or converted to DT over time.
Based on the recent mailing list discussion I started, I have now
turned the findings into a set of patches that marks most board files
as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.
For the boards that are marked as unused, there are two final chances
for potential users: The removal is scheduled to take place after the
longterm stable kernel at the end of 2022, so users can stay on that
version for another few years, and if anyone still has one of these
machines and is planning to keep updating kernels beyond that version,
they can speak up now to have their boards taken off the list again.
Waiting for the LTS release also makes sure that there will be at
least one longterm kernel that contains the recent multiplatform
conversion along while still supporting all legacy boards.
The short summary of the current status is:
- The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
users and will be removed entirely.
- The mmp and davinci platforms have DT support for the important
machines and will become DT-only after this.
- s3c64xx, dove, orion5x, and pxa keep some board files to allow
those to be migrated over to DT more easily, but most board files
are getting removed now. DT support on these platforms is partially
working but requires changes to additional drivers for the other
boards.
- omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the
moment but have some boards with known users. Removing the board
files that nobody uses should make it easier to try a DT conversion
if anyone cares.
There is no explicit timeline what happens with the boards that remain
after this removal, but I expect to revisit this in the future, and
with most boards gone, there will be a good time to do a treewide
review of platform drivers that never gained DT support and have no
remaining in-tree board files"

Krzysztof Halasa has kept the cns3xxx platform working for a long time
but has moved away from working on it. The OpenWRT port was dropped in
2020, and support for the Gateworks Laguna platform never made it into
the mainline kernel, which only supports the reference design.
Further, the ARM11MPCore has an unresolved issue with instruction cache
coherency, and removing support for the remaining platforms using this
core would be the easiest solution.
Mark the entire platform as unused now, to be removed in early 2023 if
no users show up.

The iop32x platform has recently been converted to be part of
the multiplatform configuration, and it should be possible to
keep it alive for longer by making it boot from devicetree like
we did for the related ixp4xx platform.
However, it appears that no users remain at this point, so just
mark the entire platform depending on CONFIG_UNUSED_BOARD_FILES,
with the intention of removing it in early 2023.
If any users remain, please speak up now.
