adds additional drgn- and python-based DAMON selftests which are
more comprehensive than the existing selftest suite.

"Misc rework on hugetlb faulting path" (Oscar Salvador)
fixes a rather obscure deadlock in the hugetlb fault code and
follows that fix with a series of cleanups.

"cma: factor out allocation logic from __cma_declare_contiguous_nid" (Mike Rapoport)
rationalizes and cleans up the highmem-specific code in the CMA
allocator.

provides a couple of page->folio conversions.

"mm: per-node proactive reclaim" (Davidlohr Bueso)
implements a per-node control of proactive reclaim - beyond the
current memcg-based implementation.

"mm/damon: remove damon_callback" (SeongJae Park)
replaces the damon_callback interface with a more general and
powerful damon_call()+damos_walk() interface.

"mm/mremap: permit mremap() move of multiple VMAs" (Lorenzo Stoakes)
implements a number of mremap cleanups (of course) in preparation
for adding new mremap() functionality: newly permit the remapping
of multiple VMAs when the user is specifying MREMAP_FIXED. It still
excludes some specialized situations where this cannot be performed
reliably.

"drop hugetlb_free_pgd_range()" (Anthony Yznaga)
switches some sparc hugetlb code over to the generic version and
removes the thus-unneeded hugetlb_free_pgd_range().

"mm/damon/sysfs: support periodic and automated stats update" (SeongJae Park)
augments the present userspace-requested update of DAMON sysfs
monitoring files. Automatic update is now provided, along with a
tunable to control the update interval.

"mm: introduce snapshot_page" (Luiz Capitulino and David Hildenbrand)
provides (and uses) a means by which debug-style functions can grab
a copy of a pageframe and inspect it locklessly without tripping
over the races inherent in operating on the live pageframe
directly.

"use per-vma locks for /proc/pid/maps reads" (Suren Baghdasaryan)
addresses the large contention issues which can be triggered by
reads from that procfs file. Latencies are reduced by more than
half in some situations. The series also introduces several new
selftests for the /proc/pid/maps interface.

extends the mremap() selftest in several ways, including adding
more checking of Lorenzo's recently added "permit mremap() move of
multiple VMAs" feature.

"selftests/damon/sysfs.py: test all parameters" (SeongJae Park)
extends the DAMON sysfs interface selftest so that it tests all
possible user-requested parameters. Rather than the present minimal
subset"

mm/damon: introduce DAMON_STAT module

DAMON-based access monitoring is not simple due to required DAMON

mm/damon: introduce DAMON_STAT module

Patch series "mm/damon: introduce DAMON_STAT for simple and practical
access monitoring", v2.

DAMON-based access monitoring is not simple due to required DAMON control
and results visualizations. Introduce a static kernel module for making
it simple. The module can be enabled without manual setup and provides
access pattern metrics that easy to fetch and understand the practical
access pattern information, namely estimated memory bandwidth and memory
idle time percentiles.

Background and Problems
=======================

DAMON can be used for monitoring data access patterns of the system and
workloads. Specifically, users can start DAMON to monitor access events
on specific address space with fine controls including address ranges to
monitor and time intervals between samplings and aggregations. The
resulting access information snapshot contains access frequency
(nr_accesses) and how long the frequency was kept (age) for each byte.

The monitoring usage is not simple and practical enough for production
usage. Users should first start DAMON with a number of parameters, and
wait until DAMON's monitoring results capture a reasonable amount of the
time data (age). In production, such manual start and wait is impractical
to capture useful information from a high number of machines in a timely
manner.

The monitoring result is also too detailed to be used on production
environments. The raw results are hard to be aggregated and/or compared
for production environments having a large scale of time, space and
machines fleet.

Users have to implement and use their own automation of DAMON control and
results processing. It is repetitive and challenging since there is no
good reference or guideline for such automation.

Solution: DAMON_STAT
====================

Implement such automation in kernel space as a static kernel module,
namely DAMON_STAT. It can be enabled at build, boot, or run time via its
build configuration or module parameter. It monitors the entire physical
address space with monitoring intervals that auto-tuned for a reasonable
amount of access observations and minimum overhead. It converts the raw
monitoring results into simpler metrics that can easily be aggregated and
compared, namely estimated memory bandwidth and idle time percentiles.

Understanding of the metrics and the user interface of DAMON_STAT is
essential. Refer to the commit messages of the second and the third
patches of this patch series for more details about the metrics. For the
user interface, the standard module parameters system is used. Refer to
the fourth patch of this patch series for details of the user interface.

Discussions
===========

The module aims to be useful on production environments constructed with a
large number of machines that run a long time. The auto-tuned monitoring
intervals ensure a reasonable quality of the outputs. The auto-tuning
also ensures its overhead be reasonable and low enough to be enabled
always on the production. The simplified monitoring results metrics can
be useful for showing both coldness (idle time percentiles) and hotness
(memory bandwidth) of the system's access pattern. We expect the
information can be useful for assessing system memory utilization and
inspiring optimizations or investigations on both kernel and user space
memory management logics for large scale fleets.

We hence expect the module is good enough to be just used in most
environments. For special cases that require a custom access monitoring
automation, users will still benefit by using DAMON_STAT as a reference or
a guideline for their specialized automation.


This patch (of 4):

To use DAMON for monitoring access patterns of the system, users should
manually start DAMON via DAMON sysfs ABI with a number of parameters for
specifying the monitoring target address space, address ranges, and
monitoring intervals. After that, users should also wait until desired
amount of time data is captured into DAMON's monitoring results. It is
bothersome and take a long time to be practical for access monitoring on
large fleet level production environments.

For access-aware system operations use cases like proactive cold memory
reclamation, similar problems existed. We we solved those by introducing
dedicated static kernel modules such as DAMON_RECLAIM.

Implement such static kernel module for access monitoring, namely
DAMON_STAT. It monitors the entire physical address space with auto-tuned
monitoring intervals. The auto-tuning is set to capture 4 % of observable
access events in each snapshot while keeping the sampling intervals 5
milliseconds in minimum and 10 seconds in maximum. From a few production
environments, we confirmed this setup provides high quality monitoring
results with minimum overheads. The module therefore receives only one
user input, whether to enable or disable it. It can be set on build or
boot time via build configuration or kernel boot command line. It can
also be overridden at runtime.

Note that this commit only implements the DAMON control part of the
module. Users could get the monitoring results via damon:damon_aggregated
tracepoint, but that's of course not the recommended way. Following
commits will implement convenient and optimized ways for serving the
monitoring results to users.

Merge branch 'for-6.15/amd_sfh' into for-linus

From: Mario Limonciello <mario.limonciello@amd.com>

Some platforms include a human presence detection (HPD) sensor. When
enabled and a user is detected a wake event will be emitted from the
sensor fusion hub that software can react to.

Example use cases are "wake from suspend on approach" or to "lock
when leaving".

This is currently enabled by default on supported systems, but users
can't control it. This essentially means that wake on approach is
enabled which is a really surprising behavior to users that don't
expect it.

Instead of defaulting to enabled add a sysfs knob that users can
use to enable the feature if desirable and set it to disabled by
default.
