git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull MM updates from Andrew Morton:
"As usual, many cleanups. The below blurbiage describes 42 patchsets.
21 of those are partially or fully cleanup work. "cleans up",
"cleanup", "maintainability", "rationalizes", etc.
I never knew the MM code was so dirty.
"mm: ksm: prevent KSM from breaking merging of new VMAs" (Lorenzo Stoakes)
addresses an issue with KSM's PR_SET_MEMORY_MERGE mode: newly
mapped VMAs were not eligible for merging with existing adjacent
VMAs.
"mm/damon: introduce DAMON_STAT for simple and practical access monitoring" (SeongJae Park)
adds a new kernel module which simplifies the setup and usage of
DAMON in production environments.
"stop passing a writeback_control to swap/shmem writeout" (Christoph Hellwig)
is a cleanup to the writeback code which removes a couple of
pointers from struct writeback_control.
"drivers/base/node.c: optimization and cleanups" (Donet Tom)
contains largely uncorrelated cleanups to the NUMA node setup and
management code.
"mm: userfaultfd: assorted fixes and cleanups" (Tal Zussman)
does some maintenance work on the userfaultfd code.
"Readahead tweaks for larger folios" (Ryan Roberts)
implements some tuneups for pagecache readahead when it is reading
into order>0 folios.
"selftests/mm: Tweaks to the cow test" (Mark Brown)
provides some cleanups and consistency improvements to the
selftests code.
"Optimize mremap() for large folios" (Dev Jain)
does that. A 37% reduction in execution time was measured in a
memset+mremap+munmap microbenchmark.
"Remove zero_user()" (Matthew Wilcox)
expunges zero_user() in favor of the more modern memzero_page().
"mm/huge_memory: vmf_insert_folio_*() and vmf_insert_pfn_pud() fixes" (David Hildenbrand)
addresses some warts which David noticed in the huge page code.
These were not known to be causing any issues at this time.
"mm/damon: use alloc_migrate_target() for DAMOS_MIGRATE_{HOT,COLD" (SeongJae Park)
provides some cleanup and consolidation work in DAMON.
"use vm_flags_t consistently" (Lorenzo Stoakes)
uses vm_flags_t in places where we were inappropriately using other
types.
"mm/memfd: Reserve hugetlb folios before allocation" (Vivek Kasireddy)
increases the reliability of large page allocation in the memfd
code.
"mm: Remove pXX_devmap page table bit and pfn_t type" (Alistair Popple)
removes several now-unneeded PFN_* flags.
"mm/damon: decouple sysfs from core" (SeongJae Park)
implememnts some cleanup and maintainability work in the DAMON
sysfs layer.
"madvise cleanup" (Lorenzo Stoakes)
does quite a lot of cleanup/maintenance work in the madvise() code.
"madvise anon_name cleanups" (Vlastimil Babka)
provides additional cleanups on top or Lorenzo's effort.
"Implement numa node notifier" (Oscar Salvador)
creates a standalone notifier for NUMA node memory state changes.
Previously these were lumped under the more general memory
on/offline notifier.
"Make MIGRATE_ISOLATE a standalone bit" (Zi Yan)
cleans up the pageblock isolation code and fixes a potential issue
which doesn't seem to cause any problems in practice.
"selftests/damon: add python and drgn based DAMON sysfs functionality tests" (SeongJae Park)
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.
"mm/migration: rework movable_ops page migration (part 1)" (David Hildenbrand)
provides cleanups and future-preparedness to the migration code.
"mm/damon: add trace events for auto-tuned monitoring intervals and DAMOS quota" (SeongJae Park)
adds some tracepoints to some DAMON auto-tuning code.
"mm/damon: fix misc bugs in DAMON modules" (SeongJae Park)
does that.
"mm/damon: misc cleanups" (SeongJae Park)
also does what it claims.
"mm: folio_pte_batch() improvements" (David Hildenbrand)
cleans up the large folio PTE batching code.
"mm/damon/vaddr: Allow interleaving in migrate_{hot,cold} actions" (SeongJae Park)
facilitates dynamic alteration of DAMON's inter-node allocation
policy.
"Remove unmap_and_put_page()" (Vishal Moola)
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.
"Some randome fixes and cleanups to swapfile" (Kemeng Shi)
does what is claims.
"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.
"__folio_split() clean up" (Zi Yan)
cleans up __folio_split()!
"Optimize mprotect() for large folios" (Dev Jain)
provides some quite large (>3x) speedups to mprotect() when dealing
with large folios.
"selftests/mm: reuse FORCE_READ to replace "asm volatile("" : "+r" (XXX));" and some cleanup" (wang lian)
does some cleanup work in the selftests code.
"tools/testing: expand mremap testing" (Lorenzo Stoakes)
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"

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Wrap datapath globals into net_aligned_data, to avoid false sharing
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container)
- Add SO_INQ and SCM_INQ support to AF_UNIX
- Add SIOCINQ support to AF_VSOCK
- Add TCP_MAXSEG sockopt to MPTCP
- Add IPv6 force_forwarding sysctl to enable forwarding per interface
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users
- Convert TCP send queue handling from tasklet to BH workque
- Improve BPF iteration over TCP sockets to see each socket exactly
once
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel
NAPI thread when threaded NAPI gets disabled. Previously thread
would stick around until ifdown due to tricky synchronization
- Allow multicast routing to take effect on locally-generated packets
- Add output interface argument for End.X in segment routing
- MCTP: add support for gateway routing, improve bind() handling
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed
- Support NUD_PERMANENT for proxy neighbor entries
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM
- Add sequence numbers to netconsole messages. Unregister
netconsole's console when all net targets are removed. Code
refactoring. Add a number of selftests
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup

Pull power management updates from Rafael Wysocki:
"As is tradition, cpufreq is the part with the largest number of
updates that include core fixes and cleanups as well as updates of
several assorted drivers, but there are also quite a few updates
related to system sleep, mostly focused on asynchronous suspend and
resume of devices and on making the integration of system suspend
and resume with runtime PM easier.
Runtime PM is also updated to allow some code duplication in drivers
to be eliminated going forward and to work more consistently overall
in some cases.
Apart from that, there are some driver core updates related to PM
domains that should help to address ordering issues with devm_ cleanup
routines relying on PM domains, some assorted devfreq updates
including core fixes and cleanups, tooling updates, and documentation
and MAINTAINERS updates.
Specifics:
- Fix two initialization ordering issues in the cpufreq core and a
governor initialization error path in it, and clean it up (Lifeng
Zheng)
- Add Granite Rapids support in no-HWP mode to the intel_pstate
cpufreq driver (Li RongQing)
- Make intel_pstate always use HWP_DESIRED_PERF when operating in the
passive mode (Rafael Wysocki)

- Fix minimum performance state label error in the amd-pstate driver
documentation (Shouye Liu)
- Add the CPUFREQ_GOV_STRICT_TARGET flag to the userspace cpufreq
governor and explain HW coordination influence on it in the
documentation (Shashank Balaji)
- Fix opencoded for_each_cpu() in idle_state_valid() in the DT
cpuidle driver (Yury Norov)
- Remove info about non-existing QoS interfaces from the PM QoS
documentation (Ulf Hansson)
- Use c_* types via kernel prelude in Rust for OPP (Abhinav Ananthu)
- Add HiSilicon uncore frequency scaling driver to devfreq (Jie Zhan)
- Allow devfreq drivers to add custom sysfs ABIs (Jie Zhan)
- Simplify the sun8i-a33-mbus devfreq driver by using more devm
functions (Uwe Kleine-König)
- Fix an index typo in trans_stat() in devfreq (Chanwoo Choi)
- Check devfreq governor before using governor->name (Lifeng Zheng)
- Remove a redundant devfreq_get_freq_range() call from
devfreq_add_device() (Lifeng Zheng)
- Limit max_freq with scaling_min_freq in devfreq (Lifeng Zheng)
- Replace sscanf() with kstrtoul() in set_freq_store() (Lifeng Zheng)
- Extend the asynchronous suspend and resume of devices to handle
suppliers like parents and consumers like children (Rafael Wysocki)

DPM_FLAG_SMART_SUSPEND flag and allow PCI drivers and drivers that
collaborate with the general ACPI PM domain to set it (Rafael
Wysocki)
- Add kernel parameter to disable asynchronous suspend/resume of
devices (Tudor Ambarus)
- Drop redundant might_sleep() calls from some functions in the
device suspend/resume core code (Zhongqiu Han)
- Fix the handling of monitors connected right before waking up the
system from sleep (tuhaowen)

- Rearrange suspend/resume error handling in the core device suspend
and resume code (Rafael Wysocki)
- Fix up white space that does not follow coding style in the
hibernation core code (Darshan Rathod)
- Document return values of suspend-related API functions in the
runtime PM framework (Sakari Ailus)
- Mark last busy stamp in multiple autosuspend-related functions in
the runtime PM framework and update its documentation (Sakari
Ailus)

Thanks to the meta buffer infrastructure, metadata-compressed inodes are
just read from the metabox inode instead of the blockdevice (or backing
file) inode.
The same is true for shared extended attributes.
When metadata compression is enabled, inode numbers are divided from
on-disk NIDs because of non-LTS 32-bit application compatibility.

Update the IIO ABI documentation to reflect the actual usage of channels
with I and Q modifiers. These are currently only used in a few drivers:
frequency/admv1013 (kernel v5.17):
- in_altvoltageY-altvoltageZ_i_calibphase
- in_altvoltageY-altvoltageZ_q_calibphase
- in_altvoltageY_i_calibbias
- in_altvoltageY_q_calibbias
frequency/admv1014 (kernel v5.18):
- in_altvoltageY_i_phase
- in_altvoltageY_q_phase
- in_altvoltageY_i_offset
- in_altvoltageY_q_offset
- in_altvoltageY_i_calibscale_course
- in_altvoltageY_i_calibscale_fine
- in_altvoltageY_q_calibscale_course
- in_altvoltageY_q_calibscale_fine
frequency/adrf6780 (kernel v5.16):
- out_altvoltageY_i_phase
- out_altvoltageY_q_phase
There are no _raw or _scale attributes in use, so those are all removed.
There are no currentY attributes in use with these modifiers, so those
are also removed. All of the voltageY are changed to altvoltageY since
that is how they are actually used. None of these channels are used
with scan buffers, so all of those attributes are removed as well. And
the {in,out}_altvoltageY_{i,q}_phase attributes were missing so those
are added.
The differential channel names for admv1013 are fixed.

Add the HiSilicon uncore frequency scaling driver for Kunpeng SoCs based on
the devfreq framework. The uncore domain contains shared computing
resources, including system interconnects and L3 cache. The uncore
frequency significantly impacts the system-wide performance as well as
power consumption. This driver adds support for runtime management of
uncore frequency from kernel and userspace. The main function includes
setting and getting frequencies, changing frequency scaling policies, and
querying the list of CPUs whose performance is significantly related to
this uncore frequency domain, etc. The driver communicates with a platform
controller through an ACPI PCC mailbox to take the actual actions of
frequency scaling.

The PLPKS enabled PowerVM LPAR sysfs exposes all of the secure boot
secvars irrespective of the key management mode.
The PowerVM LPAR supports static and dynamic key management for secure
boot. The key management option can be updated in the management
console. The secvars PK, trustedcadb, and moduledb can be consumed both
in the static and dynamic key management modes for the loading of signed
third-party kernel modules. However, other secvars i.e. KEK, grubdb,
grubdbx, sbat, db and dbx, which are used to verify the grub and kernel
images, are consumed only in the dynamic key management mode.
Expose only PK, trustedcadb, and moduledb in the static key management
mode.

On a PLPKS enabled PowerVM LPAR, the secvar format property for static
key management is misrepresented as "ibm,plpks-sb-unknown", creating
reason for confusion.
Static key management mode uses fixed, built-in keys. Dynamic key
management mode allows keys to be updated in production to handle
security updates without firmware rebuilds.
Define a function named plpks_get_sb_keymgmt_mode() to retrieve the
key management mode based on the existence of the SB_VERSION property
in the firmware.
Set the secvar format property to either "ibm,plpks-sb-v<version>" or
"ibm,plpks-sb-v0" based on the key management mode, and return the
length of the secvar format property.

Pull CPU speculation fixes from Borislav Petkov:
"Add the mitigation logic for Transient Scheduler Attacks (TSA)
TSA are new aspeculative side channel attacks related to the execution
timing of instructions under specific microarchitectural conditions.
In some cases, an attacker may be able to use this timing information
to infer data from other contexts, resulting in information leakage.
Add the usual controls of the mitigation and integrate it into the
existing speculation bugs infrastructure in the kernel"
* tag 'tsa_x86_bugs_for_6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/process: Move the buffer clearing before MONITOR
x86/microcode/AMD: Add TSA microcode SHAs
KVM: SVM: Advertise TSA CPUID bits to guests
x86/bugs: Add a Transient Scheduler Attacks mitigation
x86/bugs: Rename MDS machinery to something more generic

This driver has long outlived it's utility, and it's broken and unloved.
The main use case for this was direct mount with UDF of cd-rw drives
that required 32kb packets. It would collect writes into that size and
write them out in multiples of that. That's not a common use case
anymore, the world has moved on from those kinds of media. To make
matters worse, it's actively breaking setups where it's not even
required or useful.

Pull power management fixes from Rafael Wysocki:
"These address system suspend failures under memory pressure in some
configurations, fix up RAPL handling on platforms where PL1 cannot be
disabled, and fix a documentation typo:
- Prevent the Intel RAPL power capping driver from allowing PL1 to be
exceeded by mistake on systems when PL1 cannot be disabled (Zhang
Rui)
- Fix a typo in the ABI documentation (Sumanth Gavini)
- Allow swap to be used a bit longer during system suspend and
hibernation to avoid suspend failures under memory pressure (Mario
Limonciello)"
