Pull device mapper VDO target from Mike Snitzer:
"Introduce the DM vdo target which provides block-level deduplication,
compression, and thin provisioning. Please see:
Documentation/admin-guide/device-mapper/vdo.rst
Documentation/admin-guide/device-mapper/vdo-design.rst
The DM vdo target handles its concurrency by pinning an IO, and
subsequent stages of handling that IO, to a particular VDO thread.
This aspect of VDO is "unique" but its overall implementation is very
tightly coupled to its mostly lockless threading model. As such, VDO
is not easily changed to use more traditional finer-grained locking
and Linux workqueues. Please see the "Zones and Threading" section of
vdo-design.rst
The DM vdo target has been used in production for many years but has
seen significant changes over the past ~6 years to prepare it for
upstream inclusion. The codebase is still large but it is isolated to
drivers/md/dm-vdo/ and has been made considerably more approachable
and maintainable.
Matt Sakai has been added to the MAINTAINERS file to reflect that he
will send VDO changes upstream through the DM subsystem maintainers"

Pull ata updates from Niklas Cassel:
- Do not enable LPM for external ports (hotplug-capable ports or eSATA
ports), as the HBA will not be able to detect hot plug removal events
when LPM is enabled (me)
- Drop the board type board_ahci_low_power. Now when we make sure that
we won't enable LPM for external ports, we can always set the LPM
policy to CONFIG_SATA_MOBILE_LPM_POLICY for internal ports. There is
thus no longer any need for the board type board_ahci_low_power, so
it can be removed. (As before, LPM features not supported by the HBA
and/or the device will not be enabled, regardless of the LPM policy
Kconfig) (Mario Limonciello)
Note that the default CONFIG_SATA_MOBILE_LPM_POLICY value is still 0
(which will not try to enable any LPM features), however, most Linux
distributions override this and set it to 3 (Medium power with DIPM).
We intend to change the default to 3 in the coming cycles, but we
will wait a cycle or two.
- Add board type board_ahci_pcs_quirk and make all legacy Intel
platforms use it. The Intel PCS quirk was being applied to basically
all Intel platforms, which caused some issues (the device failing to
come back after a reset), when being applied to newer Intel platforms
where it shouldn't have been applied.
New platforms can be added using board type board_ahci, which will
not have the quirk applied (me)
- Rename board_ahci_nosntf to board_ahci_pcs_quirk_no_sntf to more
clearly highlight that it applies two different quirks (me)
- Modify the ahci_broken_devslp() quirk to be implemented like all the
other quirks (i.e. define a board type for the quirk) (me)
- Drop unused board_ahci_noncq board type (me)
- Rename board_ahci_nomsi to board_ahci_no_msi to match the other board
types (me)
- Make pata_parport_bus_type const (Ricardo B. Marliere)
- Remove at91 compact flash device tree binding. (The binding is not
used by any driver.) (from Hari Prasath Gujulan Elango)
- Convert MediaTek device tree binding to json-schema (Rafał Miłecki)
- At boot, print the number of implemented ports, instead of printing
the maximum number of ports supported by the HBA silicon (me)

This reverts commit 50e3ed0f93f4f62ed2aa83de5db6cb84ecdd5707.
The SCTLR_EL1.WXN control forces execute-never when a page has write
permissions. While the idea of hardening such write/exec combinations is
good, with permissions indirection enabled (FEAT_PIE) this control
becomes RES0. FEAT_PIE introduces a slightly different form of WXN which
only has an effect when the base permission is RWX and the write is
toggled by the permission overlay (FEAT_POE, not yet supported by the
arm64 kernel). Revert the patch for now.

Pull printk updates from Petr Mladek:
"Improve the behavior during panic. The issues were found when testing
the ongoing changes introducing atomic consoles and printk kthreads:
- pr_flush() has to wait for the last reserved record instead of the
last finalized one. Note that records are finalized in random order
when generated by more CPUs in parallel.
- Ignore non-finalized records during panic(). Messages printed on
panic-CPU are always finalized. Messages printed by other CPUs
might never be finalized when the CPUs get stopped.
- Block new printk() calls on non-panic CPUs completely. Backtraces
are printed before entering the panic mode. Later messages would
just mess information printed by the panic CPU.
- Do not take console_lock in console_flush_on_panic() at all. The
original code did try_lock()/console_unlock(). The unlock part
might cause a deadlock when panic() happened in a scheduler code.

Yes, yes, I know the slab people were planning on going slow and letting
every subsystem fight this thing on their own. But let's just rip off
the band-aid and get it over and done with. I don't want to see a
number of unnecessary pull requests just to get rid of a flag that no
longer has any meaning.
This was mainly done with a couple of 'sed' scripts and then some manual
cleanup of the end result.

git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
- Freelist loading optimization (Chengming Zhou)
When the per-cpu slab is depleted and a new one loaded from the cpu
partial list, optimize the loading to avoid an irq enable/disable
cycle. This results in a 3.5% performance improvement on the "perf
bench sched messaging" test.
- Kernel boot parameters cleanup after SLAB removal (Xiongwei Song)
Due to two different main slab implementations we've had boot
parameters prefixed either slab_ and slub_ with some later becoming
an alias as both implementations gained the same functionality (i.e.
slab_nomerge vs slub_nomerge). In order to eventually get rid of the
implementation-specific names, the canonical and documented
parameters are now all prefixed slab_ and the slub_ variants become
deprecated but still working aliases.
- SLAB_ kmem_cache creation flags cleanup (Vlastimil Babka)
The flags had hardcoded #define values which became tedious and
error-prone when adding new ones. Assign the values via an enum that
takes care of providing unique bit numbers. Also deprecate
SLAB_MEM_SPREAD which was only used by SLAB, so it's a no-op since
SLAB removal. Assign it an explicit zero value. The removals of the
flag usage are handled independently in the respective subsystems,
with a final removal of any leftover usage planned for the next
release.
- Misc cleanups and fixes (Chengming Zhou, Xiaolei Wang, Zheng Yejian)
Includes removal of unused code or function parameters and a fix of a
memleak.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm
Pull lsm updates from Paul Moore:
- Promote IMA/EVM to a proper LSM
This is the bulk of the diffstat, and the source of all the changes
in the VFS code. Prior to the start of the LSM stacking work it was
important that IMA/EVM were separate from the rest of the LSMs,
complete with their own hooks, infrastructure, etc. as it was the
only way to enable IMA/EVM at the same time as a LSM.
However, now that the bulk of the LSM infrastructure supports
multiple simultaneous LSMs, we can simplify things greatly by
bringing IMA/EVM into the LSM infrastructure as proper LSMs. This is
something I've wanted to see happen for quite some time and Roberto
was kind enough to put in the work to make it happen.
- Use the LSM hook default values to simplify the call_int_hook() macro
Previously the call_int_hook() macro required callers to supply a
default return value, despite a default value being specified when
the LSM hook was defined.
This simplifies the macro by using the defined default return value
which makes life easier for callers and should also reduce the number
of return value bugs in the future (we've had a few pop up recently,
hence this work).
- Use the KMEM_CACHE() macro instead of kmem_cache_create()
The guidance appears to be to use the KMEM_CACHE() macro when
possible and there is no reason why we can't use the macro, so let's
use it.
- Fix a number of comment typos in the LSM hook comment blocks
Not much to say here, we fixed some questionable grammar decisions in
the LSM hook comment blocks.

Pull selinux updates from Paul Moore:
"Really only a few notable changes:
- Continue the coding style/formatting fixup work
This is the bulk of the diffstat in this pull request, with the
focus this time around being the security/selinux/ss directory.
We've only got a couple of files left to cleanup and once we're
done with that we can start enabling some automatic style
verfication and introduce tooling to help new folks format their
code correctly.
- Don't restrict xattr copy-up when SELinux policy is not loaded
This helps systems that use overlayfs, or similar filesystems,
preserve their SELinux labels during early boot when the SELinux
policy has yet to be loaded.
- Reduce the work we do during inode initialization time
This isn't likely to show up in any benchmark results, but we
removed an unnecessary SELinux object class lookup/calculation

- Correct the return values in selinux_socket_getpeersec_dgram()
We had some inconsistencies with respect to our return values
across selinux_socket_getpeersec_dgram() and
selinux_socket_getpeersec_stream().
This provides a more uniform set of error codes across the two
functions and should help make it easier for users to identify
the source of a failure"

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Large effort by Eric to lower rtnl_lock pressure and remove locks:
- Make commonly used parts of rtnetlink (address, route dumps
etc) lockless, protected by RCU instead of rtnl_lock.
- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core instead
of once for each driver / callback.
- Remove locks / serialization in the socket diag interface.
- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
- Remove the dev_base_lock, depend on RCU where necessary.
- Support busy polling on a per-epoll context basis. Poll length and
budget parameters can be set independently of system defaults.
- Introduce struct net_hotdata, to make sure read-mostly global
config variables fit in as few cache lines as possible.
- Add optional per-nexthop statistics to ease monitoring / debug of
ECMP imbalance problems.
- Support TCP_NOTSENT_LOWAT in MPTCP.
- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.
- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.
- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.
- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.
- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for use
on fastpaths).
- Speed up scanning for expired routes by keeping a dedicated list.
- Speed up "generic" XDP by trying harder to avoid large allocations.
- Support attaching arbitrary metadata to netconsole messages.
Things we sprinkled into general kernel code:
- Enforce VM_IOREMAP flag and range in ioremap_page_range and
introduce VM_SPARSE kind and vm_area_[un]map_pages (used by
bpf_arena).
- Rework selftest harness to enable the use of the full range of ksft
exit code (pass, fail, skip, xfail, xpass).
Netfilter:
- Allow userspace to define a table that is exclusively owned by a
daemon (via netlink socket aliveness) without auto-removing this
table when the userspace program exits. Such table gets marked as
orphaned and a restarting management daemon can re-attach/regain
ownership.
- Speed up element insertions to nftables' concatenated-ranges set
type. Compact a few related data structures.
BPF:
- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.
- Introduce bpf_arena which is sparse shared memory region between
BPF program and user space where structures inside the arena can
have pointers to other areas of the arena, and pointers work
seamlessly for both user-space programs and BPF programs.
- Introduce may_goto instruction that is a contract between the
verifier and the program. The verifier allows the program to loop
assuming it's behaving well, but reserves the right to terminate
it.
- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.
- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops
type.
- Add support for retrieval of cookies for perf/kprobe multi links.
- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF
firewalls.
- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF
objects.
Wireless:
- Add SPP (signaling and payload protected) AMSDU support.
- Support wider bandwidth OFDMA, as required for EHT operation.
Driver API:
- Major overhaul of the Energy Efficient Ethernet internals to
support new link modes (2.5GE, 5GE), share more code between
drivers (especially those using phylib), and encourage more
uniform behavior. Convert and clean up drivers.
- Define an API for querying per netdev queue statistics from
drivers.
- IPSec: account in global stats for fully offloaded sessions.
- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.
- Enable Rx hashing (RSS) on GTP protocol fields.
Misc:
- Improvements and refactoring all over networking selftests.
- Create uniform module aliases for TC classifiers, actions, and
packet schedulers to simplify creating modprobe policies.
- Address all missing MODULE_DESCRIPTION() warnings in networking.
- Extend the Netlink descriptions in YAML to cover message
encapsulation or "Netlink polymorphism", where interpretation of
nested attributes depends on link type, classifier type or some
other "class type".

Patch series "selftests/mm: Improve Hugepage Test Handling in MM
Selftests", v2.
This series addresses issues related to hugepage requirements in the MM
selftests, ensuring tests are skipped rather than failing when the
necessary hugepage count is not met.
This adjustment allows for a more graceful handling for systems with
insufficient hugepages, preventing unnecessary test failures and improving
the overall robustness of the test suite.
This patch (of 3):
On systems that have large core counts and large page sizes, but limited
memory, the userfaultfd test hugepage requirement is too large.
Exiting early due to missing one test's requirements is a rather
aggressive strategy, and prevents a lot of other tests from running.
Remove the early exit to prevent this.

A folio can only be split into lower orders.

passed via debugfs into split_huge_page_to_list_to_order().
Check new_order to make sure it is smaller than input folio order.

With cache_trim_mode on, reclaim logic doesn't bother reclaiming anon
pages. However, it should be more careful to use the mode because it's
going to prevent anon pages from being reclaimed even if there are a huge
number of anon pages that are cold and should be reclaimed. Even worse,
that leads kswapd_failures to reach MAX_RECLAIM_RETRIES and stopping
kswapd from functioning until direct reclaim eventually works to resume
kswapd.
So kswapd needs to retry its scan priority loop with cache_trim_mode off
again if the mode doesn't work for reclaim.
The problematic behavior can be reproduced by:
CONFIG_NUMA_BALANCING enabled
sysctl_numa_balancing_mode set to NUMA_BALANCING_MEMORY_TIERING
numa node0 (8GB local memory, 16 CPUs)
numa node1 (8GB slow tier memory, no CPUs)
Sequence:
1) echo 3 > /proc/sys/vm/drop_caches
2) To emulate the system with full of cold memory in local DRAM, run
the following dummy program and never touch the region:
mmap(0, 8 * 1024 * 1024 * 1024, PROT_READ | PROT_WRITE,
MAP_ANONYMOUS | MAP_PRIVATE | MAP_POPULATE, -1, 0);
3) Run any memory intensive work e.g. XSBench.
4) Check if numa balancing is working e.i. promotion/demotion.
5) Iterate 1) ~ 4) until numa balancing stops.
With this, you could see that promotion/demotion are not working because
kswapd has stopped due to ->kswapd_failures >= MAX_RECLAIM_RETRIES.

Users of UFFDIO_CONTINUE may reasonably assume that a write memory barrier
is included as part of UFFDIO_CONTINUE. That is, a user may believe that
all writes it has done to a page that it is now UFFDIO_CONTINUE'ing are
guaranteed to be visible to anyone subsequently reading the page through
the newly mapped virtual memory region.
Today, such a user happens to be correct. mmget_not_zero(), for example,
is called as part of UFFDIO_CONTINUE (and comes before any PTE updates),
and it implicitly gives us a write barrier.
To be resilient against future changes, include an explicit smp_wmb().
While we're at it, optimize the smp_wmb() that is already incidentally
present for the HugeTLB case.
Merely making a syscall does not generally imply the memory ordering
constraints that we need (including on x86).

My recent change to put_pages_list() dereferences folio->lru.next after
returning the folio to the page allocator. Usually this is now on the pcp
list with other free folios, so we try to free an already-free folio.
This only happens with lists that have more than 15 entries, so it wasn't
immediately discovered. Revert to using list_for_each_safe() so we
dereference lru.next before disposing of the folio.

When freeing a large folio, we must remove it from the deferred split list
before we uncharge it as each memcg has its own deferred split list (with
associated lock) and removing a folio from the deferred split list while
holding the wrong lock will corrupt that list and cause various related
problems.

Pull btrfs updates from David Sterba:
"Mostly stabilization, refactoring and cleanup changes. There rest are
minor performance optimizations due to caching or lock contention
reduction and a few notable fixes.
Performance improvements:
- minor speedup in logging when repeatedly allocated structure is
preallocated only once, improves latency and decreases lock
contention
- minor throughput increase (+6%), reduced lock contention after
clearing delayed allocation bits, applies to several common
workload types
- skip full quota rescan if a new relation is added in the same
transaction
Fixes:
- zstd fix for inline compressed file in subpage mode, updated
version from the 6.8 time
- proper qgroup inheritance ioctl parameter validation
- more fiemap followup fixes after reduced locking done in 6.8:
- fix race when detecting delalloc ranges
Core changes:
- more debugging code:
- added assertions for a very rare crash in raid56 calculation
- tree-checker dumps page state to give more insights into
possible reference counting issues
- add checksum calculation offloading sysfs knob, for now enabled
under DEBUG only to determine a good heuristic for deciding the
offload or synchronous, depends on various factors (block group
profile, device speed) and is not as clear as initially thought
(checksum type)
- error handling improvements, added assertions
- more page to folio conversion (defrag, truncate), cached size and
shift
- preparation for more fine grained locking of sectors in subpage
mode
- cleanups and refactoring:
- include cleanups, forward declarations
- pointer-to-structure helpers
- redundant argument removals
- removed unused code
- slab cache updates, last use of SLAB_MEM_SPREAD removed"

Pull SoC device tree updates from Arnd Bergmann:
"There is very little going on with new SoC support this time, all the
new chips are variations of others that we already support, and they
are all based on ARMv8 cores:
- Mediatek MT7981B (Filogic 820) and MT7988A (Filogic 880) are
networking SoCs designed to be used in wireless routers, similar to
the already supported MT7986A (Filogic 830).
- NXP i.MX8DXP is a variant of i.MX8QXP, with two CPU cores less.
These are used in many embedded and industrial applications.
- Renesas R8A779G2 (R-Car V4H ES2.0) and R8A779H0 (R-Car V4M) are
automotive SoCs.
- TI J722S is another automotive variant of its K3 family, related to
the AM62 series.
There are a total of 7 new arm32 machines and 45 arm64 ones, including
- Two Android phones based on the old Tegra30 chip
- Two machines using Cortex-A53 SoCs from Allwinner, a mini PC and a
SoM development board
- A set-top box using Amlogic Meson G12A S905X2
- Eight embedded board using NXP i.MX6/8/9
- Three machines using Mediatek network router chips
- Ten Chromebooks, all based on Mediatek MT8186
- One development board based on Mediatek MT8395 (Genio 1200)
- Seven tablets and phones based on Qualcomm SoCs, most of them from
Samsung.
- A third development board for Qualcomm SM8550 (Snapdragon 8 Gen 2)
- Three variants of the "White Hawk" board for Renesas automotive
SoCs
- Ten Rockchips RK35xx based machines, including NAS, Tablet, Game
console and industrial form factors.
- Three evaluation boards for TI K3 based SoCs

hardware, cleanups, and dtc compile time fixes. One notable change is
the inclusion of PowerVR SGX GPU nodes on TI SoCs"
