driver core: faux: Quiet probe failures
The acpi-einj conversion to faux_device_create() leads to a noisy error
message when the error injection facility is disabled. Quiet the error as
CXL error injection via ACPI expects the module to stay loaded even if the
error injection facility is disabled.
This situation arose because CXL knows proper kernel named objects to
trigger errors against, but acpi-einj knows how to perform the error
injection. The injection mechanism is shared with non-CXL use cases. The
result is CXL now has a module dependency on einj-core.ko, and init/probe
failures are handled at runtime.
Fixes:

driver core: faux: Suppress bind attributes
faux_device_create() is almost a suitable candidate to replace
platform_driver_probe() if not for the fact that faux_device_create()
supports dynamic attach/detach of the driver.
Drop the bind attributes with the expectation that simple faux devices can
always assume that the device is permanently bound at create, and only
unbound at 'destroy'.
The acpi-einj driver depends on static bind.

Char/Misc/IIO pull request for 6.16-rc1
Here is the big char/misc/iio and other small driver subsystem pull
request for 6.16-rc1.
Overall, a lot of individual changes, but nothing major, just the normal
constant forward progress of new device support and cleanups to existing
subsystems. Highlights in here are:
- Large IIO driver updates and additions and device tree changes
- Android binder bugfixes and logfile fixes
- mhi driver updates
- comedi driver updates
- counter driver updates and additions
- coresight driver updates and additions
- echo driver removal as there are no in-kernel users of it
- nvmem driver updates
- spmi driver updates
- new amd-sbi driver "subsystem" and drivers added
- rust miscdriver binding documentation fix
- other small driver fixes and updates (uio, w1, acrn, hpet, xillybus,
cardreader drivers, fastrpc and others.)
All of these have been in linux-next for quite a while with no reported
problems.

Power management fixes for 6.16-rc1
Fix three issues introduced into device suspend/resume error paths in the PM core by some of the recent updates. First off, replace list_splice() with list_splice_init() in three places in device suspend error paths to avoid attempting to use an uninitialized list head going forward. Second, rearrange device_resume() to avoid leaking the power.is_suspended device PM flag to the next system suspend/resume cycle where it can confuse rolling back after an error or early wakeup. Finally, add synchronization to dpm_async_resume_children() to avoid resetting the async state mistakenly for devices whose resume callbacks have already been queued up for asynchronous execution in the given device resume phase, which fortunately can happen only if the preceding system suspend transition has been aborted. -----BEGIN PGP SIGNATURE----- iQFGBAABCAAwFiEEcM8Aw/RY0dgsiRUR7l+9nS/U47UFAmhB5vASHHJqd0Byand5 c29ja2kubmV0AAoJEO5fvZ0v1OO1k7IH/RyTAYq/CyilGYCk7/Sd2NgOOrlkhapV s6J3qi13aegcVX1sskJTlgR893Zh1GVIEbNH0DtQz8ExhPb+XIwCxWVIZTaDfogj q40Y7DFn7XIhIH9KkmUab0/PKGdJjxz5EnLfJCFxYjztHC7W4Vx4hnaQyysFXa3t r1hm2e2wWeVKzayFkMUblfXAHX2PSy/JoHZTy71yMDO7XpOui97gr8DsINdXgG6e yCuTQX+3S0bwxnlRL6sHMvvaXMqZZzjVz50uJojP6bQ+7TdppYVIz/y6FVMuOmDd sAoAWz0/rAukjXf3bzqPcHJLvDixBXokFkTfAyMb9a+SKoofTSvULkY= =Wj0P -----END PGP SIGNATURE----- Merge tag 'pm-6.16-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management fixes from Rafael Wysocki: "Fix three issues introduced into device suspend/resume error paths in the PM core by some of the recent updates.

- The 11 patch series "Add folio_mk_pte()" from Matthew Wilcox
simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - The 8 patch series "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - The 3 patch series "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - The 2 patch series "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction. In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - The 8 patch series "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - The 6 patch series "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments. At this time we can alter only "system call information that are used by strace system call tampering, namely, syscall number, syscall arguments, and syscall return value. This series should have been incorporated into mm.git's "non-MM" branch, but I goofed. - The 3 patch series "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl against /proc/pid/pagemap. This permits CRIU to more efficiently get at the info about guard regions. - The 2 patch series "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan implements that fix. No runtime effect is expected because validate_page_before_insert() happens to fix up this error. - The 3 patch series "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David Hildenbrand basically brings uprobe text poking into the current decade. Remove a bunch of hand-rolled implementation in favor of using more current facilities. - The 3 patch series "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman Khandual provides enhancements and generalizations to the pte dumping code. This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - The 12 patch series "Always call constructor for kernel page tables" from Kevin Brodsky "ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables". This permits the addition of more functionality such as "insert hooks to protect page tables". This change does result in various architectures performing unnecesary work, but this is fixed up where it is anticipated to occur. - The 9 patch series "Rust support for mm_struct, vm_area_struct, and mmap" from Alice Ryhl adds plumbing to permit Rust access to core MM structures. - The 3 patch series "fix incorrectly disallowed anonymous VMA merges" from Lorenzo Stoakes takes advantage of some VMA merging opportunities which we've been missing for 15 years. - The 4 patch series "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from SeongJae Park optimizes process_madvise()'s TLB flushing. Instead of flushing each address range in the provided iovec, we batch the flushing across all the iovec entries. The syscall's cost was approximately halved with a microbenchmark which was designed to load this particular operation. - The 6 patch series "Track node vacancy to reduce worst case allocation counts" from Sidhartha Kumar makes the maple tree smarter about its node preallocation. stress-ng mmap performance increased by single-digit percentages and the amount of unnecessarily preallocated memory was dramaticelly reduced. - The 3 patch series "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes a few unnecessary things which Baoquan noted when reading the code. - The 3 patch series ""Enhance sysfs handling for memory hotplug in weighted interleave" from Rakie Kim "enhances the weighted interleave policy in the memory management subsystem by improving sysfs handling, fixing memory leaks, and introducing dynamic sysfs updates for memory hotplug support". Fixes things on error paths which we are unlikely to hit. - The 7 patch series "mm/damon: auto-tune DAMOS for NUMA setups including tiered memory" from SeongJae Park introduces new DAMOS quota goal metrics which eliminate the manual tuning which is required when utilizing DAMON for memory tiering. - The 5 patch series "mm/vmalloc.c: code cleanup and improvements" from Baoquan He provides cleanups and small efficiency improvements which Baoquan found via code inspection. - The 2 patch series "vmscan: enforce mems_effective during demotion" from Gregory Price "changes reclaim to respect cpuset.mems_effective during demotion when possible". because "presently, reclaim explicitly ignores cpuset.mems_effective when demoting, which may cause the cpuset settings to violated."

In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments.

This permits CRIU to more efficiently get at the info about guard regions. - "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan implements that fix. No runtime effect is expected because validate_page_before_insert() happens to fix up this error. - "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David Hildenbrand basically brings uprobe text poking into the current decade. Remove a bunch of hand-rolled implementation in favor of using more current facilities. - "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman Khandual provides enhancements and generalizations to the pte dumping code. This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - "Always call constructor for kernel page tables" from Kevin Brodsky ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables. This permits the addition of more functionality such as "insert hooks to protect page tables". This change does result in various architectures performing unnecesary work, but this is fixed up where it is anticipated to occur. - "Rust support for mm_struct, vm_area_struct, and mmap" from Alice Ryhl adds plumbing to permit Rust access to core MM structures. - "fix incorrectly disallowed anonymous VMA merges" from Lorenzo Stoakes takes advantage of some VMA merging opportunities which we've been missing for 15 years. - "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from SeongJae Park optimizes process_madvise()'s TLB flushing. Instead of flushing each address range in the provided iovec, we batch the flushing across all the iovec entries. The syscall's cost was approximately halved with a microbenchmark which was designed to load this particular operation. - "Track node vacancy to reduce worst case allocation counts" from Sidhartha Kumar makes the maple tree smarter about its node preallocation. stress-ng mmap performance increased by single-digit percentages and the amount of unnecessarily preallocated memory was dramaticelly reduced. - "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes a few unnecessary things which Baoquan noted when reading the code. - ""Enhance sysfs handling for memory hotplug in weighted interleave" from Rakie Kim "enhances the weighted interleave policy in the memory management subsystem by improving sysfs handling, fixing memory leaks, and introducing dynamic sysfs updates for memory hotplug support".

Driver core changes for 6.16-rc1
Here are the driver core / kernfs changes for 6.16-rc1.
Not a huge number of changes this development cycle, here's the summary
of what is included in here:
- kernfs locking tweaks, pushing some global locks down into a per-fs
image lock
- rust driver core and pci device bindings added for new features.
- sysfs const work for bin_attributes. This churn should now be
completed for those types of attributes
- auxbus device creation helpers added
- fauxbus fix for creating sysfs files after the probe completed
properly
- other tiny updates for driver core things.
All of these have been in linux-next for over a week with no reported
issues.

Pull power management updates from Rafael Wysocki:
"Once again, the changes are dominated by cpufreq updates, but this
time the majority of them are cpufreq core changes, mostly related to
the introduction of policy locking guards and __free() usage, and
fixes related to boost handling.
Still, there is also a significant update of the intel_pstate driver
making it register an energy model when running on a hybrid platform
which is used for enabling energy-aware scheduling (EAS) if the driver
operates in the passive mode (and schedutil is used as the cpufreq
governor for all CPUs which is the passive mode default).
There are some amd-pstate driver updates too, for a good measure,
including the "Requested CPU Min frequency" BIOS option support and
new online/offline callbacks.
In the cpuidle space, the most significant change is the addition of a
C1 demotion on/off sysfs knob to intel_idle which should help some
users to configure their systems more precisely. There is also the
conversion of the PSCI cpuidle driver to a faux device one and there
are two small updates of cpuidle governors.
Device power management is also modified quite a bit, especially the
handling of devices with asynchronous suspend and resume enabled
during system transitions. They are now going to be handled more
asynchronously during suspend transitions and somewhat less
aggressively during resume transitions.
Apart from the above, the operating performance points (OPP) library
is now going to use mutex locking guards and scope-based cleanup
helpers and there is the usual bunch of assorted fixes and code
cleanups.

spi: Updates for v6.16
This bulk of the changes in this release are driver work, as well as
new device support we have some important work on performance over
several drivers, and big overhauls for maintainability on a couple too.
Highlights include:
- Big cleanups of the sh-msiof driver from Geert Uytterhoeven, and of
the NXP FSPI driver from Haibo Chen.
- Performance improvements for the AXI SPI engine.
- Support for writes to memory mapped flashes on Renesas devices.
- Integrated DMA support for Tegra210 QSPI, used by the Tegra234.
- DMA support for Amlogic SPI controllers.
- Support for AMD HID2, Qualcomm IPQ5018, Renesas RZ/G3E, Rockchip
RK3528 and Samsung Exynos Autov920.
An update to fix some issues with the Atmel QSPI driver runtime PM
pulled in a new API from the PM core, and the Renesas memory mapped
write changes pull in some code that's shared in drivers/memory.

"The bulk of the changes in this release are driver work, as well as
new device support we have some important work on performance over
several drivers, and big overhauls for maintainability on a couple
too. Highlights include:
- Big cleanups of the sh-msiof driver from Geert Uytterhoeven, and of
the NXP FSPI driver from Haibo Chen
- Performance improvements for the AXI SPI engine
- Support for writes to memory mapped flashes on Renesas devices
- Integrated DMA support for Tegra210 QSPI, used by the Tegra234
- DMA support for Amlogic SPI controllers
- Support for AMD HID2, Qualcomm IPQ5018, Renesas RZ/G3E, Rockchip
RK3528 and Samsung Exynos Autov920
An update to fix some issues with the Atmel QSPI driver runtime PM
pulled in a new API from the PM core, and the Renesas memory mapped
write changes pull in some code that's shared in drivers/memory"

gpio updates for v6.16-rc1
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where applicable
which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which will
take off the burden from GPIO drivers of checking this down the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter callbacks
- convert more drivers to making the irq_chip immutable as is recommended
by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built with
COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that makes
the setup easier for user-space than the existing driver-level sysfs
attributes and also adds more advanced configuration features (such as
referring to aggregated lines by their original names or modifying
their names as exposed by the aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the global
GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600 (new
drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents
Misc:
- TODO list updates

destroy_timer_on_stack() over to the canonical timer_*() namespace
convention.
There are is another large converstion pending, which has not been included

Updates for the MSI subsystem (core code and PCI):
- Switch the MSI decriptor locking to lock guards
- Replace a broken and naive implementation of PCI/MSI-X control word
updates in the PCI/TPH driver with a properly serialized variant in the
PCI/MSI core code.
- Remove the MSI descriptor abuse in the SCCI/UFS/QCOM driver by
replacing the direct access to the MSI descriptors with the proper API
function calls. People will never understand that APIs exist for a
reason...
- Provide core infrastructre for the upcoming PCI endpoint library
extensions. Currently limited to ARM GICv3+, but in theory extensible
to other architectures.
- Provide a MSI domain::teardown() callback, which allows drivers to undo
the effects of the prepare() callback.
- Move the MSI domain::prepare() callback invocation to domain creation
time to avoid redundant (and in case of ARM/GIC-V3-ITS confusing)
invocations on every allocation.
In combination with the new teardown callback this removes some ugly
hacks in the GIC-V3-ITS driver, which pretended to work around the
short comings of the core code so far. With this update the code is
correct by design and implementation.
- Make the irqchip MSI library globally available, provide a MSI parent
domain creation helper and convert a bunch of (PCI/)MSI drivers over to
the modern MSI parent mechanism. This is the first step to get rid of
at least one incarnation of the three PCI/MSI management schemes.
- The usual small cleanups and improvements

IIO: New device support, features and cleanup for 6.16 - take 2
Note - last minute rebase was to drop a typo patch that I'd accidentally picked up (in the microblaze arch Kconfig) Take 2 is due to that rebase messing up some fixes tags that were referring to patches after that point. There is a known merge conflict due to changes in neighbouring lines. Stephen's resolution in linux-next is: https://lore.kernel.org/linux-next/20250506155728.65605bae@canb.auug.org.au/ Added 3 named IIO reviewers to MAINTAINERS. This is a reflection of those who have been doing much of this work for some time. Lars-Peter is removed from the entry having moved on to other topics. Thanks Nuno, David and Andy for stepping up and Lars-Peter for all your hard work in the past! Includes the usual mix of new device support, features and general cleanup. This time we also have some tree wide changes. - Rip out the iio_device_claim_direct_scoped() as it proved hard to work with. This series includes quite a few related cleanups such as use of guard or factoring code out to allow direct returns. - Switch from iio_device_claim/release_direct_mode() to new iio_device_claim/release_direct() which is structured so that sparse can warn on failed releases. There were a few false positives but those were mostly in code that benefited from being cleaned up as part of this process. - Introduce iio_push_to_buffers_with_ts() to replace the _timestamp() version over time. This version takes the size of the supplied buffer which the core checks is at least as big as expected by calculation from channel descriptions of those channels enabled. Use this in an initial set of drivers. - Add macros for IIO_DECLARE_BUFFER_WITH_TS() and IIO_DECLARE_DMA_BUFFER_WITH_TS() to avoid lots of fiddly code to ensure correctly aligned buffers for timestamps being added onto the end of channel data. New device support ------------------ adi,ad3530r - New driver for AD3530, AD3530R, AD3531 and AD3531R DACs with programmable gain controls.

Includes some general driver cleanup and a separate dt binding. - Simplify reference voltage handling by assuming it is fixed after enabling the supply. winsen,mhz19b - New driver for this C02 sensor. Cleanup and minor fixes ----------------------- dt-bindings - Correct indentation and style for DTS examples. - Use unevalutateProperties for SPI devices instead of additionalProperties to allow generic SPI properties from spi-peripheral-props.yaml ABI Docs - Add missing docs for sampling_frequency when it applies only to events.

regmap: irq: Add support for chips without separate IRQ status
Some GPIO chips allow to rise an IRQ on GPIO level changes but do not provide an IRQ status for each separate line: only the current gpio level can be retrieved. Add support for these chips, emulating IRQ status by comparing GPIO levels with the levels during the previous interrupt.

mm/mempolicy: Weighted Interleave Auto-tuning
On machines with multiple memory nodes, interleaving page allocations across nodes allows for better utilization of each node's bandwidth. Previous work by Gregory Price [1] introduced weighted interleave, which allowed for pages to be allocated across nodes according to user-set ratios. Ideally, these weights should be proportional to their bandwidth, so that under bandwidth pressure, each node uses its maximal efficient bandwidth and prevents latency from increasing exponentially. Previously, weighted interleave's default weights were just 1s -- which would be equivalent to the (unweighted) interleave mempolicy, which goes through the nodes in a round-robin fashion, ignoring bandwidth information. This patch has two main goals: First, it makes weighted interleave easier to use for users who wish to relieve bandwidth pressure when using nodes with varying bandwidth (CXL). By providing a set of "real" default weights that just work out of the box, users who might not have the capability (or wish to) perform experimentation to find the most optimal weights for their system can still take advantage of bandwidth-informed weighted interleave. Second, it allows for weighted interleave to dynamically adjust to hotplugged memory with new bandwidth information. Instead of manually updating node weights every time new bandwidth information is reported or taken off, weighted interleave adjusts and provides a new set of default weights for weighted interleave to use when there is a change in bandwidth information. To meet these goals, this patch introduces an auto-configuration mode for the interleave weights that provides a reasonable set of default weights, calculated using bandwidth data reported by the system. In auto mode, weights are dynamically adjusted based on whatever the current bandwidth information reports (and responds to hotplug events). This patch still supports users manually writing weights into the nodeN sysfs interface by entering into manual mode. When a user enters manual mode, the system stops dynamically updating any of the node weights, even during hotplug events that shift the optimal weight distribution. A new sysfs interface "auto" is introduced, which allows users to switch between the auto (writing 1 or Y) and manual (writing 0 or N) modes. The system also automatically enters manual mode when a nodeN interface is manually written to. There is one functional change that this patch makes to the existing weighted_interleave ABI: previously, writing 0 directly to a nodeN interface was said to reset the weight to the system default. Before this patch, the default for all weights were 1, which meant that writing 0 and 1 were functionally equivalent. With this patch, writing 0 is invalid.

regmap: Move selecting for REGMAP_MDIO and REGMAP_IRQ
If either REGMAP_IRQ or REGMAP_MDIO are set then REGMAP is also set. This then enables the selecting of IRQ_DOMAIN or MDIO_BUS from REGMAP based on the above two symbols respectively. This makes it very easy to end up with "circular dependencies". Instead select the IRQ_DOMAIN or MDIO_BUS from the symbols that make use of them. This is almost equivalent to before but makes it less likely to end up with false circular dependency detections.

PM: runtime: fix denying of auto suspend in pm_suspend_timer_fn()
pm_runtime_put_autosuspend() schedules a hrtimer to expire
at "dev->power.timer_expires". If the hrtimer's callback,
pm_suspend_timer_fn(), observes that the current time equals
"dev->power.timer_expires", it unexpectedly bails out instead of
proceeding with runtime suspend.
pm_suspend_timer_fn():
if (expires > 0 && expires < ktime_get_mono_fast_ns()) {
dev->power.timer_expires = 0;
rpm_suspend(..)
}
Additionally, as ->timer_expires is not cleared, all the future auto
suspend requests will not schedule hrtimer to perform auto suspend.
rpm_suspend():
if ((rpmflags & RPM_AUTO) &&...) {
if (!(dev->power.timer_expires && ...) { <-- this will fail.
hrtimer_start_range_ns(&dev->power.suspend_timer,...);
}
}
Fix this by as well checking if current time reaches the set expiration.

Add more devm_ functions to fix PM imbalance in
Merge series from Bence Csókás <csokas.bence@prolan.hu>: The probe() function of the atmel-quadspi driver got quite convoluted, especially since the addition of SAMA7G5 support, that was forward-ported from an older vendor kernel. During the port, a bug was introduced, where the PM get() and put() calls were imbalanced. To alleivate this - and similar problems in the future - an effort was made to migrate as many functions as possible, to their devm_ managed counterparts. The few functions, which did not yet have a devm_ variant, are added in patch 1 of this series. Patch 2 then uses these APIs to fix the probe() function. |

memory: implement memory_block_advise/probe_max_size
Patch series "memory,x86,acpi: hotplug memory alignment advisement", v8.
When physical address regions are not aligned to memory block size, the
misaligned portion is lost (stranded capacity).
Block size (min/max/selected) is architecture defined. Most architectures
tend to use the minimum block size or some simplistic heurist. On x86,
memory block size increases up to 2GB, and is otherwise fitted to the
alignment of non-hotplug (i.e. not special purpose memory).
CXL exposes its memory for management through the ACPI CEDT (CXL Early
Detection Table) in a field called the CXL Fixed Memory Window. Per the
CXL specification, this memory must be aligned to at least 256MB.
When a CFMW aligns on a size less than the block size, this causes a loss
of up to 2GB per CFMW on x86. It is not uncommon for CFMW to be allocated
per-device - though this behavior is BIOS defined.
This patch set provides 3 things:
1) implement advise/query functions in driverse/base/memory.c to
report/query architecture agnostic hotplug block alignment advice.
2) update x86 memblock size logic to consider the hotplug advice
3) add code in acpi/numa/srat.c to report CFMW alignment advice
The advisement interfaces are design to be called during arch_init code
prior to allocator and smp_init. start_kernel will call these through
setup_arch() (via acpi and mm/init_64.c on x86), which occurs prior to
mm_core_init and smp_init - so no need for atomics.
There's an attempt to signal callers to advise() that query has already
occurred, but this is predicated on the notion that query actually occurs
(which presently only happens on the x86 arch). This is to assist
debugging future users. Otherwise, the advise() call has been marked
__init to help static discovery of bad call times.
Once query is called the first time, it will always return the same value.
Interfaces return -EBUSY and 0 respectively on systems without hotplug.
This patch (of 3):
Hotplug memory sources may have opinions on what the memblock size should
be - usually for alignment purposes. For example, CXL memory extents can
be 256MB with a matching alignment. If this size/alignment is smaller
than the block size, it can result in stranded capacity.
Implement memory_block_advise_max_size for use prior to allocator init,
for software to advise the system on the max block size.
Implement memory_block_probe_max_size for use by arch init code to
calculate the best block size. Use of advice is architecture defined.
The probe value can never change after first probe. Calls to advise after
probe will return -EBUSY to aid debugging.
On systems without hotplug, always return -ENODEV and 0 respectively.

Pull x86 ITS mitigation from Dave Hansen:
"Mitigate Indirect Target Selection (ITS) issue.
I'd describe this one as a good old CPU bug where the behavior is
_obviously_ wrong, but since it just results in bad predictions it
wasn't wrong enough to notice. Well, the researchers noticed and also
realized that thus bug undermined a bunch of existing indirect branch
mitigations.
Thus the unusually wide impact on this one. Details:
ITS is a bug in some Intel CPUs that affects indirect branches
including RETs in the first half of a cacheline. Due to ITS such
branches may get wrongly predicted to a target of (direct or indirect)
branch that is located in the second half of a cacheline. Researchers
at VUSec found this behavior and reported to Intel.
Affected processors:
- Cascade Lake, Cooper Lake, Whiskey Lake V, Coffee Lake R, Comet
Lake, Ice Lake, Tiger Lake and Rocket Lake.
Scope of impact:
- Guest/host isolation:
When eIBRS is used for guest/host isolation, the indirect branches
in the VMM may still be predicted with targets corresponding to
direct branches in the guest.
- Intra-mode using cBPF:
cBPF can be used to poison the branch history to exploit ITS.
Realigning the indirect branches and RETs mitigates this attack
vector.
- User/kernel:
With eIBRS enabled user/kernel isolation is *not* impacted by ITS.
- Indirect Branch Prediction Barrier (IBPB):
Due to this bug indirect branches may be predicted with targets
corresponding to direct branches which were executed prior to IBPB.
This will be fixed in the microcode.
Mitigation:
As indirect branches in the first half of cacheline are affected, the
mitigation is to replace those indirect branches with a call to thunk that
is aligned to the second half of the cacheline.
RETs that take prediction from RSB are not affected, but they may be
affected by RSB-underflow condition. So, RETs in the first half of
cacheline are also patched to a return thunk that executes the RET aligned
to second half of cacheline"

x86/its: Enable Indirect Target Selection mitigation
Indirect Target Selection (ITS) is a bug in some pre-ADL Intel CPUs with eIBRS. It affects prediction of indirect branch and RETs in the lower half of cacheline. Due to ITS such branches may get wrongly predicted to a target of (direct or indirect) branch that is located in the upper half of the cacheline. Scope of impact =============== Guest/host isolation -------------------- When eIBRS is used for guest/host isolation, the indirect branches in the VMM may still be predicted with targets corresponding to branches in the guest. Intra-mode ---------- cBPF or other native gadgets can be used for intra-mode training and disclosure using ITS. User/kernel isolation --------------------- When eIBRS is enabled user/kernel isolation is not impacted. Indirect Branch Prediction Barrier (IBPB) ----------------------------------------- After an IBPB, indirect branches may be predicted with targets corresponding to direct branches which were executed prior to IBPB. This is mitigated by a microcode update. Add cmdline parameter indirect_target_selection=off|on|force to control the mitigation to relocate the affected branches to an ITS-safe thunk i.e. located in the upper half of cacheline. Also add the sysfs reporting. When retpoline mitigation is deployed, ITS safe-thunks are not needed, because retpoline sequence is already ITS-safe. Similarly, when call depth tracking (CDT) mitigation is deployed (retbleed=stuff), ITS safe return thunk is not used, as CDT prevents RSB-underflow. To not overcomplicate things, ITS mitigation is not supported with spectre-v2 lfence;jmp mitigation. Moreover, it is less practical to deploy lfence;jmp mitigation on ITS affected parts anyways.

PM: sysfs: Move debug runtime PM attributes to runtime_attrs[]
Some of the debug sysfs attributes for runtime PM are located in the power_attrs[] table, so they are exposed even in the pm_runtime_has_no_callbacks() case, unlike the other non-debug sysfs attributes for runtime PM, which may be confusing. Moreover, dev_attr_runtime_status.attr appears in two places, which effectively causes it to be always exposed if CONFIG_PM_ADVANCED_DEBUG is set, but otherwise it is exposed only when pm_runtime_has_no_callbacks() returns 'false'.

arch_topology: Relocate cpu_scale to topology.[h|c]
arch_topology.c provides functionality to parse and scale CPU capacity. It also provides a corresponding sysfs interface. Some architectures parse and scale CPU capacity differently as per their own needs. On Intel processors, for instance, it is responsibility of the Intel P-state driver. Relocate the implementation of that interface to a common location in topology.c. Architectures can use the interface and populate it using their own mechanisms. An alternative approach would be to compile arch_topology.c even if not needed only to get this interface. This approach would create duplicated and conflicting functionality and data structures.

platform-msi: Add msi_remove_device_irq_domain() in platform_device_msi_free_irqs_all()
platform_device_msi_init_and_alloc_irqs() performs two tasks: allocating the MSI domain for a platform device, and allocate a number of MSIs in that domain. platform_device_msi_free_irqs_all() only frees the MSIs, and leaves the MSI domain alive. Given that platform_device_msi_init_and_alloc_irqs() is the sole tool a platform device has to allocate platform MSIs, it makes sense for platform_device_msi_free_irqs_all() to teardown the MSI domain at the same time as the MSIs. This avoids warnings and unexpected behaviours when a driver repeatedly allocates and frees MSIs.

To avoid a race between the IOMMU probing thread and the device driver
async probing thread during configuration of the platform DMA, update
`platform_dma_configure()` to read `dev->driver` once and test if it's
NULL before using it. This ensures that we don't de-reference an invalid
platform driver pointer if the device driver is asynchronously bound
while configuring the DMA.

The lesson to learn from this might just be that we need to threaten code removal more often!? - Fix a regression introduced by enabling large folios for lage logical block sizes. This has caused issues for noref migration with large folios due to sleeping while in an atomic context. New sleeping variants of pagecache lookup helpers are introduced. These helpers take the folio lock instead of the mapping's private spinlock. The problematic users are converted to the sleeping variants and serialize against noref migration. Atomic users will bail on seeing the new BH_Migrate flag. This also shrinks the critical region of the mapping's private lock and the new blocking callers reduce contention on the spinlock for bdev mappings. - Fix two bugs in do_move_mount() when with MOVE_MOUNT_BENEATH.

driver core: auxiliary bus: Fix IS_ERR() vs NULL mixup in __devm_auxiliary_device_create()
This code was originally going to use error pointers but we decided it
should return NULL instead. The error pointer code in
__devm_auxiliary_device_create() was left over from the first version.
Update it to use NULL. No callers have been merged yet, so that makes
this change simple and self contained.

devtmpfs: don't use vfs_getattr_nosec to query i_mode
The recent move of the bdev_statx call to the low-level vfs_getattr_nosec
helper caused it being used by devtmpfs, which leads to deadlocks in
md teardown due to the block device lookup and put interfering with the
unusual lifetime rules in md.
But as handle_remove only works on inodes created and owned by devtmpfs
itself there is no need to use vfs_getattr_nosec vs simply reading the
mode from the inode directly. Switch to that to avoid the bdev lookup
or any other unintentional side effect.

property: Add functions to iterate named child
There are a few use-cases where child nodes with a specific name need to be parsed. Code like: fwnode_for_each_child_node() if (fwnode_name_eq()) ... can be found from a various drivers/subsystems. Adding a macro for this can simplify things a bit. In a few cases the data from the found nodes is later added to an array, which is allocated based on the number of found nodes. One example of such use is the IIO subsystem's ADC channel nodes, where the relevant nodes are named as channel[@N]. Add helpers for iterating and counting device's sub-nodes with certain name instead of open-coding this in every user.

PM: sleep: Resume children after resuming the parent
According to [1], the handling of device suspend and resume, and particularly the latter, involves unnecessary overhead related to starting new async work items for devices that cannot make progress right away because they have to wait for other devices. To reduce this problem in the resume path, use the observation that starting the async resume of the children of a device after resuming the parent is likely to produce less scheduling and memory management noise than starting it upfront while at the same time it should not increase the resume duration substantially. Accordingly, modify the code to start the async resume of the device's children when the processing of the parent has been completed in each stage of device resume and only start async resume upfront for devices without parents. Also make it check if a given device can be resumed asynchronously before starting the synchronous resume of it in case it will have to wait for another that is already resuming asynchronously. In addition to making the async resume of devices more friendly to systems with relatively less computing resources, this change is also preliminary for analogous changes in the suspend path. On the systems where it has been tested, this change by itself does not affect the overall system resume duration in a measurable way.

x86/cpu: Help users notice when running old Intel microcode
Old microcode is bad for users and for kernel developers.
For users, it exposes them to known fixed security and/or functional
issues. These obviously rarely result in instant dumpster fires in
every environment. But it is as important to keep your microcode up
to date as it is to keep your kernel up to date.
Old microcode also makes kernels harder to debug. A developer looking
at an oops need to consider kernel bugs, known CPU issues and unknown
CPU issues as possible causes. If they know the microcode is up to
date, they can mostly eliminate known CPU issues as the cause.
Make it easier to tell if CPU microcode is out of date. Add a list
of released microcode. If the loaded microcode is older than the
release, tell users in a place that folks can find it:
/sys/devices/system/cpu/vulnerabilities/old_microcode
Tell kernel kernel developers about it with the existing taint
flag:
TAINT_CPU_OUT_OF_SPEC
== Discussion ==
When a user reports a potential kernel issue, it is very common
to ask them to reproduce the issue on mainline. Running mainline,
they will (independently from the distro) acquire a more up-to-date
microcode version list. If their microcode is old, they will
get a warning about the taint and kernel developers can take that
into consideration when debugging.
Just like any other entry in "vulnerabilities/", users are free to
make their own assessment of their exposure.
== Microcode Revision Discussion ==
The microcode versions in the table were generated from the Intel
microcode git repo:
8ac9378a8487 ("microcode-20241112 Release")
which as of this writing lags behind the latest microcode-20250211.
It can be argued that the versions that the kernel picks to call "old"
should be a revision or two old. Which specific version is picked is
less important to me than picking *a* version and enforcing it.
This repository contains only microcode versions that Intel has deemed
to be OS-loadable. It is quite possible that the BIOS has loaded a
newer microcode than the latest in this repo. If this happens, the
system is considered to have new microcode, not old.
Specifically, the sysfs file and taint flag answer the question:
Is the CPU running on the latest OS-loadable microcode,
or something even later that the BIOS loaded?
In other words, Intel never publishes an authoritative list of CPUs
and latest microcode revisions. Until it does, this is the best that
Linux can do.
Also note that the "intel-ucode-defs.h" file is simple, ugly and
has lots of magic numbers. That's on purpose and should allow a
single file to be shared across lots of stable kernel regardless of if
they have the new "VFM" infrastructure or not. It was generated with
a dumb script.
== FAQ ==
Q: Does this tell me if my system is secure or insecure?
A: No. It only tells you if your microcode was old when the
system booted.
Q: Should the kernel warn if the microcode list itself is too old?
A: No. New kernels will get new microcode lists, both mainline
and stable. The only way to have an old list is to be running
an old kernel in which case you have bigger problems.
Q: Is this for security or functional issues?
A: Both.
Q: If a given microcode update only has functional problems but
no security issues, will it be considered old?
A: Yes. All microcode image versions within a microcode release
are treated identically. Intel appears to make security
updates without disclosing them in the release notes. Thus,
all updates are considered to be security-relevant.
Q: Who runs old microcode?
A: Anybody with an old distro. This happens all the time inside
of Intel where there are lots of weird systems in labs that
might not be getting regular distro updates and might also
be running rather exotic microcode images.
Q: If I update my microcode after booting will it stop saying
"Vulnerable"?
A: No. Just like all the other vulnerabilies, you need to
reboot before the kernel will reassess your vulnerability.

driver core: auxiliary bus: add device creation helpers
Add helper functions to create a device on the auxiliary bus. This is meant for fairly simple usage of the auxiliary bus, to avoid having the same code repeated in the different drivers.

driver core: faux: Add sysfs groups after probing
Manually add sysfs groups after the faux_device_ops's probe succeeds. Likewise remove these groups just before calling the faux_devices_ops's remove callback. This approach approximates the order in which the driver core adds and removes the driver's .dev_groups of a device to avoid lifetime issues. This is done specifically to avoid using the device's .groups member, which adds groups before the device is even registered to the bus. This lets consumers of this API, initialize resources on the .probe callback and then use them inside is_visible/show/store methods, through dev_get_drvdata() without races. Cc: Rafael J.

device property: Split fwnode_get_child_node_count()
The new helper is introduced to allow counting the child firmware nodes of their parent without requiring a device to be passed.

Driver core updates for 6.15-rc1
Here is the big set of driver core updates for 6.15-rc1. Lots of stuff
happened this development cycle, including:
- kernfs scaling changes to make it even faster thanks to rcu
- bin_attribute constify work in many subsystems
- faux bus minor tweaks for the rust bindings
- rust binding updates for driver core, pci, and platform busses,
making more functionaliy available to rust drivers. These are all
due to people actually trying to use the bindings that were in 6.14.
- make Rafael and Danilo full co-maintainers of the driver core
codebase
- other minor fixes and updates.
This has been in linux-next for a while now, with the only reported
issue being some merge conflicts with the rust tree. Depending on which
tree you pull first, you will have conflicts in one of them. The merge
resolution has been in linux-next as an example of what to do, or can be
found here:

- The 6 patch series "Enable strict percpu address space checks" from
Uros Bizjak uses x86 named address space qualifiers to provide compile-time checking of percpu area accesses. This has caused a small amount of fallout - two or three issues were reported. In all cases the calling code was founf to be incorrect. - The 4 patch series "Some cleanup for memcg" from Chen Ridong implements some relatively monir cleanups for the memcontrol code. - The 17 patch series "mm: fixes for device-exclusive entries (hmm)" from David Hildenbrand fixes a boatload of issues which David found then using device-exclusive PTE entries when THP is enabled. More work is needed, but this makes thins better - our own HMM selftests now succeed. - The 2 patch series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed remove the z3fold and zbud implementations. They have been deprecated for half a year and nobody has complained. - The 5 patch series "mm: further simplify VMA merge operation" from Lorenzo Stoakes implements numerous simplifications in this area. No runtime effects are anticipated. - The 4 patch series "mm/madvise: remove redundant mmap_lock operations from process_madvise()" from SeongJae Park rationalizes the locking in the madvise() implementation. Performance gains of 20-25% were observed in one MADV_DONTNEED microbenchmark. - The 12 patch series "Tiny cleanup and improvements about SWAP code" from Baoquan He contains a number of touchups to issues which Baoquan noticed when working on the swap code. - The 2 patch series "mm: kmemleak: Usability improvements" from Catalin Marinas implements a couple of improvements to the kmemleak user-visible output. - The 2 patch series "mm/damon/paddr: fix large folios access and schemes handling" from Usama Arif provides a couple of fixes for DAMON's handling of large folios. - The 3 patch series "mm/damon/core: fix wrong and/or useless damos_walk() behaviors" from SeongJae Park fixes a few issues with the accuracy of kdamond's walking of DAMON regions. - The 3 patch series "expose mapping wrprotect, fix fb_defio use" from Lorenzo Stoakes changes the interaction between framebuffer deferred-io and core MM. No functional changes are anticipated - this is preparatory work for the future removal of page structure fields. - The 4 patch series "mm/damon: add support for hugepage_size DAMOS filter" from Usama Arif adds a DAMOS filter which permits the filtering by huge page sizes. - The 4 patch series "mm: permit guard regions for file-backed/shmem mappings" from Lorenzo Stoakes extends the guard region feature from its present "anon mappings only" state. The feature now covers shmem and file-backed mappings. - The 4 patch series "mm: batched unmap lazyfree large folios during reclamation" from Barry Song cleans up and speeds up the unmapping for pte-mapped large folios. - The 18 patch series "reimplement per-vma lock as a refcount" from Suren Baghdasaryan puts the vm_lock back into the vma. Our reasons for pulling it out were largely bogus and that change made the code more messy. This patchset provides small (0-10%) improvements on one microbenchmark. - The 5 patch series "Docs/mm/damon: misc DAMOS filters documentation fixes and improves" from SeongJae Park does some maintenance work on the DAMON docs. - The 27 patch series "hugetlb/CMA improvements for large systems" from Frank van der Linden addresses a pile of issues which have been observed when using CMA on large machines. - The 2 patch series "mm/damon: introduce DAMOS filter type for unmapped pages" from SeongJae Park enables users of DMAON/DAMOS to filter my the page's mapped/unmapped status. - The 19 patch series "zsmalloc/zram: there be preemption" from Sergey Senozhatsky teaches zram to run its compression and decompression operations preemptibly. - The 12 patch series "selftests/mm: Some cleanups from trying to run them" from Brendan Jackman fixes a pile of unrelated issues which Brendan encountered while runnimg our selftests. - The 2 patch series "fs/proc/task_mmu: add guard region bit to pagemap" from Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to determine whether a particular page is a guard page. - The 7 patch series "mm, swap: remove swap slot cache" from Kairui Song removes the swap slot cache from the allocation path - it simply wasn't being effective. - The 5 patch series "mm: cleanups for device-exclusive entries (hmm)" from David Hildenbrand implements a number of unrelated cleanups in this code. - The 5 patch series "mm: Rework generic PTDUMP configs" from Anshuman Khandual implements a number of preparatoty cleanups to the GENERIC_PTDUMP Kconfig logic. - The 8 patch series "mm/damon: auto-tune aggregation interval" from SeongJae Park implements a feedback-driven automatic tuning feature for DAMON's aggregation interval tuning. - The 5 patch series "Fix lazy mmu mode" from Ryan Roberts fixes some issues in powerpc, sparc and x86 lazy MMU implementations. Ryan did this in preparation for implementing lazy mmu mode for arm64 to optimize vmalloc. - The 2 patch series "mm/page_alloc: Some clarifications for migratetype fallback" from Brendan Jackman reworks some commentary to make the code easier to follow. - The 3 patch series "page_counter cleanup and size reduction" from Shakeel Butt cleans up the page_counter code and fixes a size increase which we accidentally added late last year. - The 3 patch series "Add a command line option that enables control of how many threads should be used to allocate huge pages" from Thomas Prescher does that. It allows the careful operator to significantly reduce boot time by tuning the parallalization of huge page initialization. - The 3 patch series "Fix calculations in trace_balance_dirty_pages() for cgwb" from Tang Yizhou fixes the tracing output from the dirty page balancing code. - The 9 patch series "mm/damon: make allow filters after reject filters useful and intuitive" from SeongJae Park improves the handling of allow and reject filters. Behaviour is made more consistent and the documention is updated accordingly. - The 5 patch series "Switch zswap to object read/write APIs" from Yosry Ahmed updates zswap to the new object read/write APIs and thus permits the removal of some legacy code from zpool and zsmalloc. - The 6 patch series "Some trivial cleanups for shmem" from Baolin Wang does as it claims. - The 20 patch series "fs/dax: Fix ZONE_DEVICE page reference counts" from Alistair Popple regularizes the weird ZONE_DEVICE page refcount handling in DAX, permittig the removal of a number of special-case checks. - The 4 patch series "refactor mremap and fix bug" from Lorenzo Stoakes is a preparatoty refactoring and cleanup of the mremap() code. - The 20 patch series "mm: MM owner tracking for large folios (!hugetlb) + CONFIG_NO_PAGE_MAPCOUNT" from David Hildenbrand reworks the manner in which we determine whether a large folio is known to be mapped exclusively into a single MM. - The 8 patch series "mm/damon: add sysfs dirs for managing DAMOS filters based on handling layers" from SeongJae Park adds a couple of new sysfs directories to ease the management of DAMON/DAMOS filters. - The 13 patch series "arch, mm: reduce code duplication in mem_init()" from Mike Rapoport consolidates many per-arch implementations of mem_init() into code generic code, where that is practical. - The 13 patch series "mm/damon/sysfs: commit parameters online via damon_call()" from SeongJae Park continues the cleaning up of sysfs access to DAMON internal data. - The 3 patch series "mm: page_ext: Introduce new iteration API" from Luiz Capitulino reworks the page_ext initialization to fix a boot-time crash which was observed with an unusual combination of compile and cmdline options. - The 8 patch series "Buddy allocator like (or non-uniform) folio split" from Zi Yan reworks the code to split a folio into smaller folios. The main benefit is lessened memory consumption: fewer post-split folios are generated. - The 2 patch series "Minimize xa_node allocation during xarry split" from Zi Yan reduces the number of xarray xa_nodes which are generated during an xarray split. - The 2 patch series "drivers/base/memory: Two cleanups" from Gavin Shan performs some maintenance work on the drivers/base/memory code. - The 3 patch series "Add tracepoints for lowmem reserves, watermarks and totalreserve_pages" from Martin Liu adds some more tracepoints to the page allocator code. - The 4 patch series "mm/madvise: cleanup requests validations and classifications" from SeongJae Park cleans up some warts which SeongJae observed during his earlier madvise work. - The 3 patch series "mm/hwpoison: Fix regressions in memory failure handling" from Shuai Xue addresses two quite serious regressions which Shuai has observed in the memory-failure implementation. - The 5 patch series "mm: reliable huge page allocator" from Johannes Weiner makes huge page allocations cheaper and more reliable by reducing fragmentation. - The 5 patch series "Minor memcg cleanups & prep for memdescs" from Matthew Wilcox is preparatory work for the future implementation of memdescs. - The 4 patch series "track memory used by balloon drivers" from Nico Pache introduces a way to track memory used by our various balloon drivers. - The 2 patch series "mm/damon: introduce DAMOS filter type for active pages" from Nhat Pham permits users to filter for active/inactive pages, separately for file and anon pages. - The 2 patch series "Adding Proactive Memory Reclaim Statistics" from Hao Jia separates the proactive reclaim statistics from the direct reclaim statistics. - The 2 patch series "mm/vmscan: don't try to reclaim hwpoison folio" from Jinjiang Tu fixes our handling of hwpoisoned pages within the reclaim code. -----BEGIN PGP SIGNATURE----- iHQEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCZ+nZaAAKCRDdBJ7gKXxA jsOWAPiP4r7CJHMZRK4eyJOkvS1a1r+TsIarrFZtjwvf/GIfAQCEG+JDxVfUaUSF Ee93qSSLR1BkNdDw+931Pu0mXfbnBw== =Pn2K -----END PGP SIGNATURE----- Merge tag 'mm-stable-2025-03-30-16-52' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - The series "Enable strict percpu address space checks" from Uros Bizjak uses x86 named address space qualifiers to provide compile-time checking of percpu area accesses.

Behaviour is made more consistent and the documention is updated accordingly. - The series "Switch zswap to object read/write APIs" from Yosry Ahmed updates zswap to the new object read/write APIs and thus permits the removal of some legacy code from zpool and zsmalloc. - The series "Some trivial cleanups for shmem" from Baolin Wang does as it claims. - The series "fs/dax: Fix ZONE_DEVICE page reference counts" from Alistair Popple regularizes the weird ZONE_DEVICE page refcount handling in DAX, permittig the removal of a number of special-case checks. - The series "refactor mremap and fix bug" from Lorenzo Stoakes is a preparatoty refactoring and cleanup of the mremap() code. - The series "mm: MM owner tracking for large folios (!hugetlb) + CONFIG_NO_PAGE_MAPCOUNT" from David Hildenbrand reworks the manner in which we determine whether a large folio is known to be mapped exclusively into a single MM. - The series "mm/damon: add sysfs dirs for managing DAMOS filters based on handling layers" from SeongJae Park adds a couple of new sysfs directories to ease the management of DAMON/DAMOS filters. - The series "arch, mm: reduce code duplication in mem_init()" from Mike Rapoport consolidates many per-arch implementations of mem_init() into code generic code, where that is practical. - The series "mm/damon/sysfs: commit parameters online via damon_call()" from SeongJae Park continues the cleaning up of sysfs access to DAMON internal data. - The series "mm: page_ext: Introduce new iteration API" from Luiz Capitulino reworks the page_ext initialization to fix a boot-time crash which was observed with an unusual combination of compile and cmdline options. - The series "Buddy allocator like (or non-uniform) folio split" from Zi Yan reworks the code to split a folio into smaller folios. The main benefit is lessened memory consumption: fewer post-split folios are generated. - The series "Minimize xa_node allocation during xarry split" from Zi Yan reduces the number of xarray xa_nodes which are generated during an xarray split. - The series "drivers/base/memory: Two cleanups" from Gavin Shan performs some maintenance work on the drivers/base/memory code. - The series "Add tracepoints for lowmem reserves, watermarks and totalreserve_pages" from Martin Liu adds some more tracepoints to the page allocator code. - The series "mm/madvise: cleanup requests validations and classifications" from SeongJae Park cleans up some warts which SeongJae observed during his earlier madvise work. - The series "mm/hwpoison: Fix regressions in memory failure handling" from Shuai Xue addresses two quite serious regressions which Shuai has observed in the memory-failure implementation. - The series "mm: reliable huge page allocator" from Johannes Weiner makes huge page allocations cheaper and more reliable by reducing fragmentation. - The series "Minor memcg cleanups & prep for memdescs" from Matthew Wilcox is preparatory work for the future implementation of memdescs. - The series "track memory used by balloon drivers" from Nico Pache introduces a way to track memory used by our various balloon drivers. - The series "mm/damon: introduce DAMOS filter type for active pages" from Nhat Pham permits users to filter for active/inactive pages, separately for file and anon pages. - The series "Adding Proactive Memory Reclaim Statistics" from Hao Jia separates the proactive reclaim statistics from the direct reclaim statistics. - The series "mm/vmscan: don't try to reclaim hwpoison folio" from Jinjiang Tu fixes our handling of hwpoisoned pages within the reclaim code. * tag 'mm-stable-2025-03-30-16-52' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (431 commits) mm/page_alloc: remove unnecessary __maybe_unused in order_to_pindex() x86/mm: restore early initialization of high_memory for 32-bits mm/vmscan: don't try to reclaim hwpoison folio mm/hwpoison: introduce folio_contain_hwpoisoned_page() helper cgroup: docs: add pswpin and pswpout items in cgroup v2 doc mm: vmscan: split proactive reclaim statistics from direct reclaim statistics selftests/mm: speed up split_huge_page_test selftests/mm: uffd-unit-tests support for hugepages > 2M docs/mm/damon/design: document active DAMOS filter type mm/damon: implement a new DAMOS filter type for active pages fs/dax: don't disassociate zero page entries MM documentation: add "Unaccepted" meminfo entry selftests/mm: add commentary about 9pfs bugs fork: use __vmalloc_node() for stack allocation docs/mm: Physical Memory: Populate the "Zones" section xen: balloon: update the NR_BALLOON_PAGES state hv_balloon: update the NR_BALLOON_PAGES state balloon_compaction: update the NR_BALLOON_PAGES state meminfo: add a per node counter for balloon drivers mm: remove references to folio in __memcg_kmem_uncharge_page() ... |

Merge tag 'pci-v6.15-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Enable Configuration RRS SV, which makes device readiness visible,
early instead of during child bus scanning (Bjorn Helgaas)
- Log debug messages about reset methods being used (Bjorn Helgaas)
- Avoid reset when it has been disabled via sysfs (Nishanth
Aravamudan)
- Add common pci-ep-bus.yaml schema for exporting several peripherals
of a single PCI function via devicetree (Andrea della Porta)
- Create DT nodes for PCI host bridges to enable loading device tree
overlays to create platform devices for PCI devices that have
several features that require multiple drivers (Herve Codina)
Resource management:
- Enlarge devres table[] to accommodate bridge windows, ROM, IOV
BARs, etc., and validate BAR index in devres interfaces (Philipp
Stanner)
- Fix typo that repeatedly distributed resources to a bridge instead
of iterating over subordinate bridges, which resulted in too little
space to assign some BARs (Kai-Heng Feng)
- Relax bridge window tail sizing for optional resources, e.g., IOV
BARs, to avoid failures when removing and re-adding devices (Ilpo
Järvinen)
- Allow drivers to enable devices even if we haven't assigned
optional IOV resources to them (Ilpo Järvinen)
- Rework handling of optional resources (IOV BARs, ROMs) to reduce
failures if we can't allocate them (Ilpo Järvinen)
- Fix a NULL dereference in the SR-IOV VF creation error path (Shay
Drory)
- Fix s390 mmio_read/write syscalls, which didn't cause page faults
in some cases, which broke vfio-pci lazy mapping on first access
(Niklas Schnelle)

ASPM:
- Delay pcie_link_state deallocation to avoid dangling pointers that
cause invalid references during hot-unplug (Daniel Stodden)
Power management:
- Allow PCI bridges to go to D3Hot when suspending on all non-x86
systems (Manivannan Sadhasivam)
Power control:
- Create pwrctrl devices in pci_scan_device() to make it more
symmetric with pci_pwrctrl_unregister() and make pwrctrl devices
for PCI bridges possible (Manivannan Sadhasivam)
- Unregister pwrctrl devices in pci_destroy_dev() so DOE, ASPM, etc.
can still access devices after pci_stop_dev() (Manivannan
Sadhasivam)
- If there's a pwrctrl device for a PCI device, skip scanning it
because the pwrctrl core will rescan the bus after the device is
powered on (Manivannan Sadhasivam)
- Add a pwrctrl driver for PCI slots based on voltage regulators
described via devicetree (Manivannan Sadhasivam)
Bandwidth control:
- Add set_pcie_speed.sh to TEST_PROGS to fix issue when executing the
set_pcie_cooling_state.sh test case (Yi Lai)
- Avoid a NULL pointer dereference when we run out of bus numbers to
assign for a bridge secondary bus (Lukas Wunner)
Hotplug:
- Drop superfluous pci_hotplug_slot_list, try_module_get() calls, and
NULL pointer checks (Lukas Wunner)
- Drop shpchp module init/exit logging, replace shpchp dbg() with
ctrl_dbg(), and remove unused dbg(), err(), info(), warn() wrappers
(Ilpo Järvinen)
- Drop 'shpchp_debug' module parameter in favor of standard dynamic
debugging (Ilpo Järvinen)
- Drop unused cpcihp .get_power(), .set_power() function pointers
(Guilherme Giacomo Simoes)
- Disable hotplug interrupts in portdrv only when pciehp is not
enabled to avoid issuing two hotplug commands too close together
(Feng Tang)
- Skip pciehp 'device replaced' check if the device has been removed
to address a deadlock when resuming after a device was removed
during system sleep (Lukas Wunner)
- Don't enable pciehp hotplug interupt when resuming in poll mode
(Ilpo Järvinen)
Virtualization:
- Fix bugs in 'pci=config_acs=' kernel command line parameter (Tushar
Dave)
DOE:
- Expose supported DOE features via sysfs (Alistair Francis)
- Allow DOE support to be enabled even if CXL isn't enabled (Alistair
Francis)
Endpoint framework:
- Convert PCI device data so pci-epf-test works correctly on
big-endian endpoint systems (Niklas Cassel)
- Add BAR_RESIZABLE type to endpoint framework and add DWC core
support for EPF drivers to set BAR_RESIZABLE type and size (Niklas
Cassel)
- Fix pci-epf-test double free that causes an oops if the host
reboots and PERST# deassertion restarts endpoint BAR allocation
(Christian Bruel)
- Fix endpoint BAR testing so tests can skip disabled BARs instead of
reporting them as failures (Niklas Cassel)
- Widen endpoint test BAR size variable to accommodate BARs larger
than INT_MAX (Niklas Cassel)
- Remove unused tools 'pci' build target left over after moving tests
to tools/testing/selftests/pci_endpoint (Jianfeng Liu)

- Apply link speed restriction before bringing link up, not after
(Jim Quinlan)
- Update Max Link Speed in Link Capabilities via the internal
writable register, not the read-only config register (Jim Quinlan)
- Handle regulator_bulk_get() error to avoid panic when we call
regulator_bulk_free() later (Jim Quinlan)
- Disable regulators only when removing the bus immediately below a
Root Port because we don't support regulators deeper in the
hierarchy (Jim Quinlan)

- Correct MSG TLP generation so endpoints can generate INTx messages
(Hans Zhang)
Freescale i.MX6 PCIe controller driver:

Intel VMD host bridge driver:
- Convert vmd_dev.cfg_lock from spinlock_t to raw_spinlock_t so
pci_ops.read() will never sleep, even on PREEMPT_RT where
spinlock_t becomes a sleepable lock, to avoid calling a sleeping
function from invalid context (Ryo Takakura)
MediaTek PCIe Gen3 controller driver:
- Remove leftover mac_reset assert for Airoha EN7581 SoC (Lorenzo

Merge tag 'drm-next-2025-03-28' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

sound updates for 6.15-rc1
We've received lots of commits at this time, as a result of various
cleanup and refactoring works as well as a few new drivers and the
generic SoundWire support. Most of changes are device-specific,
little about the core changes. Some highlights below:
Core:
* A couple of (rather minor) race fixes in ALSA sequencer code
* A regression fix in ALSA timer code that may lead to a deadlock
ASoC:
* A large series of code conversion to use modern terminology for the
clocking configuration
* Conversions of PM ops with the modern macros in all ASoC drivers
* Clarification of the control operations
* Prepartory work for more generic SoundWire SCDA controls
* Support for AMD ACP 7.x, AWINC WM88166, Everest ES8388, Intel AVS
PEAKVOL and GAIN DSP modules Mediatek MT8188 DMIC, NXP i.MX95,
nVidia Tegra interconnects, Rockchip RK3588 S/PDIF, Texas
Instruments SN012776 and TAS5770L, and Wolfson WM8904 DMICs
Others:
* Conversions of PM ops with the modern macros in the rest drivers
* USB-audio quirks and fixes for Presonus Studio, DJM-A9, CME
* HD-audio quirks and fixes ASUS, HP, Lenovo, and others
Note that the PR contains some changes from the tip tree for AMD code,
and it might give some merge conflict due to the rebase afterwards.

Power management updates for 6.15-rc1
- Manage sysfs attributes and boost frequencies efficiently from
cpufreq core to reduce boilerplate code in drivers (Viresh Kumar).
- Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider,
Dhananjay Ugwekar, Imran Shaik, zuoqian).
- Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky
Bai).
- cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski).
- Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng).
- Optimize the amd-pstate driver to avoid cases where call paths end
up calling the same writes multiple times and needlessly caching
variables through code reorganization, locking overhaul and tracing
adjustments (Mario Limonciello, Dhananjay Ugwekar).
- Make it possible to avoid enabling capacity-aware scheduling (CAS) in
the intel_pstate driver and relocate a check for out-of-band (OOB)
platform handling in it to make it detect OOB before checking HWP
availability (Rafael Wysocki).
- Fix dbs_update() to avoid inadvertent conversions of negative integer
values to unsigned int which causes CPU frequency selection to be
inaccurate in some cases when the "conservative" cpufreq governor is
in use (Jie Zhan).
- Update the handling of the most recent idle intervals in the menu
cpuidle governor to prevent useful information from being discarded
by it in some cases and improve the prediction accuracy (Rafael
Wysocki).
- Make it possible to tell the intel_idle driver to ignore its built-in
table of idle states for the given processor, clean up the handling
of auto-demotion disabling on Baytrail and Cherrytrail chips in it,
and update its MAINTAINERS entry (David Arcari, Artem Bityutskiy,
Rafael Wysocki).
- Make some cpuidle drivers use for_each_present_cpu() instead of
for_each_possible_cpu() during initialization to avoid issues
occurring when nosmp or maxcpus=0 are used (Jacky Bai).
- Clean up the Energy Model handling code somewhat (Rafael Wysocki).
- Use kfree_rcu() to simplify the handling of runtime Energy Model
updates (Li RongQing).
- Add an entry for the Energy Model framework to MAINTAINERS as
properly maintained (Lukasz Luba).
- Address RCU-related sparse warnings in the Energy Model code (Rafael
Wysocki).
- Remove ENERGY_MODEL dependency on SMP and allow it to be selected
when DEVFREQ is set without CPUFREQ so it can be used on a wider
range of systems (Jeson Gao).
- Unify error handling during runtime suspend and runtime resume in the
core to help drivers to implement more consistent runtime PM error
handling (Rafael Wysocki).
- Drop a redundant check from pm_runtime_force_resume() and rearrange
documentation related to __pm_runtime_disable() (Rafael Wysocki).
- Rework the handling of the "smart suspend" driver flag in the PM core

Pull power management updates from Rafael Wysocki:
"These are dominated by cpufreq updates which in turn are dominated by
updates related to boost support in the core and drivers and
amd-pstate driver optimizations.
Apart from the above, there are some cpuidle updates including a
rework of the most recent idle intervals handling in the venerable
menu governor that leads to significant improvements in some
performance benchmarks, as the governor is now more likely to predict
a shorter idle duration in some cases, and there are updates of the
core device power management code, mostly related to system suspend
and resume, that should help to avoid potential issues arising when
the drivers of devices depending on one another want to use different
optimizations.
There is also a usual collection of assorted fixes and cleanups,
including removal of some unused code.
Specifics:
- Manage sysfs attributes and boost frequencies efficiently from
cpufreq core to reduce boilerplate code in drivers (Viresh Kumar)
- Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider,
Dhananjay Ugwekar, Imran Shaik, zuoqian)
- Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky
Bai)
- cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski)
- Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng)
- Optimize the amd-pstate driver to avoid cases where call paths end
up calling the same writes multiple times and needlessly caching
variables through code reorganization, locking overhaul and tracing
adjustments (Mario Limonciello, Dhananjay Ugwekar)
- Make it possible to avoid enabling capacity-aware scheduling (CAS)
in the intel_pstate driver and relocate a check for out-of-band
(OOB) platform handling in it to make it detect OOB before checking
HWP availability (Rafael Wysocki)
- Fix dbs_update() to avoid inadvertent conversions of negative
integer values to unsigned int which causes CPU frequency selection
to be inaccurate in some cases when the "conservative" cpufreq
governor is in use (Jie Zhan)
- Update the handling of the most recent idle intervals in the menu
cpuidle governor to prevent useful information from being discarded
by it in some cases and improve the prediction accuracy (Rafael
Wysocki)
- Make it possible to tell the intel_idle driver to ignore its
built-in table of idle states for the given processor, clean up the
handling of auto-demotion disabling on Baytrail and Cherrytrail
chips in it, and update its MAINTAINERS entry (David Arcari, Artem
Bityutskiy, Rafael Wysocki)
- Make some cpuidle drivers use for_each_present_cpu() instead of
for_each_possible_cpu() during initialization to avoid issues
occurring when nosmp or maxcpus=0 are used (Jacky Bai)
- Clean up the Energy Model handling code somewhat (Rafael Wysocki)
- Use kfree_rcu() to simplify the handling of runtime Energy Model
updates (Li RongQing)
- Add an entry for the Energy Model framework to MAINTAINERS as
properly maintained (Lukasz Luba)
- Address RCU-related sparse warnings in the Energy Model code
(Rafael Wysocki)
- Remove ENERGY_MODEL dependency on SMP and allow it to be selected
when DEVFREQ is set without CPUFREQ so it can be used on a wider
range of systems (Jeson Gao)
- Unify error handling during runtime suspend and runtime resume in
the core to help drivers to implement more consistent runtime PM
error handling (Rafael Wysocki)
- Drop a redundant check from pm_runtime_force_resume() and rearrange
documentation related to __pm_runtime_disable() (Rafael Wysocki)
- Rework the handling of the "smart suspend" driver flag in the PM
core to avoid issues hat may occur when drivers using it depend on
some other drivers and clean up the related PM core code (Rafael
Wysocki, Colin Ian King)
- Fix the handling of devices with the power.direct_complete flag set
if device_suspend() returns an error for at least one device to
avoid situations in which some of them may not be resumed (Rafael
Wysocki)
- Use mutex_trylock() in hibernate_compressor_param_set() to avoid a

A treewide hrtimer timer cleanup
hrtimers are initialized with hrtimer_init() and a subsequent store to the callback pointer. This turned out to be suboptimal for the upcoming Rust integration and is obviously a silly implementation to begin with. This cleanup replaces the hrtimer_init(T); T->function = cb; sequence with hrtimer_setup(T, cb); The conversion was done with Coccinelle and a few manual fixups. Once the conversion has completely landed in mainline, hrtimer_init() will be removed and the hrtimer::function becomes a private member. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmff5jQTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoVvRD/wKtuwmiA66NJFgXC0qVq82A6fO3bY8 GBdbfysDJIbqGu5PTcULTbJ8qkqv3jeLUv6CcXvS4sZ7y/uJQl2lzf8yrD/0bbwc rLI6sHiPSZmK93kNVN4X5H7kvt7cE/DYC9nnEOgK3BY5FgKc4n9887d4aVBhL8Lv ODwVXvZ+xi351YCj7qRyPU24zt/p4tkkT1o2k4a0HBluqLI0D+V20fke9IERUL8r d1uWKlcn0TqYDesE8HXKIhbst3gx52rMJrXBJDHwFmG6v8Pj1fkTXCVpPo8QcBz8 OTVkpomN9f/Tx4+GZwhZOF86LhLL3OhxD6pT7JhFCXdmSGv+Ez8uyk1YZysM/XpV Juy/1yAcBpDIDkmhMFGdAAn48Nn9Fotty0r4je60zSEp1d/4QMXcFme29qr2JTUE iWnQ/HD6DxUjVHqy7CYvvo26Xegg1C7qgyOVt4PYZwAM1VKF5P3kzYTb4SAdxtop Tpji1sfW9QV08jqMNo6XntD32DSP9S2HqjO9LwBw700jnx2jjJ35fcJs6iodMOUn gckIZLMn3L0OoglPdyA5O7SNTbKE7aFiRKdnT/cJtR3Fa39Qu27CwC5gfiyuie9I Q+LG8GLuYSBHXAR+PBK4GWlzJ7Dn8k3eqmbnLeKpRMsU6ZzcttgA64xhaviN2wN0 iJbvLJeisXr3GA== =bYAX -----END PGP SIGNATURE----- Merge tag 'timers-cleanups-2025-03-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer cleanups from Thomas Gleixner: "A treewide hrtimer timer cleanup hrtimers are initialized with hrtimer_init() and a subsequent store to the callback pointer.
