If irq_domain_translate_twocell() sets "hwirq" to >= MCHP_EIC_NIRQ (2) then
it results in an out of bounds access.
The code checks for invalid values, but doesn't set the error code. Return
-EINVAL in that case, instead of returning success.

Pull pin control updates from Linus Walleij:
"The technical details below. For me the CIX Semi and Axis
Communications ARTPEC-9 SoCs were the most interesting new drivers in
this merge window.
Core changes:
- Handle per-direction skew control in the generic pin config
- Drop the pointless subsystem boilerplate banner message during
boot. Less noise in the console. It's available as debug message if
someone really want it
New drivers:
- Samsung Exynos 8890 SoC support
- Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.
These guys literally live next door to me, ARTPEC spells out "Axis
Real-Time Picture Encoding Chip" and is tailored for camera image
streams and is something they have evolved for a quarter of a
century
- Mediatek MT6878 SoC support
- Qualcomm Glymur PMIC support (mostly just compatible strings)

Improvements:
- Improvements for ST Microelectronics STM32 handling of skew
settings so input and output can have different skew settings
- A whole bunch of device tree binding cleanups: Marvell Armada and
Berlin, Actions Semiconductor S700 and S900, Broadcom Northstar 2
(NS2), Bitmain BM1880 and Spreadtrum SC9860 are moved over to
schema"

This commit addresses two issues causing i2c detect to fail.
The identified issues are:
1. Incorrect error handling for BED (Bus Error No ACK/NAK):
Before this commit, Both ALD (Arbitration Loss Detected) and
BED returned -EAGAIN.
2. Missing interrupt status clear after initialization in xfer():
On the K1 SoC, simply fixing the first issue changed the error
from -EAGAIN to -ETIMEOUT. Through tracing, it was determined that
this is likely due to MSD (Master Stop Detected) latency issues.
That means the MSD bit in the ISR may still be set on the next transfer.
As a result, the controller won't work — we can see from the scope that
it doesn't issue any signal.
(This only occurs during rapid consecutive I2C transfers.
That explains why the issue only shows up with i2cdetect.)
With these two fixes, i2c device detection now functions correctly on the K1 SoC.

In i2c_amd_probe(), amd_mp2_find_device() utilizes
driver_find_next_device() which internally calls driver_find_device()
to locate the matching device. driver_find_device() increments the
reference count of the found device by calling get_device(), but
amd_mp2_find_device() fails to call put_device() to decrement the
reference count before returning. This results in a reference count
leak of the PCI device each time i2c_amd_probe() is executed, which
may prevent the device from being properly released and cause a memory
leak.
Found by code review.

higher in the diffstat this time because they added quite a few clks
all over the place.
Overall it is a semi-quiet release that has some new clk drivers and
the usual fixes for clock data that was wrong or missing and
non-critical cleanups that plug error paths or fix typos.
New Drivers:
- Qualcomm IPQ5424 Network Subsystem Clock Controller
- Qualcomm SM8750 Video Clock Controller
- Rockchip RV1126B and RK3506 clock drivers
- i.MX8ULP SIM LPAV clock driver
- Samsung ACPM (firmware interface) clock driver

The for_each_child_of_node() macro automatically manages device node
reference counts during normal iteration. However, when breaking out
of the loop early with return, the current iteration's node is not
automatically released, leading to a reference count leak.
Fix this by adding of_node_put(child) before returning from the loop
when emc2305_set_single_tz() fails.
This issue could lead to memory leaks over multiple probe cycles.

The macro FAN_FROM_REG evaluates its arguments multiple times. When used
in lockless contexts involving shared driver data, this leads to
Time-of-Check to Time-of-Use (TOCTOU) race conditions, potentially
causing divide-by-zero errors.
Convert the macro to a static function. This guarantees that arguments
are evaluated only once (pass-by-value), preventing the race
conditions.
Additionally, in store_fan_div, move the calculation of the minimum
limit inside the update lock. This ensures that the read-modify-write
sequence operates on consistent data.
Adhere to the principle of minimal changes by only converting macros
that evaluate arguments multiple times and are used in lockless
contexts.

is a major new feature targeted at cloud environments. Quoting the
cover letter:
This series introduces the Live Update Orchestrator, a kernel
subsystem designed to facilitate live kernel updates using a
kexec-based reboot. This capability is critical for cloud
environments, allowing hypervisors to be updated with minimal
downtime for running virtual machines. LUO achieves this by
preserving the state of selected resources, such as memory,
devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving
memfd file descriptors, which allows critical in-memory data, such
as guest RAM or any other large memory region, to be maintained in
RAM across the kexec reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.

Pull PCIe Link Encryption and Device Authentication from Dan Williams:
"New PCI infrastructure and one architecture implementation for PCIe
link encryption establishment via platform firmware services.
This work is the result of multiple vendors coming to consensus on
some core infrastructure (thanks Alexey, Yilun, and Aneesh!), and
three vendor implementations, although only one is included in this
pull. The PCI core changes have an ack from Bjorn, the crypto/ccp/
changes have an ack from Tom, and the iommu/amd/ changes have an ack
from Joerg.
PCIe link encryption is made possible by the soup of acronyms
mentioned in the shortlog below. Link Integrity and Data Encryption
(IDE) is a protocol for installing keys in the transmitter and
receiver at each end of a link. That protocol is transported over Data
Object Exchange (DOE) mailboxes using PCI configuration requests.
The aspect that makes this a "platform firmware service" is that the
key provisioning and protocol is coordinated through a Trusted
Execution Envrionment (TEE) Security Manager (TSM). That is either
firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor
software (Intel TDX Connect / ARM CCA) running in a protected CPU
mode.
Now, the only reason to ask a TSM to run this protocol and install the
keys rather than have a Linux driver do the same is so that later, a
confidential VM can ask the TSM directly "can you certify this
device?".
That precludes host Linux from provisioning its own keys, because host
Linux is outside the trust domain for the VM. It also turns out that
all architectures, save for one, do not publish a mechanism for an OS
to establish keys in the root port. So "TSM-established link
encryption" is the only cross-architecture path for this capability
for the foreseeable future.
This unblocks the other arch implementations to follow in v6.20/v7.0,
once they clear some other dependencies, and it unblocks the next
phase of work to implement the end-to-end flow of confidential device
assignment. The PCIe specification calls this end-to-end flow Trusted
Execution Environment (TEE) Device Interface Security Protocol
(TDISP).
In the meantime, Linux gets a link encryption facility which has
practical benefits along the same lines as memory encryption. It
authenticates devices via certificates and may protect against
interposer attacks trying to capture clear-text PCIe traffic.
Summary:
- Introduce the PCI/TSM core for the coordination of device
authentication, link encryption and establishment (IDE), and later
management of the device security operational states (TDISP).
Notify the new TSM core layer of PCI device arrival and departure
- Add a low level TSM driver for the link encryption establishment
capabilities of the AMD SEV-TIO architecture
- Add a library of helpers TSM drivers to use for IDE establishment
and the DOE transport
- Add skeleton support for 'bind' and 'guest_request' operations in
support of TDISP"

Pull nvdimm updates from Ira Weiny:
"These are mainly bug fixes and code updates.
There is a new feature to divide up memmap= carve outs and a fix
caught in linux-next for that patch. Managing memmap memory on the fly
for multiple VM's was proving difficult and Mike provided a driver
which allows for the memory to be better manged.
Summary:
- Allow exposing RAM carveouts as NVDIMM DIMM devices
- Prevent integer overflow in ramdax_get_config_data()
- Replace use of system_wq with system_percpu_wq
- Documentation: btt: Unwrap bit 31-30 nested table

"Rust module parameter support:
- Add Rust module parameter support, enabling Rust kernel modules to
declare and use module parameters. The rust_minimal sample module
demonstrates this, and the rust null block driver will be the first

under the modules subsystem as agreed between the Rust and modules
maintainers.
Hardening:
- Add compile-time check for embedded NUL characters in MODULE_*()

bypass license enforcement (LWN article from 2003):

Pull SoC devicetree updates from Arnd Bergmann:
"Three new SoCs got added in existing arm64 chip families:
- Renesas R-Car X5H (R8A78000) is a new generation of automotive
SoCs, based on 16 Cortex-A720 (Armv9.2) cores, which makes the the
currently highest-perforance embedded SoC.
- TI AM62L is a new variant of the AM62 family of industrial SoCs,
this one comes without a GPU.
- Qualcomm MSM8937 (Snapdragon 430) is an older mobile phone chip
based on Cortex-A53, and closely related to MSM8917 (Snapdragn
425), which we already support.
In addition, there are a good number of newly supported machines
across SoC families:
- Two Aspeed AST2600 (Cortex-A7) based BMC setups for large servers
- Mobile Phones and tables based on Mediatek MT6582, Nvidia Tegra124,
Qualcomm MSM8937 and Qualcomm MSM8939,
- Two Laptops based on Qualcomm SoCs: one using the older sdm850, the
other using x1p42100.
- One Router based on Rockchips RK3568
- 24 variants of the Enclustra Mercury system-on-module, all based on
32-bit Intel/Altera SocFPGA chips, plus two boards using 64-bit
SocFPGA Agilex chips..
- 30 industrial/embedded boards and single-board computers, using
various chips from NXP, Rockchips, Mediatek, TI, Amlogic, Qualcomm,
Spacemit, and Starfive.

Pull KVM updates from Paolo Bonzini:
"ARM:
- Support for userspace handling of synchronous external aborts
(SEAs), allowing the VMM to potentially handle the abort in a
non-fatal manner
- Large rework of the VGIC's list register handling with the goal of
supporting more active/pending IRQs than available list registers
in hardware. In addition, the VGIC now supports EOImode==1 style
deactivations for IRQs which may occur on a separate vCPU than the
one that acked the IRQ
- Support for FEAT_XNX (user / privileged execute permissions) and
FEAT_HAF (hardware update to the Access Flag) in the software page
table walkers and shadow MMU
- Allow page table destruction to reschedule, fixing long
need_resched latencies observed when destroying a large VM
- Minor fixes to KVM and selftests
Loongarch:
- Get VM PMU capability from HW GCFG register
- Add AVEC basic support
- Use 64-bit register definition for EIOINTC
- Add KVM timer test cases for tools/selftests
RISC/V:
- SBI message passing (MPXY) support for KVM guest
- Give a new, more specific error subcode for the case when in-kernel
AIA virtualization fails to allocate IMSIC VS-file
- Support KVM_DIRTY_LOG_INITIALLY_SET, enabling dirty log gradually
in small chunks
- Fix guest page fault within HLV* instructions
- Flush VS-stage TLB after VCPU migration for Andes cores
s390:
- Always allocate ESCA (Extended System Control Area), instead of
starting with the basic SCA and converting to ESCA with the
addition of the 65th vCPU. The price is increased number of exits
(and worse performance) on z10 and earlier processor; ESCA was
introduced by z114/z196 in 2010
- VIRT_XFER_TO_GUEST_WORK support
- Operation exception forwarding support
- Cleanups
x86:
- Skip the costly "zap all SPTEs" on an MMIO generation wrap if MMIO
SPTE caching is disabled, as there can't be any relevant SPTEs to
zap
- Relocate a misplaced export
- Fix an async #PF bug where KVM would clear the completion queue
when the guest transitioned in and out of paging mode, e.g. when
handling an SMI and then returning to paged mode via RSM
- Leave KVM's user-return notifier registered even when disabling
virtualization, as long as kvm.ko is loaded. On reboot/shutdown,
keeping the notifier registered is ok; the kernel does not use the
MSRs and the callback will run cleanly and restore host MSRs if the
CPU manages to return to userspace before the system goes down
- Use the checked version of {get,put}_user()
- Fix a long-lurking bug where KVM's lack of catch-up logic for
periodic APIC timers can result in a hard lockup in the host
- Revert the periodic kvmclock sync logic now that KVM doesn't use a
clocksource that's subject to NTP corrections
- Clean up KVM's handling of MMIO Stale Data and L1TF, and bury the
latter behind CONFIG_CPU_MITIGATIONS
- Context switch XCR0, XSS, and PKRU outside of the entry/exit fast
path; the only reason they were handled in the fast path was to
paper of a bug in the core #MC code, and that has long since been
fixed
- Add emulator support for AVX MOV instructions, to play nice with
emulated devices whose guest drivers like to access PCI BARs with
large multi-byte instructions
x86 (AMD):
- Fix a few missing "VMCB dirty" bugs
- Fix the worst of KVM's lack of EFER.LMSLE emulation
- Add AVIC support for addressing 4k vCPUs in x2AVIC mode
- Fix incorrect handling of selective CR0 writes when checking
intercepts during emulation of L2 instructions
- Fix a currently-benign bug where KVM would clobber SPEC_CTRL[63:32]
on VMRUN and #VMEXIT
- Fix a bug where KVM corrupt the guest code stream when re-injecting
a soft interrupt if the guest patched the underlying code after the
VM-Exit, e.g. when Linux patches code with a temporary INT3
- Add KVM_X86_SNP_POLICY_BITS to advertise supported SNP policy bits
to userspace, and extend KVM "support" to all policy bits that
don't require any actual support from KVM
x86 (Intel):
- Use the root role from kvm_mmu_page to construct EPTPs instead of
the current vCPU state, partly as worthwhile cleanup, but mostly to
pave the way for tracking per-root TLB flushes, and elide EPT
flushes on pCPU migration if the root is clean from a previous
flush
- Add a few missing nested consistency checks
- Rip out support for doing "early" consistency checks via hardware
as the functionality hasn't been used in years and is no longer
useful in general; replace it with an off-by-default module param
to WARN if hardware fails a check that KVM does not perform
- Fix a currently-benign bug where KVM would drop the guest's
SPEC_CTRL[63:32] on VM-Enter
- Misc cleanups
- Overhaul the TDX code to address systemic races where KVM (acting
on behalf of userspace) could inadvertantly trigger lock contention
in the TDX-Module; KVM was either working around these in weird,
ugly ways, or was simply oblivious to them (though even Yan's
devilish selftests could only break individual VMs, not the host
kernel)
- Fix a bug where KVM could corrupt a vCPU's cpu_list when freeing a
TDX vCPU, if creating said vCPU failed partway through
- Fix a few sparse warnings (bad annotation, 0 != NULL)
- Use struct_size() to simplify copying TDX capabilities to userspace
- Fix a bug where TDX would effectively corrupt user-return MSR
values if the TDX Module rejects VP.ENTER and thus doesn't clobber
host MSRs as expected
Selftests:
- Fix a math goof in mmu_stress_test when running on a single-CPU
system/VM
- Forcefully override ARCH from x86_64 to x86 to play nice with
specifying ARCH=x86_64 on the command line
- Extend a bunch of nested VMX to validate nested SVM as well
- Add support for LA57 in the core VM_MODE_xxx macro, and add a test
to verify KVM can save/restore nested VMX state when L1 is using
5-level paging, but L2 is not
- Clean up the guest paging code in anticipation of sharing the core
logic for nested EPT and nested NPT
guest_memfd:
- Add NUMA mempolicy support for guest_memfd, and clean up a variety
of rough edges in guest_memfd along the way
- Define a CLASS to automatically handle get+put when grabbing a
guest_memfd from a memslot to make it harder to leak references
- Enhance KVM selftests to make it easer to develop and debug
selftests like those added for guest_memfd NUMA support, e.g. where
test and/or KVM bugs often result in hard-to-debug SIGBUS errors
- Misc cleanups

workqueue for irqfd cleanup
- Fix a goof in the dirty ring documentation
- Fix choice of target for directed yield across different calls to

Root partitions running on MSHV currently attempt ACPI power-off, which
MSHV intercepts and triggers a Machine Check Exception (MCE), leading
to a kernel panic.
Root partitions panic with a trace similar to:
[ 81.306348] reboot: Power down
[ 81.314709] mce: [Hardware Error]: CPU 0: Machine Check Exception: 4 Bank 0: b2000000c0060001

[ 81.314716] mce: [Hardware Error]: Machine check: Processor context corrupt
[ 81.314717] Kernel panic - not syncing: Fatal machine check
To avoid this, configure the sleep state in the hypervisor and invoke
the HVCALL_ENTER_SLEEP_STATE hypercall as the final step in the shutdown
sequence. This ensures a clean and safe shutdown of the root partition.

Introduce support for movable memory regions in the Hyper-V root partition
driver to improve memory management flexibility and enable advanced use
cases such as dynamic memory remapping.
Mirror the address space between the Linux root partition and guest VMs
using HMM. The root partition owns the memory, while guest VMs act as
devices with page tables managed via hypercalls. MSHV handles VP intercepts
by invoking hmm_range_fault() and updating SLAT entries. When memory is
reclaimed, HMM invalidates the relevant regions, prompting MSHV to clear
SLAT entries; guest VMs will fault again on access.
Integrate mmu_interval_notifier for movable regions, implement handlers for
HMM faults and memory invalidation, and update memory region mapping logic
to support movable regions.
While MMU notifiers are commonly used in virtualization drivers, this
implementation leverages HMM (Heterogeneous Memory Management) for its
specialized functionality. HMM provides a framework for mirroring,
invalidation, and fault handling, reducing boilerplate and improving
maintainability compared to generic MMU notifiers.

Introduce kref-based reference counting and spinlock protection for
memory regions in Hyper-V partition management. This change improves
memory region lifecycle management and ensures thread-safe access to the
region list.
Previously, the regions list was protected by the partition mutex.
However, this approach is too heavy for frequent fault and invalidation
operations. Finer grained locking is now used to improve efficiency and
concurrency.
This is a precursor to supporting movable memory regions. Fault and
invalidation handling for movable regions will require safe traversal of
the region list and holding a region reference while performing
invalidation or fault operations.

The previous code assumed that if a region's first page was huge, the
entire region consisted of huge pages and stored this in a large_pages
flag. This premise is incorrect not only for movable regions (where
pages can be split and merged on invalidate callbacks or page faults),
but even for pinned regions: THPs can be split and merged during
allocation, so a large, pinned region may contain a mix of huge and
regular pages.
This change removes the large_pages flag and replaces region-wide
assumptions with per-chunk inspection of the actual page size when
mapping, unmapping, sharing, and unsharing. This makes huge page
handling correct for mixed-page regions and avoids relying on stale
metadata that can easily become invalid as memory is remapped.

Pull persistent dentry infrastructure and conversion from Al Viro:
"Some filesystems use a kinda-sorta controlled dentry refcount leak to
pin dentries of created objects in dcache (and undo it when removing
those). A reference is grabbed and not released, but it's not actually
_stored_ anywhere.
That works, but it's hard to follow and verify; among other things, we
have no way to tell _which_ of the increments is intended to be an
unpaired one. Worse, on removal we need to decide whether the
reference had already been dropped, which can be non-trivial if that
removal is on umount and we need to figure out if this dentry is
pinned due to e.g. unlink() not done. Usually that is handled by using
kill_litter_super() as ->kill_sb(), but there are open-coded special
cases of the same (consider e.g. /proc/self).
Things get simpler if we introduce a new dentry flag
(DCACHE_PERSISTENT) marking those "leaked" dentries. Having it set
claims responsibility for +1 in refcount.
The end result this series is aiming for:
- get these unbalanced dget() and dput() replaced with new primitives
that would, in addition to adjusting refcount, set and clear
persistency flag.
- instead of having kill_litter_super() mess with removing the
remaining "leaked" references (e.g. for all tmpfs files that hadn't
been removed prior to umount), have the regular
shrink_dcache_for_umount() strip DCACHE_PERSISTENT of all dentries,
dropping the corresponding reference if it had been set. After that
kill_litter_super() becomes an equivalent of kill_anon_super().
Doing that in a single step is not feasible - it would affect too many
places in too many filesystems. It has to be split into a series.
This work has really started early in 2024; quite a few preliminary
pieces have already gone into mainline. This chunk is finally getting
to the meat of that stuff - infrastructure and most of the conversions
to it.
Some pieces are still sitting in the local branches, but the bulk of
that stuff is here"

Two fixes for Exynos PMU (Power Management Unit) driver:
1. Silence lockdep warning being actually a false positive, but quite
disturbing during testing. Issue was introduced in v6.18.
2. Drop device refcount when requesting device regmap with
exynos_get_pmu_regmap_by_phandle(). Issue was introduced much
earlier (around v6.9), with code being rewritten in between.

min_t(unsigned int, a, b) casts an 'unsigned long' to 'unsigned int'.
Use min(a, b) instead as it promotes any 'unsigned int' to 'unsigned long'
and so cannot discard significant bits.
In this case the 'unsigned long' value is small enough that the result
is ok.
Detected by an extra check added to min_t().

tpm2_read_public() has some rudimentary range checks but the function does
not ensure that the response buffer has enough bytes for the full TPMT_HA
payload.
Re-implement the function with necessary checks and validation, and return
name and name size for all handle types back to the caller.

'name_size' does not have any range checks, and it just directly indexes
with TPM_ALG_ID, which could lead into memory corruption at worst.
Address the issue by only processing known values and returning -EINVAL for
unrecognized values.
Make also 'tpm_buf_append_name' and 'tpm_buf_fill_hmac_session' fallible so
that errors are detected before causing any spurious TPM traffic.
End also the authorization session on failure in both of the functions, as
the session state would be then by definition corrupted.

Pull iommufd updates from Jason Gunthorpe:
"This is a pretty consequential cycle for iommufd, though this pull is
not too big. It is based on a shared branch with VFIO that introduces
VFIO_DEVICE_FEATURE_DMA_BUF a DMABUF exporter for VFIO device's MMIO
PCI BARs. This was a large multiple series journey over the last year
and a half.
Based on that work IOMMUFD gains support for VFIO DMABUF's in its
existing IOMMU_IOAS_MAP_FILE, which closes the last major gap to
support PCI peer to peer transfers within VMs.
In Joerg's iommu tree we have the "generic page table" work which aims
to consolidate all the duplicated page table code in every iommu
driver into a single algorithm. This will be used by iommufd to
implement unique page table operations to start adding new features
and improve performance.
In here:
- Expand IOMMU_IOAS_MAP_FILE to accept a DMABUF exported from VFIO.
This is the first step to broader DMABUF support in iommufd, right
now it only works with VFIO. This closes the last functional gap
with classic VFIO type 1 to safely support PCI peer to peer DMA by
mapping the VFIO device's MMIO into the IOMMU.
- Relax SMMUv3 restrictions on nesting domains to better support
qemu's sequence to have an identity mapping before the vSID is
established"

Pull VFIO updates from Alex Williamson:
- Move libvfio selftest artifacts in preparation of more tightly
coupled integration with KVM selftests (David Matlack)
- Fix comment typo in mtty driver (Chu Guangqing)
- Support for new hardware revision in the hisi_acc vfio-pci variant
driver where the migration registers can now be accessed via the PF.
When enabled for this support, the full BAR can be exposed to the
user (Longfang Liu)
- Fix vfio cdev support for VF token passing, using the correct size
for the kernel structure, thereby actually allowing userspace to
provide a non-zero UUID token. Also set the match token callback for
the hisi_acc, fixing VF token support for this this vfio-pci variant
driver (Raghavendra Rao Ananta)
- Introduce internal callbacks on vfio devices to simplify and
consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO
data, removing various ioctl intercepts with a more structured
solution (Jason Gunthorpe)
- Introduce dma-buf support for vfio-pci devices, allowing MMIO regions
to be exposed through dma-buf objects with lifecycle managed through
move operations. This enables low-level interactions such as a
vfio-pci based SPDK drivers interacting directly with dma-buf capable
RDMA devices to enable peer-to-peer operations. IOMMUFD is also now
able to build upon this support to fill a long standing feature gap
versus the legacy vfio type1 IOMMU backend with an implementation of
P2P support for VM use cases that better manages the lifecycle of the
P2P mapping (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy)
- Convert eventfd triggering for error and request signals to use RCU
mechanisms in order to avoid a 3-way lockdep reported deadlock issue
(Alex Williamson)
- Fix a 32-bit overflow introduced via dma-buf support manifesting with
large DMA buffers (Alex Mastro)
- Convert nvgrace-gpu vfio-pci variant driver to insert mappings on
fault rather than at mmap time. This conversion serves both to make
use of huge PFNMAPs but also to both avoid corrected RAS events
during reset by now being subject to vfio-pci-core's use of
unmap_mapping_range(), and to enable a device readiness test after
reset (Ankit Agrawal)
- Refactoring of vfio selftests to support multi-device tests and split
code to provide better separation between IOMMU and device objects.
This work also enables a new test suite addition to measure parallel
device initialization latency (David Matlack)

It turns out that the PCI driver for ccp is unconditionally built into the
kernel in the CONFIG_PCI=y case. This means that the new SEV-TIO support
needs an explicit dependency on PCI to avoid build errors when
CONFIG_CRYPTO_DEV_SP_PSP=y and CONFIG_PCI=n.

After commit 3225f52cde56 ("PCI/TSM: Establish Secure Sessions and Link
Encryption"), there is a Kconfig warning when selecting CONFIG_TSM
without CONFIG_VIRT_DRIVERS:
WARNING: unmet direct dependencies detected for TSM
Depends on [n]: VIRT_DRIVERS [=n]
Selected by [y]:
- PCI_TSM [=y] && PCI [=y]
CONFIG_TSM is defined in drivers/virt/coco/Kconfig but this Kconfig is
only sourced when CONFIG_VIRT_DRIVERS is enabled. Since this symbol is
hidden with no dependencies, it should be available without a symbol
that just enables a menu.
Move the sourcing of drivers/virt/coco/Kconfig outside of
CONFIG_VIRT_DRIVERS and wrap the other source statements in
drivers/virt/coco/Kconfig with CONFIG_VIRT_DRIVERS to ensure users do
not get any additional prompts while ensuring CONFIG_TSM is always
available to select. This complements commit 110c155e8a68 ("drivers/virt:
Drop VIRT_DRIVERS build dependency"), which addressed the build issue
that this Kconfig warning was pointing out.

- For devices with no driver or a driver that lacks power management,
save config state at hibernate so that state (not any earlier state
from enumeration, probe, or error recovery) will be restored when
resuming (Lukas Wunner)
- Save device config space on device addition, before driver binding,
so error recovery works more reliably (Lukas Wunner)
- Drop pci_save_state() from several drivers that no longer need it
since the PCI core always does it and pci_restore_state() no longer
invalidates the saved state (Lukas Wunner)
- Document use of pci_save_state() by drivers to capture the state
they want restored during error recovery (Lukas Wunner)
Power control:
- Add a struct pci_ops.assert_perst() function pointer to
assert/deassert PCIe PERST# and implement it for the qcom driver
(Krishna Chaitanya Chundru)
- Add DT binding and pwrctrl driver for the Toshiba TC9563 PCIe
switch, which must be held in reset after poweron so the pwrctrl
driver can configure the switch via I2C before bringing up the
links (Krishna Chaitanya Chundru)
Endpoint framework:
- Convert the endpoint doorbell test to use a threaded IRQ to fix a
'sleeping while atomic' issue (Bhanu Seshu Kumar Valluri)
- Add endpoint VNTB MSI doorbell support to reduce latency between
host and endpoint (Frank Li)
New native PCIe controller drivers:
- Add CIX Sky1 host controller DT binding and driver (Hans Zhang)
- Add NXP S32G host controller DT binding and driver (Vincent
Guittot)
- Add Renesas RZ/G3S host controller DT binding and driver (Claudiu
Beznea)
- Add SpacemiT K1 host controller DT binding and driver (Alex Elder)
Amlogic Meson PCIe controller driver:
- Update DT binding to name DBI region 'dbi', not 'elbi', and update
driver to support both (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Move struct pci_host_bridge allocation from pci_host_common_init()
to callers, which significantly simplifies pcie-apple (Marc
Zyngier)
Broadcom STB PCIe controller driver:
- Disable advertising ASPM L0s support correctly (Jim Quinlan)
- Add a panic/die handler to print diagnostic info in case PCIe
caused an unrecoverable abort (Jim Quinlan)
Cadence PCIe controller driver:
- Add module support for Cadence platform host and endpoint
controller driver (Manikandan K Pillai)
- Split headers into 'legacy' (LGA) and 'high perf' (HPA) to prepare
for new CIX Sky1 driver (Manikandan K Pillai)
MediaTek PCIe controller driver:
- Convert DT binding to YAML schema (Christian Marangi)
- Add Airoha AN7583 DT compatible and driver support (Christian
Marangi)
Qualcomm PCIe controller driver:
- Add Qualcomm Kaanapali to SM8550 DT binding (Qiang Yu)
- Add required 'power-domains' and 'resets' to qcom sa8775p, sc7280,
sc8280xp, sm8150, sm8250, sm8350, sm8450, sm8550, x1e80100 DT
schemas (Krzysztof Kozlowski)
- Look up OPP using both frequency and data rate (not just frequency)
so RPMh votes can account for both (Krishna Chaitanya Chundru)
Rockchip DesignWare PCIe controller driver:
- Add Rockchip RK3528 compatible strings in DT binding (Yao Zi)
STMicroelectronics STM32MP25 PCIe controller driver:
- Fix a race between link training and endpoint register
initialization (Christian Bruel)
- Align endpoint allocations to match the ATU requirements (Christian
Bruel)
Synopsys DesignWare PCIe controller driver:
- Clear L1 PM Substate Capability 'Supported' bits unless glue driver
says it's supported, which prevents users from enabling non-working
L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)
- Remove now-superfluous L1SS disable code from tegra194 (Bjorn
Helgaas)
- Configure L1SS support in dw-rockchip when DT says
'supports-clkreq' (Shawn Lin)
TI Keystone PCIe controller driver:
- Fail the probe instead of silently succeeding if ks_pcie_of_data
didn't specify Root Complex or Endpoint mode (Siddharth Vadapalli)
- Make keystone buildable as a loadable module, except on ARM32 where
hook_fault_code() is __init (Siddharth Vadapalli)"

Replace kcalloc with kvcalloc for allocation of the commands
array. Each command structure is 712 bytes. The array typically
exceeds a single page, and grows much larger with high queue depths

Replace kcalloc with kvcalloc for allocation of the commands and
responses arrays. Each command structure is 272 bytes and each
response structure is 672 bytes. These arrays typically exceed a
single page, and grow much larger with high queue depths
(e.g., commands >2MB, responses >170KB)

Many of the nvmet-fc log messages cannot print the device used, because
it's not there yet:
(NULL device *): {0:0} Association deleted
Use the pr_* macros consistently throughout the module and match the
output of the nvme-fc module.
Using port:association ids are more useful when debugging what's going
on, because these match now with the log entries from nvme-fc.

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver, lots of various updates to existing ones, some
refactoring support for new models and misc tweaks and fixes.
The biggest new feature in GPIO core is adding support for managed,
enable-counted sharing of GPIO pins, something that - until now - was
only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
which basically allowed drivers to "fight it out" for the descriptor
and provided no synchronization. It was enabled on Qualcomm platforms
(and thus is enabled on arm64 defconfig) and I plan on removing
GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
the new mechanism.
GPIO core:
- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot
enable counting) and enable it for Qualcomm platforms
- improve the software node GPIO lookup by using the fwnode
representation instead of the software node's name which was prone
to bugs (GPIO controllers don't have to use the software node's
name as their kernel label)
- remove the last user of legacy-of-mm-gpiochip.h and drop the header
- move closer to removing the legacy gpio_request_one() routine
- rename some symbols for consistency
- shrink GPIO printk() helpers by reusing existing code
- remove some redundant kernel messages
- use min() instead of min_t() in GPIO ACPI code
- use system_percpu_wq instead of system_wq in GPIO character device
code
New drivers:
- add a driver for the QIXIS FPGA GPIO controller
Driver improvements:
- use modernized variants of power management macros across a wide
array of drivers in order to avoid having to use the __maybe_unused
attribute
- convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
instead of the platform bus as they are not really described in
firmware
- use lock guards and update symbol prefixes in gpio-mmio
- support the bryx radio interface kit in gpio-mpsse + refactor the
driver
- use software nodes for configuring the reset-gpio driver, including
setting up the reference to the shared "reset" pin
- check and propagate the return value of gpiod_set_value() to
user-space in gpio-virtuser (this was previously not possible as
this function returned void)
- extend the gpio-regmap helper with more features (bypass cache for
aliased inputs, force writes for aliased data registers, add a new
configuration parameter)
- remove unneeded includes from gpio-aspeed and gpio-latch
- add support for Tegra410 to gpio-tegra186
- replace PCI-specific PM with generic device-level PM in gpio-bt8xx
- use dynamic GPIO range allocation in gpio-loongson-64bit
- improve handling of level-triggered interrupts in gpio-pca953x
- add suspend/resume support to gpio-fxl6408
- add support for more models to gpio-menz127
- optimize gpio-mvebu interrupt handling by avoiding unnecessary
calls to mvebu_gpio_irq_handler()
- make locking more consistent in gpio-grgpio
Device-tree bindings:
- document new NXP and Microchip models
Documentation:
- add a comprehensive compatibility and feature list for
gpio-pca953x, which is a great addition as it's probably the most
commonly used GPIO expander driver
- kernel-doc tweaks
Late fixes:
- use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson"

Pull firewire updates from Takashi Sakamoto:
"This includes two changes for core functions, which affects all use
cases of this subsystem:
- Handle per-device interoperability quirks
Some devices have quirks affecting interoperability. To identify
such quirks at an early stages of device detection, the step for
reading the configuration ROM contents has been changed. As a side
effect, the entire detection process is now performed at the basic
transaction speed (S100), without a trial to probe higher
supported speeds.
With this change, the following devices should now work with fewer
issues:
- TASCAM FW-1884, FW-1804, and FW-1082
- MOTU Audio Express
- Safer removals of host card
There was a race condition between host card removal and handling
of bus reset events in the workqueue. This appears to be a long
standing issue, and recent changes to use more workqueues escalate
it.
To solve it, a new callback has been added to the 1394 OHCI PCI
driver to unregister the interrupt sources and wait for workqueue
completions when removing a card instance"

Apparently this test is the only code that checks the return code from
pm_runtime_barrier(), and it turns out that's for good reason -- it's
inherently racy, and a bad idea. We're going to make
pm_runtime_barrier() return void, so prepare for that by dropping any
return code checks.
This resolves some test failures seen like the following:
[ 34.559694] # pm_runtime_error_test: EXPECTATION FAILED at drivers/base/power/runtime-test.c:177
[ 34.559694] Expected 1 == pm_runtime_barrier(dev), but

Pull spi updates from Mark Brown:
"This release is almost entirely new drivers, with a couple of small
changes in generic code.
The biggest individual update is a rename of the existing Microchip
driver and the addition of a new driver for the silicon SPI controller
in their PolarFire SoCs. The overlap between the soft IP supported by
the current driver and this new one is regrettably all in the IP and
not in the register interface offered to software.
- Add a time offset parameter for offloads, allowing them to be
defined in relation to each other. This is useful for IIO type
applcations where you trigger an operation then read the result
after a delay.
- Add a tracepoint for flash exec_ops, bringing the flash support
more in line with the debuggability of vanilla SPI.
- Support for Airoha EN7523, Arduino MCUs, Aspeed AST2700, Microchip
PolarFire SPI controllers, NXP i.MX51 ECSPI target mode, Qualcomm
IPQ5414 and IPQ5332, Renesas RZ/T2H, RZ/V2N and RZ/2NH and SpacemiT

Pull mtd updates from Miquel Raynal:
"Core MTD changes:
- We must ignore error -ENOENT from parsers on subpartitions which is
a legitimate return value
- PM support is added to the intel-dg driver
Raw NAND changes:
- The major change in this is the support for the Allwinner H616 NAND
controller, which lead to numerous changes and cleanups in the
driver.
- Another notable change in this driver is the use of field_get() and
field_prep(), but since the global support for this helpers is
going to be merged in the same release as we start using these
helpers, we undefine them in the first place to avoid warnings.
- Marvell drivers layout handling changes have also landed, they fix
previous definitions and abuses that have been made previously,
which implied to relax the ECC parameters validation in the core a
bit.
- The Cadence NAND controller driver gets NV-DDR interface support.
SPI NAND changes:
- Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added.
SPI NOR changes:
- Fix SMPT parsing for S25FS-S flash family. They report variable
dummy cycles for reads. This results in the default of 0 being
used. This works for other Infineon chips, but not for the S25FS-S
family. They need 8 dummy cycles. Add fixup hooks to specify that.
Also add fixup hooks to fix incorrect map ID data in SFDP.
- Add support for a bunch of Winbond flashes. Their block protection
information is not discoverable, so they need to have an entry in
the flash tables to describe that.
- Some cleanups for Micron flash support.
- Add support for Micron mt35xu01gbba.
- Some SPI controllers like the Intel one on the PCI bus do not
support the read CR opcode (0x35). Do not use the opcode if the
controller does not support it.
Aside from these main changes, there is the usual load of API updates,
kdoc fixes, potential memory leaks fixes, etc"

Add helpers to program the 3D LUT registers and arm them.
LUT_3D_READY in LUT_3D_CLT is cleared off by the HW once
the LUT buffer is loaded into it's internal working RAM.
So by the time we try to load/commit new values, we expect
it to be cleared off. If not, log an error and return
without writing new values. Do it only when writing with MMIO.
There is no way to read register within DSB execution.
v2:
- Add information regarding LUT_3D_READY to commit message (Jani)
- Log error instead of a drm_warn and return without committing changes
if 3DLUT HW is not ready to accept new values.
- Refactor intel_color_crtc_has_3dlut()
Also remove Gen10 check (Suraj)

Add a new helper function blk_rq_nr_bvec() that returns the number of
bvecs in a request. This count represents the number of iterations
rq_for_each_bvec() would perform on a request.
Drivers need to pre-allocate bvec arrays before iterating through
a request's bvecs. Currently, they manually count bvecs using
rq_for_each_bvec() in a loop, which is repetitive. The new helper
centralizes this logic.
This pattern exists in loop and zloop drivers, where multi-bio requests
require copying bvecs into a contiguous array before creating
an iov_iter for file operations.
Update loop and zloop drivers to use the new helper, eliminating
duplicate code.
This patch also provides a clear API to avoid any potential misuse of
blk_nr_phys_segments() for calculating the bvecs since, one bvec can
have more than one segments and use of blk_nr_phys_segments() can
lead to extra memory allocation :-
[ 6155.673749] nullb_bio: 128K bio as ONE bvec: sector=0, size=131072
[ 6155.673846] null_blk: #### null_handle_data_transfer:1375

Pull io_uring updates from Jens Axboe:
- Unify how task_work cancelations are detected, placing it in the
task_work running state rather than needing to check the task state
- Series cleaning up and moving the cancelation code to where it
belongs, in cancel.c
- Cleanup of waitid and futex argument handling
- Add support for mixed sized SQEs. 6.18 added support for mixed sized
CQEs, improving flexibility and efficiency of workloads that need big
CQEs. This adds similar support for SQEs, where the occasional need
for a 128b SQE doesn't necessitate having all SQEs be 128b in size
- Introduce zcrx and SQ/CQ layout queries. The former returns what zcrx
features are available. And both return the ring size information to
help with allocation size calculation for user provided rings like
IORING_SETUP_NO_MMAP and IORING_MEM_REGION_TYPE_USER
- Zcrx updates for 6.19. It includes a bunch of small patches,
IORING_REGISTER_ZCRX_CTRL and RQ flushing and David's work on sharing
zcrx b/w multiple io_uring instances
- Series cleaning up ring initializations, notable deduplicating ring
size and offset calculations. It also moves most of the checking
before doing any allocations, making the code simpler
- Add support for getsockname and getpeername, which is mostly a
trivial hookup after a bit of refactoring on the networking side

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Replace busylock at the Tx queuing layer with a lockless list.
Resulting in a 300% (4x) improvement on heavy TX workloads, sending
twice the number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue.
Normally we perform queue re-selection when flow comes out of idle,
but under extreme circumstances the flows may be constantly busy.
Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already
did for Rx skbs).
- Various data structure layout and prefetch optimizations from Eric.
- Remove ktime_get() from the recvmsg() fast path, ktime_get() is
sadly quite expensive on recent AMD machines.
- Extend threaded NAPI polling to allow the kthread busy poll for
packets.
- Make MPTCP use Rx backlog processing. This lowers the lock
pressure, improving the Rx performance.
- Support memcg accounting of MPTCP socket memory.
- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor
fit for modern container workloads, where limits are imposed using
cgroups.
- Improve heuristics for when to kick off AF_UNIX garbage collection.
- Allow users to control TCP SACK compression, and default to 33% of
RTT.
- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid
unnecessarily aggressive rcvbuf growth and overshot when the
connection RTT is low.
- Preserve skb metadata space across skb_push / skb_pull operations.
- Support for IPIP encapsulation in the nftables flowtable offload.
- Support appending IP interface information to ICMP messages (RFC
5837).
- Support setting max record size in TLS (RFC 8449).
- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.
- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.
- Let users configure the number of write buffers in SMC.
- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.
- Some conversions away from the crypto_ahash API, from Eric Biggers.
- Some preparations for slimming down struct page.
- YAML Netlink protocol spec for WireGuard.
- Add a tool on top of YAML Netlink specs/lib for reporting commonly
computed derived statistics and summarized system state.
Driver API:
- Add CAN XL support to the CAN Netlink interface.
- Add uAPI for reporting PHY Mean Square Error (MSE) diagnostics, as
defined by the OPEN Alliance's "Advanced diagnostic features for
100BASE-T1 automotive Ethernet PHYs" specification.
- Add DPLL phase-adjust-gran pin attribute (and implement it in
zl3073x).
- Refactor xfrm_input lock to reduce contention when NIC offloads
IPsec and performs RSS.
- Add info to devlink params whether the current setting is the
default or a user override. Allow resetting back to default.
- Add standard device stats for PSP crypto offload.
- Leverage DSA frame broadcast to implement simple HSR frame
duplication for a lot of switches without dedicated HSR offload.
- Add uAPI defines for 1.6Tbps link modes.
Device drivers:
- Add Motorcomm YT921x gigabit Ethernet switch support.
- Add MUCSE driver for N500/N210 1GbE NIC series.
- Convert drivers to support dedicated ops for timestamping control,
and away from the direct IOCTL handling. While at it support GET
operations for PHY timestamping.
- Add (and convert most drivers to) a dedicated ethtool callback for
reading the Rx ring count.

gpio gpiochip0: Static allocation of GPIO base is deprecated,
use dynamic allocation.
Set `sfp->gc.base = -1` to let the GPIO core dynamically allocate
the base number. This removes the warning and aligns the driver
with current GPIO guidelines.
Since the GPIO base is now allocated dynamically, remove `gc_base` field in
`struct jh7110_pinctrl_soc_info` and the associated `JH7110_SYS_GC_BASE`
and `JH7110_AON_GC_BASE` constants as they are no longer used anywhere
in the driver.
Tested on VisionFive 2 (JH7110 SoC).

pcs_pinconf_get() and pcs_pinconf_set() declare ret as unsigned int,
but assign it the return values of pcs_get_function() that may return
negative error codes. This causes negative error codes to be
converted to large positive values.
Change ret from unsigned int to int in both functions.

git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Add support for 'syn'.
Syn is a parsing library for parsing a stream of Rust tokens into a
syntax tree of Rust source code.
Currently this library is geared toward use in Rust procedural
macros, but contains some APIs that may be useful more generally.
'syn' allows us to greatly simplify writing complex macros such as
'pin-init' (Benno has already prepared the 'syn'-based version). We
will use it in the 'macros' crate too.
'syn' is the most downloaded Rust crate (according to crates.io),
and it is also used by the Rust compiler itself. While the amount
of code is substantial, there should not be many updates needed for
these crates, and even if there are, they should not be too big,
e.g. +7k -3k lines across the 3 crates in the last year.
'syn' requires two smaller dependencies: 'quote' and 'proc-macro2'.
I only modified their code to remove a third dependency
('unicode-ident') and to add the SPDX identifiers. The code can be
easily verified to exactly match upstream with the provided
scripts.
They are all licensed under "Apache-2.0 OR MIT", like the other
vendored 'alloc' crate we had for a while.
Please see the merge commit with the cover letter for more context.
- Allow 'unreachable_pub' and 'clippy::disallowed_names' for
doctests.
Examples (i.e. doctests) may want to do things like show public
items and use names such as 'foo'.
Nevertheless, we still try to keep examples as close to real code
as possible (this is part of why running Clippy on doctests is
important for us, e.g. for safety comments, which userspace Rust
does not support yet but we are stricter).
'kernel' crate:
- Replace our custom 'CStr' type with 'core::ffi::CStr'.
Using the standard library type reduces our custom code footprint,
and we retain needed custom functionality through an extension
trait and a new 'fmt!' macro which replaces the previous 'core'
import.
This started in 6.17 and continued in 6.18, and we finally land the
replacement now. This required quite some stamina from Tamir, who
split the changes in steps to prepare for the flag day change here.
- Replace 'kernel::c_str!' with C string literals.
C string literals were added in Rust 1.77, which produce '&CStr's
(the 'core' one), so now we can write:
c"hi"
instead of:
c_str!("hi")
- Add 'num' module for numerical features.
It includes the 'Integer' trait, implemented for all primitive
integer types.
It also includes the 'Bounded' integer wrapping type: an integer
value that requires only the 'N' least significant bits of the
wrapped type to be encoded:
// An unsigned 8-bit integer, of which only the 4 LSBs are used.
let v = Bounded::<u8, 4>::new::<15>();
assert_eq!(v.get(), 15);
'Bounded' is useful to e.g. enforce guarantees when working with
bitfields that have an arbitrary number of bits.
Values can also be constructed from simple non-constant expressions
or, for more complex ones, validated at runtime.
'Bounded' also comes with comparison and arithmetic operations
(with both their backing type and other 'Bounded's with a
compatible backing type), casts to change the backing type,
extending/shrinking and infallible/fallible conversions from/to
primitives as applicable.
- 'rbtree' module: add immutable cursor ('Cursor').
It enables to use just an immutable tree reference where
appropriate. The existing fully-featured mutable cursor is renamed
to 'CursorMut'.
kallsyms:
- Fix wrong "big" kernel symbol type read from procfs.
'pin-init' crate:
- A couple minor fixes (Benno asked me to pick these patches up for
him this cycle).
Documentation:
- Quick Start guide: add Debian 13 (Trixie).
Debian Stable is now able to build Linux, since Debian 13 (released
2025-08-09) packages Rust 1.85.0, which is recent enough.
We are planning to propose that the minimum supported Rust version
in Linux follows Debian Stable releases, with Debian 13 being the
first one we upgrade to, i.e. Rust 1.85.
MAINTAINERS:
- Add entry for the new 'num' module.
- Remove Alex as Rust maintainer: he hasn't had the time to
contribute for a few years now, so it is a no-op change in
practice.
And a few other cleanups and improvements"

Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
This change adds a new WQ_PERCPU flag to explicitly request
alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Allow creaing nbcon console drivers with an unsafe write_atomic()
callback that can only be called by the final nbcon_atomic_flush_unsafe().
Otherwise, the driver would rely on the kthread.
It is going to be used as the-best-effort approach for an
experimental nbcon netconsole driver, see
https://lore.kernel.org/r/20251121-nbcon-v1-2-503d17b2b4af@debian.org
Note that a safe .write_atomic() callback is supposed to work in NMI
context. But some networking drivers are not safe even in IRQ
context:
https://lore.kernel.org/r/oc46gdpmmlly5o44obvmoatfqo5bhpgv7pabpvb6sjuqioymcg@gjsma3ghoz35
In an ideal world, all networking drivers would be fixed first and
the atomic flush would be blocked only in NMI context. But it brings
the question how reliable networking drivers are when the system is
in a bad state. They might block flushing more reliable serial
consoles which are more suitable for serious debugging anyway.
- Allow to use the last 4 bytes of the printk ring buffer.
- Prevent queuing IRQ work and block printk kthreads when consoles are
suspended. Otherwise, they create non-necessary churn or even block
the suspend.
- Release console_lock() between each record in the kthread used for
legacy consoles on RT. It might significantly speed up the boot.
- Release nbcon context between each record in the atomic flush. It
prevents stalls of the related printk kthread after it has lost the
ownership in the middle of a record
- Add support for NBCON consoles into KDB
- Add %ptsP modifier for printing struct timespec64 and use it where
possible
- Misc code clean up

Pull arm64 FPSIMD on-stack buffer updates from Eric Biggers:
"This is a core arm64 change. However, I was asked to take this because
most uses of kernel-mode FPSIMD are in crypto or CRC code.
In v6.8, the size of task_struct on arm64 increased by 528 bytes due
to the new 'kernel_fpsimd_state' field. This field was added to allow
kernel-mode FPSIMD code to be preempted.
Unfortunately, 528 bytes is kind of a lot for task_struct. This
regression in the task_struct size was noticed and reported.
Recover that space by making this state be allocated on the stack at
the beginning of each kernel-mode FPSIMD section.
To make it easier for all the users of kernel-mode FPSIMD to do that
correctly, introduce and use a 'scoped_ksimd' abstraction"

Pull 'at_least' array size update from Eric Biggers:
"C supports lower bounds on the sizes of array parameters, using the
static keyword as follows: 'void f(int a[static 32]);'. This allows
the compiler to warn about a too-small array being passed.
As discussed, this reuse of the 'static' keyword, while standard, is a
bit obscure. Therefore, add an alias 'at_least' to compiler_types.h.
Then, add this 'at_least' annotation to the array parameters of
various crypto library functions"

Pull crypto library updates from Eric Biggers:
"This is the main crypto library pull request for 6.19. It includes:
- Add SHA-3 support to lib/crypto/, including support for both the
hash functions and the extendable-output functions. Reimplement the
existing SHA-3 crypto_shash support on top of the library.
This is motivated mainly by the upcoming support for the ML-DSA
signature algorithm, which needs the SHAKE128 and SHAKE256
functions. But even on its own it's a useful cleanup.
This also fixes the longstanding issue where the
architecture-optimized SHA-3 code was disabled by default.
- Add BLAKE2b support to lib/crypto/, and reimplement the existing
BLAKE2b crypto_shash support on top of the library.
This is motivated mainly by btrfs, which supports BLAKE2b
checksums. With this change, all btrfs checksum algorithms now have
library APIs. btrfs is planned to start just using the library
directly.
This refactor also improves consistency between the BLAKE2b code
and BLAKE2s code. And as usual, it also fixes the issue where the
architecture-optimized BLAKE2b code was disabled by default.
- Add POLYVAL support to lib/crypto/, replacing the existing POLYVAL
support in crypto_shash. Reimplement HCTR2 on top of the library.
This simplifies the code and improves HCTR2 performance. As usual,
it also makes the architecture-optimized code be enabled by
default. The generic implementation of POLYVAL is greatly improved
as well.
- Clean up the BLAKE2s code
- Add FIPS self-tests for SHA-1, SHA-2, and SHA-3"

Pull power management updates from Rafael Wysocki:
"There are quite a few interesting things here, including new hardware
support, new features, some bug fixes and documentation updates. In
addition, there are a usual bunch of minor fixes and cleanups all
over.
In the new hardware support category, there are intel_pstate and
intel_rapl driver updates to support new processors, Panther Lake,
Wildcat Lake, Noval Lake, and Diamond Rapids in the OOB mode, OPP and

the netlink support for the energy model management, support for
terminating system suspend via a wakeup event during the sync of file
systems, configurable number of hibernation compression threads, the
runtime PM auto-cleanup macros, and the "poweroff" PM event that is
expected to be used during system shutdown.
Bugs are mostly fixed in cpuidle governors, but there are also fixes
elsewhere, like in the amd-pstate cpufreq driver.
Documentation updates include, but are not limited to, a new doc on
debugging shutdown hangs, cross-referencing fixes and cleanups in the
intel_pstate documentation, and updates of comments in the core

Pull arm64 updates from Catalin Marinas:
"These are the arm64 updates for 6.19.
The biggest part is the Arm MPAM driver under drivers/resctrl/.
There's a patch touching mm/ to handle spurious faults for huge pmd
(similar to the pte version). The corresponding arm64 part allows us
to avoid the TLB maintenance if a (huge) page is reused after a write
fault. There's EFI refactoring to allow runtime services with
preemption enabled and the rest is the usual perf/PMU updates and
several cleanups/typos.
Summary:
Core features:
- Basic Arm MPAM (Memory system resource Partitioning And Monitoring)
driver under drivers/resctrl/ which makes use of the fs/rectrl/ API
Perf and PMU:
- Avoid cycle counter on multi-threaded CPUs
- Extend CSPMU device probing and add additional filtering support
for NVIDIA implementations
- Add support for the PMUs on the NoC S3 interconnect
- Add additional compatible strings for new Cortex and C1 CPUs
- Add support for data source filtering to the SPE driver
- Add support for i.MX8QM and "DB" PMU in the imx PMU driver
Memory managemennt:
- Avoid broadcast TLBI if page reused in write fault
- Elide TLB invalidation if the old PTE was not valid
- Drop redundant cpu_set_*_tcr_t0sz() macros
- Propagate pgtable_alloc() errors outside of __create_pgd_mapping()
- Propagate return value from __change_memory_common()
ACPI and EFI:
- Call EFI runtime services without disabling preemption
- Remove unused ACPI function
Miscellaneous:
- ptrace support to disable streaming on SME-only systems
- Improve sysreg generation to include a 'Prefix' descriptor
- Replace __ASSEMBLY__ with __ASSEMBLER__
- Align register dumps in the kselftest zt-test
- Remove some no longer used macros/functions
- Various spelling corrections"

Pull s390 updates from Heiko Carstens:
- Provide a new interface for dynamic configuration and deconfiguration
of hotplug memory, allowing with and without memmap_on_memory
support. This makes the way memory hotplug is handled on s390 much
more similar to other architectures
- Remove compat support. There shouldn't be any compat user space
around anymore, therefore get rid of a lot of code which also doesn't
need to be tested anymore
- Add stackprotector support. GCC 16 will get new compiler options,
which allow to generate code required for kernel stackprotector
support
- Merge pai_crypto and pai_ext PMU drivers into a new driver. This
removes a lot of duplicated code. The new driver is also extendable
and allows to support new PMUs
- Add driver override support for AP queues
- Rework and extend zcrypt and AP trace events to allow for tracing of
crypto requests
- Support block sizes larger than 65535 bytes for CCW tape devices
- Since the rework of the virtual kernel address space the module area
and the kernel image are within the same 4GB area. This eliminates
the need of weak per cpu variables. Get rid of
ARCH_MODULE_NEEDS_WEAK_PER_CPU
- Various other small improvements and fixes

Implement the SEV-TIO (Trusted I/O) firmware interface for PCIe TDISP
(Trust Domain In-Socket Protocol). This enables secure communication
between trusted domains and PCIe devices through the PSP (Platform
Security Processor).
The implementation includes:
- Device Security Manager (DSM) operations for establishing secure links
- SPDM (Security Protocol and Data Model) over DOE (Data Object Exchange)
- IDE (Integrity Data Encryption) stream management for secure PCIe
This module bridges the SEV firmware stack with the generic PCIe TSM
framework.
This is phase1 as described in Documentation/driver-api/pci/tsm.rst.
On AMD SEV, the AMD PSP firmware acts as TSM (manages the security/trust).
The CCP driver provides the interface to it and registers in the TSM
subsystem.
Detect the PSP support (reported via FEATURE_INFO + SNP_PLATFORM_STATUS)
and enable SEV-TIO in the SNP_INIT_EX call if the hardware supports TIO.
Implement SEV TIO PSP command wrappers in sev-dev-tio.c and store
the data in the SEV-TIO-specific structs.
Implement TSM hooks and IDE setup in sev-dev-tsm.c.
