Pull more power management updates from Rafael Wysocki:
"These are mostly fixes on top of the power management updates merged
recently in cpuidle governors, in the Intel RAPL power capping driver
and in the wake IRQ management code:
- Fix the handling of package-scope MSRs in the intel_rapl power
capping driver when called from the PMU subsystem and make it add
all package CPUs to the PMU cpumask to allow tools to read RAPL
events from any CPU in the package (Kuppuswamy Satharayananyan)
- Rework the invalid version check in the intel_rapl_tpmi power
capping driver to account for the fact that on partitioned systems,
multiple TPMI instances may exist per package, but RAPL registers
are only valid on one instance (Kuppuswamy Satharayananyan)
- Describe the new intel_idle.table command line option in the
admin-guide intel_idle documentation (Artem Bityutskiy)
- Fix a crash in the ladder cpuidle governor on systems with only one
(polling) idle state available by making the cpuidle core bypass
the governor in those cases and adjust the other existing governors
to that change (Aboorva Devarajan, Christian Loehle)
- Update kerneldoc comments for wake IRQ management functions that
have not been matching the code (Wang Jiayue)"

Pull KVM updates from Paolo Bonzini:
"Loongarch:
- Add more CPUCFG mask bits
- Improve feature detection
- Add lazy load support for FPU and binary translation (LBT) register
state
- Fix return value for memory reads from and writes to in-kernel
devices
- Add support for detecting preemption from within a guest
- Add KVM steal time test case to tools/selftests
ARM:
- Add support for FEAT_IDST, allowing ID registers that are not
implemented to be reported as a normal trap rather than as an UNDEF
exception
- Add sanitisation of the VTCR_EL2 register, fixing a number of
UXN/PXN/XN bugs in the process
- Full handling of RESx bits, instead of only RES0, and resulting in
SCTLR_EL2 being added to the list of sanitised registers
- More pKVM fixes for features that are not supposed to be exposed to
guests
- Make sure that MTE being disabled on the pKVM host doesn't give it
the ability to attack the hypervisor
- Allow pKVM's host stage-2 mappings to use the Force Write Back
version of the memory attributes by using the "pass-through'
encoding
- Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the
guest
- Preliminary work for guest GICv5 support
- A bunch of debugfs fixes, removing pointless custom iterators
stored in guest data structures
- A small set of FPSIMD cleanups
- Selftest fixes addressing the incorrect alignment of page
allocation
- Other assorted low-impact fixes and spelling fixes
RISC-V:
- Fixes for issues discoverd by KVM API fuzzing in
kvm_riscv_aia_imsic_has_attr(), kvm_riscv_aia_imsic_rw_attr(), and
kvm_riscv_vcpu_aia_imsic_update()
- Allow Zalasr, Zilsd and Zclsd extensions for Guest/VM
- Transparent huge page support for hypervisor page tables
- Adjust the number of available guest irq files based on MMIO
register sizes found in the device tree or the ACPI tables
- Add RISC-V specific paging modes to KVM selftests
- Detect paging mode at runtime for selftests
s390:
- Performance improvement for vSIE (aka nested virtualization)
- Completely new memory management. s390 was a special snowflake that
enlisted help from the architecture's page table management to
build hypervisor page tables, in particular enabling sharing the
last level of page tables. This however was a lot of code (~3K
lines) in order to support KVM, and also blocked several features.
The biggest advantages is that the page size of userspace is
completely independent of the page size used by the guest:
userspace can mix normal pages, THPs and hugetlbfs as it sees fit,
and in fact transparent hugepages were not possible before. It's
also now possible to have nested guests and guests with huge pages
running on the same host
- Maintainership change for s390 vfio-pci
- Small quality of life improvement for protected guests
x86:
- Add support for giving the guest full ownership of PMU hardware
(contexted switched around the fastpath run loop) and allowing
direct access to data MSRs and PMCs (restricted by the vPMU model).
KVM still intercepts access to control registers, e.g. to enforce
event filtering and to prevent the guest from profiling sensitive
host state. This is more accurate, since it has no risk of
contention and thus dropped events, and also has significantly less
overhead.

Merge tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"Core & protocols:
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.
This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.
Driver API:
- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.
- Add helper to create, prepare and enable managed clocks.
Device drivers:
- Add Huawei hinic3 PF etherner driver.
- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
controller.
- Add ethernet driver for MaxLinear MxL862xx switches
- Remove parallel-port Ethernet driver.
- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().

Merge tag 'kvm-x86-pmu-6.20' of https://github.com/kvm-x86/linux into HEAD
KVM mediated PMU support for 6.20 Add support for mediated PMUs, where KVM gives the guest full ownership of PMU hardware (contexted switched around the fastpath run loop) and allows direct access to data MSRs and PMCs (restricted by the vPMU model), but intercepts access to control registers, e.g. to enforce event filtering and to prevent the guest from profiling sensitive host state. To keep overall complexity reasonable, mediated PMU usage is all or nothing for a given instance of KVM (controlled via module param). The Mediated PMU is disabled default, partly to maintain backwards compatilibity for existing setup, partly because there are tradeoffs when running with a mediated PMU that may be non-starters for some use cases, e.g. the host loses the ability to profile guests with mediated PMUs, the fastpath run loop is also a blind spot, entry/exit transitions are more expensive, etc. Versus the emulated PMU, where KVM is "just another perf user", the mediated PMU delivers more accurate profiling and monitoring (no risk of contention and thus dropped events), with significantly less overhead (fewer exits and faster emulation/programming of event selectors) E.g. when running Specint-2017 on a single-socket Sapphire Rapids with 56 cores and no-SMT, and using perf from within the guest: Perf command: a. basic-sampling: perf record -F 1000 -e 6-instructions -a --overwrite b. multiplex-sampling: perf record -F 1000 -e 10-instructions -a --overwrite Guest performance overhead: --------------------------------------------------------------------------- | Test case | emulated vPMU | all passthrough | passthrough with | | | | | event filters | --------------------------------------------------------------------------- | basic-sampling | 33.62% | 4.24% | 6.21% | --------------------------------------------------------------------------- | multiplex-sampling | 79.32% | 7.34% | 10.45% | --------------------------------------------------------------------------- |

Merge tag 'sched-core-2026-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar:
"Scheduler Kconfig space updates:
- Further consolidate configurable preemption modes (Peter Zijlstra)
Reduce the number of architectures that are allowed to offer
PREEMPT_NONE and PREEMPT_VOLUNTARY, reducing the number of
preemption models from four to just two: 'full' and 'lazy' on
up-to-date architectures (arm64, loongarch, powerpc, riscv, s390,
x86).
None and voluntary are only available as legacy features on
platforms that don't implement lazy preemption yet, or which don't
even support preemption.
The goal is to eventually remove cond_resched() and voluntary
preemption altogether.
RSEQ based 'scheduler time slice extension' support (Thomas Gleixner
and Peter Zijlstra):
This allows a thread to request a time slice extension when it enters
a critical section to avoid contention on a resource when the thread
is scheduled out inside of the critical section.
- Add fields and constants for time slice extension
- Provide static branch for time slice extensions
- Add statistics for time slice extensions
- Add prctl() to enable time slice extensions
- Implement sys_rseq_slice_yield()
- Implement syscall entry work for time slice extensions
- Implement time slice extension enforcement timer
- Reset slice extension when scheduled
- Implement rseq_grant_slice_extension()
- entry: Hook up rseq time slice extension
- selftests: Implement time slice extension test
- Allow registering RSEQ with slice extension
- Move slice_ext_nsec to debugfs
- Lower default slice extension
- selftests/rseq: Add rseq slice histogram script
Scheduler performance/scalability improvements:
- Update rq->avg_idle when a task is moved to an idle CPU, which
improves the scalability of various workloads (Shubhang Kaushik)
- Reorder fields in 'struct rq' for better caching (Blake Jones)
- Fair scheduler SMP NOHZ balancing code speedups (Shrikanth Hegde):
- Move checking for nohz cpus after time check
- Change likelyhood of nohz.nr_cpus
- Remove nohz.nr_cpus and use weight of cpumask instead
- Avoid false sharing for sched_clock_irqtime (Wangyang Guo)
- Cleanups (Yury Norov):
- Drop useless cpumask_empty() in find_energy_efficient_cpu()
- Simplify task_numa_find_cpu()
- Use cpumask_weight_and() in sched_balance_find_dst_group()
DL scheduler updates:
- Add a deadline server for sched_ext tasks (by Andrea Righi and Joel
Fernandes, with fixes by Peter Zijlstra)
RT scheduler updates:
- Skip currently executing CPU in rto_next_cpu() (Chen Jinghuang)
Entry code updates and performance improvements (Jinjie Ruan)
This is part of the scheduler tree in this cycle due to inter-
dependencies with the RSEQ based time slice extension work:
- Remove unused syscall argument from syscall_trace_enter()
- Rework syscall_exit_to_user_mode_work() for architecture reuse
- Add arch_ptrace_report_syscall_entry/exit()
- Inline syscall_exit_work() and syscall_trace_enter()
Scheduler core updates (Peter Zijlstra):
- Rework sched_class::wakeup_preempt() and rq_modified_*()
- Avoid rq->lock bouncing in sched_balance_newidle()
- Rename rcu_dereference_check_sched_domain() =>
rcu_dereference_sched_domain()
- <linux/compiler_types.h>: Add the __signed_scalar_typeof() helper
Fair scheduler updates/refactoring (Peter Zijlstra and Ingo Molnar):
- Fold the sched_avg update
- Change rcu_dereference_check_sched_domain() to rcu-sched
- Switch to rcu_dereference_all()
- Remove superfluous rcu_read_lock()
- Limit hrtick work
- Join two #ifdef CONFIG_FAIR_GROUP_SCHED blocks
- Clean up comments in 'struct cfs_rq'
- Separate se->vlag from se->vprot
- Rename cfs_rq::avg_load to cfs_rq::sum_weight
- Rename cfs_rq::avg_vruntime to ::sum_w_vruntime & helper functions
- Introduce and use the vruntime_cmp() and vruntime_op() wrappers for
wrapped-signed aritmetics
- Sort out 'blocked_load*' namespace noise
Scheduler debugging code updates:
- Export hidden tracepoints to modules (Gabriele Monaco)
- Convert copy_from_user() + kstrtouint() to kstrtouint_from_user()
(Fushuai Wang)
- Add assertions to QUEUE_CLASS (Peter Zijlstra)
- hrtimer: Fix tracing oddity (Thomas Gleixner)
Misc fixes and cleanups:
- Re-evaluate scheduling when migrating queued tasks out of throttled
cgroups (Zicheng Qu)
- Remove task_struct->faults_disabled_mapping (Christoph Hellwig)
- Fix math notation errors in avg_vruntime comment (Zhan Xusheng)

Pull power management updates from Rafael Wysocki:
"By the number of commits, cpufreq is the leading party (again) and the
most visible change there is the removal of the omap-cpufreq driver
that has not been used for a long time (good riddance). There are also
quite a few changes in the cppc_cpufreq driver, mostly related to
fixing its frequency invariance engine in the case when the CPPC
registers used by it are not in PCC. In addition to that, support for
AM62L3 is added to the ti-cpufreq driver and the cpufreq-dt-platdev
list is updated for some platforms. The remaining cpufreq changes are
assorted fixes and cleanups.
Next up is cpuidle and the changes there are dominated by intel_idle
driver updates, mostly related to the new command line facility
allowing users to adjust the list of C-states used by the driver.
There are also a few updates of cpuidle governors, including two menu
governor fixes and some refinements of the teo governor, and a
MAINTAINERS update adding Christian Loehle as a cpuidle reviewer.
[Thanks for stepping up Christian!]
The most significant update related to system suspend and hibernation
is the one to stop freezing the PM runtime workqueue during system PM
transitions which allows some deadlocks to be avoided. There is also a
fix for possible concurrent bit field updates in the core device
suspend code and a few other minor fixes.
Apart from the above, several drivers are updated to discard the
return value of pm_runtime_put() which is going to be converted to a
void function as soon as everybody stops using its return value, PL4
support for Ice Lake is added to the Intel RAPL power capping driver,
and there are assorted cleanups, documentation fixes, and some
cpupower utility improvements.
Specifics:
- Remove the unused omap-cpufreq driver (Andreas Kemnade)
- Optimize error handling code in cpufreq_boost_trigger_state() and
make cpufreq_boost_trigger_state() return -EOPNOTSUPP if no policy
supports boost (Lifeng Zheng)
- Update cpufreq-dt-platdev list for tegra, qcom, TI (Aaron Kling,
Dhruva Gole, and Konrad Dybcio)
- Minor improvements to the cpufreq and cpumask rust implementation
(Alexandre Courbot, Alice Ryhl, Tamir Duberstein, and Yilin Chen)
- Add support for AM62L3 SoC to the ti-cpufreq driver (Dhruva Gole)
- Update arch_freq_scale in the CPPC cpufreq driver's frequency
invariance engine (FIE) in scheduler ticks if the related CPPC
registers are not in PCC (Jie Zhan)
- Assorted minor cleanups and improvements in ARM cpufreq drivers
(Juan Martinez, Felix Gu, Luca Weiss, and Sergey Shtylyov)
- Add generic helpers for sysfs show/store to cppc_cpufreq (Sumit
Gupta)
- Make the scaling_setspeed cpufreq sysfs attribute return the actual
requested frequency to avoid confusion (Pengjie Zhang)
- Simplify the idle CPU time granularity test in the ondemand cpufreq
governor (Frederic Weisbecker)
- Enable asym capacity in intel_pstate only when CPU SMT is not
possible (Yaxiong Tian)
- Update the description of rate_limit_us default value in cpufreq
documentation (Yaxiong Tian)
- Add a command line option to adjust the C-states table in the
intel_idle driver, remove the 'preferred_cstates' module parameter
from it, add C-states validation to it and clean it up (Artem
Bityutskiy)
- Make the menu cpuidle governor always check the time till the
closest timer event when the scheduler tick has been stopped to
prevent it from mistakenly selecting the deepest available idle
state (Rafael Wysocki)
- Update the teo cpuidle governor to avoid making suboptimal
decisions in certain corner cases and generally improve idle state
selection accuracy (Rafael Wysocki)
- Remove an unlikely() annotation on the early-return condition in
menu_select() that leads to branch misprediction 100% of the time
on systems with only 1 idle state enabled, like ARM64 servers
(Breno Leitao)
- Add Christian Loehle to MAINTAINERS as a cpuidle reviewer
(Christian Loehle)
- Stop flagging the PM runtime workqueue as freezable to avoid system
suspend and resume deadlocks in subsystems that assume asynchronous
runtime PM to work during system-wide PM transitions (Rafael
Wysocki)
- Drop redundant NULL pointer checks before acomp_request_free() from
the hibernation code handling image saving (Rafael Wysocki)
- Update wakeup_sources_walk_start() to handle empty lists of wakeup
sources as appropriate (Samuel Wu)
- Make dev_pm_clear_wake_irq() check the power.wakeirq value under
power.lock to avoid race conditions (Gui-Dong Han)
- Avoid bit field races related to power.work_in_progress in the core
device suspend code (Xuewen Yan)
- Make several drivers discard pm_runtime_put() return value in
preparation for converting that function to a void one (Rafael
Wysocki)
- Add PL4 support for Ice Lake to the Intel RAPL power capping driver
(Daniel Tang)
- Replace sprintf() with sysfs_emit() in power capping sysfs show
functions (Sumeet Pawnikar)
- Make dev_pm_opp_get_level() return value match the documentation
after a previous update of the latter (Aleks Todorov)
- Use scoped for each OF child loop in the OPP code (Krzysztof
Kozlowski)
- Fix a bug in an example code snippet and correct typos in the
energy model management documentation (Patrick Little)
- Fix miscellaneous problems in cpupower (Kaushlendra Kumar):
* idle_monitor: Fix incorrect value logged after stop
* Fix inverted APERF capability check
* Use strcspn() to strip trailing newline

Pull vfs initrd removal from Christian Brauner: "Remove the deprecated linuxrc-based initrd code path and related dead code. The linuxrc initrd path was deprecated in 2020 and this series completes its removal. If we see real-life regressions we'll revert. The core change removes handle_initrd() and init_linuxrc() — the entire flow that ran /linuxrc from an initrd, pivoted roots, and handed off to the real root filesystem. With that gone, initrd_load() becomes void (no longer short-circuits prepare_namespace()), rd_load_image() is simplified to always load /initrd.image instead of taking a path, and rd_load_disk() is deleted. The /proc/sys/kernel/real-root-dev sysctl and its backing variable are removed since they only existed for linuxrc to communicate the real root device back to the kernel. The no-op load_ramdisk= and prompt_ramdisk= parameters are dropped, and noinitrd and ramdisk_start= gain deprecation warnings. Initramfs is entirely unaffected. The non-linuxrc initrd path (root=/dev/ram0) is preserved but now carries a deprecation warning targeting January 2027 removal" * tag 'vfs-7.0-rc1.initrd' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: init: remove /proc/sys/kernel/real-root-dev initrd: remove deprecated code path (linuxrc) init: remove deprecated "load_ramdisk" and "prompt_ramdisk" command line parameters |

set of API, rcu_read_{,un}lock_tasks_trace(), becomes possible as
well. Compared to the previous rcu_read_{,un}lock_trace(), the new
API avoid the task_struct accesses thanks to the SRCU-fast semantics.
As a result, the old rcu_read{,un}lock_trace() API is now deprecated.
- RCU Torture Test:
- Multiple improvements on kvm-series.sh (parallel run and
progress showing metrics)
- Add context checks to rcu_torture_timer()
- Make config2csv.sh properly handle comments in .boot files
- Include commit discription in testid.txt
- Miscellaneous RCU changes:
- Reduce synchronize_rcu() latency by reporting GP kthread's
CPU QS early
- Use suitable gfp_flags for the init_srcu_struct_nodes()
- Fix rcu_read_unlock() deadloop due to softirq
- Correctly compute probability to invoke ->exp_current()
in rcutorture
- Make expedited RCU CPU stall warnings detect stall-end races
- RCU nocb:
- Remove unnecessary WakeOvfIsDeferred wake path and callback
overload handling
- Extract nocb_defer_wakeup_cancel() helper

workqueue: add time-based panic for stalls
Add a new module parameter 'panic_on_stall_time' that triggers a panic when a workqueue stall persists for longer than the specified duration in seconds. Unlike 'panic_on_stall' which counts accumulated stall events, this parameter triggers based on the duration of a single continuous stall. This is useful for catching truly stuck workqueues rather than accumulating transient stalls. Usage: workqueue.panic_on_stall_time=120 This would panic if any workqueue pool has been stalled for 120 seconds or more. The stall duration is measured from the workqueue last progress (poll_ts) which accounts for legitimate system stalls.

bootconfig: Terminate value search if it hits a newline
Terminate the value search for a key if it hits a newline and make
the value empty.
When we pass a bootconfig with an empty value terminated by the
newline, like below::
foo =
bar = value
Current bootconfig interprets it as a single entry::
foo = "bar = value";
The Documentation/admin-guide/bootconfig.rst defines the value
itself is terminated by newline:
The value has to be terminated by semi-colon (``;``) or newline (``\n``).
but it does not define when the value search is terminated.
This changes the behavior to be more line-oriented, so that it is
clearer in how it works.
- The value search of key-value pair will be terminated by a comment
or newline.
- The value search of an array will continue beyond comments and
newlines.
Thus, with this update, the above example is interpreted as::
foo = "";
bar = "value";
And the below example will cause a syntax error because "bar" is expected
as a key but it has ','.
foo =
bar, buz
According to this change, one wrong example config is updated.

workqueue: add CONFIG_BOOTPARAM_WQ_STALL_PANIC option
Add a kernel config option to set the default value of workqueue.panic_on_stall, similar to CONFIG_BOOTPARAM_SOFTLOCKUP_PANIC, CONFIG_BOOTPARAM_HARDLOCKUP_PANIC and CONFIG_BOOTPARAM_HUNG_TASK_PANIC. This allows setting the number of workqueue stalls before triggering a kernel panic at build time, which is useful for high-availability systems that need consistent panic-on-stall, in other words, those servers which run with CONFIG_BOOTPARAM_*_PANIC=y already. The default remains 0 (disabled). Setting it to 1 will panic on the first stall, and higher values will panic after that many stall warnings. The value can still be overridden at runtime via the workqueue.panic_on_stall boot parameter or sysfs. Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Tejun Heo <tj@kernel.org> |

panic: add panic_force_cpu= parameter to redirect panic to a specific CPU
Some platforms require panic handling to execute on a specific CPU for crash dump to work reliably. This can be due to firmware limitations, interrupt routing constraints, or platform-specific requirements where only a single CPU is able to safely enter the crash kernel. Add the panic_force_cpu= kernel command-line parameter to redirect panic execution to a designated CPU. When the parameter is provided, the CPU that initially triggers panic forwards the panic context to the target CPU via IPI, which then proceeds with the normal panic and kexec flow. The IPI delivery is implemented as a weak function (panic_smp_redirect_cpu) so architectures with NMI support can override it for more reliable delivery. If the specified CPU is invalid, offline, or a panic is already in progress on another CPU, the redirection is skipped and panic continues on the current CPU.

modsign: Enable ML-DSA module signing
Allow ML-DSA module signing to be enabled. Note that OpenSSL's CMS_*() function suite does not, as of OpenSSL-3.6, support the use of CMS_NOATTR with ML-DSA, so the prohibition against using signedAttrs with module signing has to be removed. The selected digest then applies only to the algorithm used to calculate the digest stored in the messageDigest attribute. The OpenSSL development branch has patches applied that fix this[1], but it appears that that will only be available in OpenSSL-4. [1] https://github.com/openssl/openssl/pull/28923 sign-file won't set CMS_NOATTR if openssl is earlier than v4, resulting in the use of signed attributes. The ML-DSA algorithm takes the raw data to be signed without regard to what digest algorithm is specified in the CMS message. The CMS specified digest algorithm is ignored unless signedAttrs are used; in such a case, only SHA512 is permitted.
