init/Kconfig: Require a release version of clang-22 for CC_HAS_COUNTED_BY_PTR
Commit 150a04d817d8 ("compiler_types.h: Attributes: Add __counted_by_ptr macro") used Clang 22.0.0 as a minimum supported version for __counted_by_ptr, which made sense while 22.0.0 was the version of LLVM's main branch to allow developers to easily test and develop uses of __counted_by_ptr in their code. However, __counted_by_ptr requires a change [1] merged towards the end of the 22 development cycle to avoid errors when applied to void pointers.
In file included from fs/xfs/xfs_attr_inactive.c:18: fs/xfs/libxfs/xfs_attr.h:59:2: error: 'counted_by' cannot be applied to a pointer with pointee of unknown size because 'void' is an incomplete type 59 | void *buffer __counted_by_ptr(bufsize); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is disruptive for deployed prerelease clang-22 builds (such as Android LLVM) or when bisecting between llvmorg-21-init and the fix.
Require a released version of clang-22 (i.e., 21.1.0 or newer) to enabled __counted_by_ptr to ensure all fixes needed for proper support are present.

init/Kconfig: Adjust fixed clang version for __builtin_counted_by_ref
Commit d39a1d7486d9 ("compiler_types: Disable __builtin_counted_by_ref for Clang") used 22.0.0 as the fixed version for a compiler crash but the fix was only merged in main (23.0.0) and release/22.x (22.1.0). With the current fixed version number, prerelease or Android LLVM 22 builds will still be able to hit the compiler crash when building the kernel. This can be particularly disruptive when bisecting LLVM.
Use 21.1.0 as the fixed version number to ensure the fix for this crash is always present.

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% | ---------------------------------------------------------------------------

kbuild: uapi: drop dependency on CC_CAN_LINK
The header tests try to compile each header. Some UAPI headers depend on libc headers so they need a full userspace toolchain to build. This dependency is expressed in kconfig as a dependency on CC_CAN_LINK. Many kernel builds do not satisfy CC_CAN_LINK as they only use a minimal kernel (cross-) compiler. In those configurations the UAPI headers are not tested at all.
However most UAPI headers do not even depend on any libc headers, and such dependencies are undesired in any case. Also the static analysis performed by headers_check.pl does not need CC_CAN_LINK.
Drop the hard dependency on CC_CAN_LINK and instead skip the affected compilation step for exactly those headers which require libc.

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)
- sched/cpufreq: Use %pe format for PTR_ERR() printing (zenghongling)"
