Pull scheduler fixes from Ingo Molnar: - Fix spurious failures in rseq self-tests (Mark Brown) - Fix rseq rseq::cpu_id_start ABI regression due to TCMalloc's creative use of the supposedly read-only field The fix is to introduce a new ABI variant based on a new (larger) rseq area registration size, to keep the TCMalloc use of rseq backwards compatible on new kernels (Thomas Gleixner) - Fix wakeup_preempt_fair() for not waking up task (Vincent Guittot) - Fix s64 mult overflow in vruntime_eligible() (Zhan Xusheng) * tag 'sched-urgent-2026-05-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/fair: Fix wakeup_preempt_fair() for not waking up task sched/fair: Fix overflow in vruntime_eligible() selftests/rseq: Expand for optimized RSEQ ABI v2 rseq: Reenable performance optimizations conditionally rseq: Implement read only ABI enforcement for optimized RSEQ V2 mode selftests/rseq: Validate legacy behavior selftests/rseq: Make registration flexible for legacy and optimized mode selftests/rseq: Skip tests if time slice extensions are not available rseq: Revert to historical performance killing behaviour rseq: Don't advertise time slice extensions if disabled rseq: Protect rseq_reset() against interrupts rseq: Set rseq::cpu_id_start to 0 on unregistration selftests/rseq: Don't run tests with runner scripts outside of the scripts
