Subject: [PATCH 0/7] Lazy preemption bits

This series adds RCU and some leftover scheduler bits for lazy
preemption. Goes on top of PeterZ's series:

 https://lore.kernel.org/20241007074609.447006177@infradead.org

Tracing and RISCV bits from Sebastian at:
 https://lore.kernel.org/lkml/20241009105709.887510-1-bigeasy@linutronix.de/

Please review.

Ankur Arora (6):
  sched: warn for high latency with TIF_NEED_RESCHED_LAZY
  rcu: limit PREEMPT_RCU configurations
  rcu: fix header guard for rcu_all_qs()
  rcu: handle quiescent states for PREEMPT_RCU=n, PREEMPT_COUNT=y
  rcu: rename PREEMPT_AUTO to PREEMPT_LAZY
  osnoise: handle quiescent states for PREEMPT_RCU=n, PREEMPTION=y

Shrikanth Hegde (1):
  powerpc: add support for PREEMPT_LAZY
