Pull RCU selftest fixes from Boqun Feng:
 "Fix a regression in RCU torture test pre-defined scenarios caused by
  commit 7dadeaa6e851 ("sched: Further restrict the preemption modes")
  which limits PREEMPT_NONE to architectures that do not support
  preemption at all and PREEMPT_VOLUNTARY to those architectures that do
  not yet have PREEMPT_LAZY support.

  Since major architectures (e.g. x86 and arm64) no longer support
  CONFIG_PREEMPT_NONE and CONFIG_PREEMPT_VOLUNTARY, using them in
  rcutorture, rcuscale, refscale, and scftorture pre-defined scenarios
  causes config checking errors.

  Switch these kconfigs to PREEMPT_LAZY"
