Linus Torvalds 9a0f53e0cf Merge tag 'csd-lock.2023.10.23a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu ...

Pull CSD lock update from Paul McKenney:
 "This adds a kernel boot parameter that causes the kernel to panic if
  one of the call_smp_function() APIs is stalled for more than the
  specified duration.

  This is useful in deployments in which a clean panic is preferable to
  an indefinite stall"
