Hi all,

After merging the rcu tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

ERROR: modpost: "srcu_check_nmi_safety" [arch/x86/kvm/kvm.ko] undefined!

Presumably caused by commit

  54a118fce487 ("srcu: Debug NMI safety even on archs that don't require it")

I have used the rcu tree from next-20221017 for today.
