Ah, thanks! From a quick scan, the only thing I spot is that CONFIG_KVM_GUEST is also not an arm64 thing, and only exists on x86 & powerpc, so pulling that out too would be nice. That aside, this looks good to me; having the infrastructure to do this per-arch is nice!

Add CFcommon.arch for the various arch's need for rcutorture. According to [1] and [2], this patch Fixes: a6fda6dab93c ("rcutorture: Tweak kvm options") by moving x86 specific kernel option CONFIG_HYPERVISOR_GUEST to CFcommon.arch The patch has been revised and improved under Paul E. McKenney's guidance [3].
