Subject: [RFC PATCH 1/4] KVM: selftests: Guard struct kvm_vcpu_events with __KVM_HAVE_VCPU_EVENTS

The struct kvm_vcpu_events code is only available on certain architectures
(arm, arm64 and x86). To be able to compile kvm_util.c also for other
architectures, we've got to fence the code with __KVM_HAVE_VCPU_EVENTS.

That would be nice, yes. But if you don't want to be responsible for
s390x-related KVM selftest patches, please let me know, then I'll drop
these hunks from the patches again.

I can take care of these (as part of the normal KVM maintainership).

According to the MAINTAINERS patches, you want me to pick these patches. Correct?
