ks_ was the best I could come up with too. But looking at it in code, I find it
more distracting than helpful. It's kind of like the uncanny valley effect, where
ks_ *just* close enough to kvm_ that it makes me think something is wrong.

struct kvm_sregs sregs;
struct kvm_regs regs;
struct ks_vcpu *vcpu;
struct kvm_run *run;
