Can you give all helpers this treatment (rename "role" => "cpu_mode")? I got
tripped up a few times reading patches because the ones where it wasn't necessary,
i.e. where there's only a single kvm_mmu_role paramenter, were left as-is.
I think kvm_calc_shadow_npt_root_page_role() and kvm_calc_shadow_mmu_root_page_role()
are the only offenders.
