It's not new enforcement, just syntatic sugar (though it's tasty sugar). All fields in struct kvm_mmu_role_regs are const specifically to prevent such a struct from being changed regardless of how a pointer was obtained.
struct kvm_mmu_role_regs { const unsigned long cr0; const unsigned long cr4; const u64 efer; };
