Objtool reports the following:
arch/x86/kvm/vmx/vmenter.o: warning: objtool: vmx_vmenter()+0x14: call without frame pointer save/setup
But frame pointers are necessarily broken anyway, because
__vmx_vcpu_run() clobbers RBP with the guest's value before calling
vmx_vmenter(). So calling without a frame pointer doesn't make things
any worse.
Make objtool happy by changing the call to a UD2.
