Define smp_call_function_many for UP

Otherwise those using it in transition patches (eg. kvm) can't compile
with CONFIG_SMP=n:

arch/x86/kvm/../../../virt/kvm/kvm_main.c: In function 'make_all_cpus_request':
arch/x86/kvm/../../../virt/kvm/kvm_main.c:380: error: implicit declaration of function 'smp_call_function_many'
