Subject: kvm: fix !SMP build error
From: Ingo Molnar <[email protected]>
fix !SMP build error:
drivers/kvm/kvm_main.c: In function 'kvm_flush_remote_tlbs':
drivers/kvm/kvm_main.c:220: error: implicit declaration of function 'smp_call_function_mask'
(and also avoid unused function warning related to up_smp_call_function()
not making use of the 'func' parameter.)
