KVM: fix !SMP build error (a5fbb6d1) · Commits · 戴 / test

fix a !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.)
