2.6.23 git current compile error on UP
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' make[2]: *** [drivers/kvm/kvm_main.o] Error 1
make[1]: *** [drivers/kvm] Error 2

Looks like that function calls smp_call_function_mask() which is never defined for UP. Nobody else uses it that way, so I'm not sure what the right fix is. I'm not even sure kvm_flush_remote_tlbs() is safe with its raw_smp_processor_id() use. Is there a reason it can't get preempted?

Avi has already posted a patch to correct this.
