i have triggered this and fixed it the right way - see the patch below. 
This fixes the 2.6.24-rc1 build error.

Subject: kvm: fix !SMP build error
From: Ingo Molnar <mingo@elte.hu>

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.)
