Filled in the stubs for the windows functions: KeQueryActiveProcessorCount(0) and KeGetCurrentProcessorNumberEx(NULL). KeQueryActiveProcessorCount(0) maps one to one to num_online_cpus() KeGetCurrentProcessorNumberEx(NULL) maps to raw_smp_processor_id(), however this can also be smp_processor_id(), we have to decide based on preemption, the latter checks for preemption and throws a warning if it is executed in preemptible code. (I dont know the kernel code well enough so this may need some discussion)
