Subject: Testing preemptibility test in xen_setup_cpu_clockevents()

With 250a1ac685f (x86, smpboot: Remove pointless preempt_disable() in 
native_smp_prepare_cpus()) HVM guests no longer boot since we are 
hitting BUG_ON(preemptible()) in xen_setup_cpu_clockevents().

I don't think we need this test (PV or HVM), do we?
