	  Virtual SMP uses the processor's VPEs  to implement virtual
	  processors. In currently available configuration of the 34K processor
	  this allows for a dual processor. Both processors will share the same
	  primary caches; each will obtain the half of the TLB for it's own
	  exclusive use. For a layman this model can be described as similar to
	  what Intel calls Hyperthreading.
