1656 marketesed into SMVP.
1657 Virtual SMP uses the processor's VPEs to implement virtual
1658 processors. In currently available configuration of the 34K processor
1659 this allows for a dual processor. Both processors will share the same
1660 primary caches; each will obtain the half of the TLB for it's own
1661 exclusive use. For a layman this model can be described as similar to
1662 what Intel calls Hyperthreading.
