How did this work? It used to attempt the tlb entry for a mapping it is
removing by using the va it is replacing it with, NO!.
Calculate the va of the mapping by inverting the pte_hi calculation
producing bits 4-19 of the address. This is enough to correctly invalidate
the tlb entry for the mapping being removed.
