  o  When not making a translation cache-inhibit and guarded (PTE_I|PTE_G)
     make it memory-coherency enforced (PTE_M). This is required for SMP
     to work.
  o  Serialize tlbie operations and implement the tlbie operation in a
     function called tlbie(). Hardware can end up in a live-lock if
     between the tlbsync and subsequent sync on one processor another
     processor executes a tlbie or tlbsync.
  o  Eliminate the following defines:
          TLBIE, TLBSYNC, SYNC and EIEIO
     Use either inline assembly statements or inline functions defined
     in <machine/cpufunc.h>
