  Log:
  Don't use the tpa instruction to implement pmap_kextract. The tpa
  instruction requires that a translation is present in the TC. This
  may trigger a TLB miss and a subsequent call to vm_fault().
  This implementation is deliberately non-inline for debugging and
  profiling purposes. Partial or full inlining should eventually be
  done.
