- Remove the following sysctl:   kern.sched.ipiwakeup.onecpu   kern.sched.ipiwakeup.htt2
- Remove the following sysctl:
  kern.sched.ipiwakeup.onecpu
  kern.sched.ipiwakeup.htt2

  Because they are absolutely obsolete. Probabilly the whole wakeup
  forward mechanism should be revisited for a better fitting in modern
  hw.
- As map2 variable is no longer used rename map3 to map2
- Fix a string by making more informative the msg and removing the
  arguments passing
