  SVN rev 210893 on 2010-08-05 20:02:59Z by gnn
  
  MFC: 210621
  
  Make sure that we clear the correct bits when we turn off
  a PMC.  It was possible that we could have turned a bit on but
  never cleared it.
  
  Extend the calls to rdmsr() to all necessary functions, not
  just those which previously caused a panic.
