  Log:
  Re-enable the idle page-zeroing code.  Remove all IPIs from the idle
  page-zeroing code as well as from the general page-zeroing code and use a
  lazy tlb page invalidation scheme based on a callback made at the end
  of mi_switch.
  
  A number of people came up with this idea at the same time so credit
  belongs to Peter, John, and Jake as well.
