    kernel - zero pages during idle
    
    Bring in base work by Venkatesh Srinivas:
    
    * vm/vm_zeropage.c and bzeront() code.
    
    Plus make the following adjustments:
    
    * Move the bzeront code from platform/ to cpu/ and add a x86_64 version
      of bzeront().
    
    * Expose the page zeroing rate via sysctl and adjust the default upwards.
    
    * Expose the movnti feature via sysctl (defaults to off).
    
    * Change poll interval from 1 second to 1/10 second.
    
    * Correct a bug where the MP lock was not being initially released.  The
      thread is created with the MP lock held.  This was causing the hysteresis
      check to fail.
    
    * Correct a bug where vm_page_zero_count was being double-incremented
      due to changes in how the zerod page is freed.
    
    * Clean up the code syntax a bit.
