    kernel - Improve per-cpu caching of pv_entry's
    
    * The vm_zone (zalloc) code needs to be replaced with objcache, but until
      we do continue improving certain critical paths in it.
    
    * Burst fill an empty per-cpu cache to reduce overheads when working with
      large numbers of processes with large shared address spaces (postgres,
      mysql, etc).  This reduces contention under heavy use situations.
