    kernel - vm_object work
    
    * Adjust OBJT_SWAP object management to be more SMP friendly.  The hash
      table now uses a combined structure to reduce unnecessary cache
      interactions.
    
    * Allocate VM objects via kmalloc() instead of zalloc.  Remove the zalloc
      pool for VM objects and use kmalloc().  Early initialization of the kernel
      does not have to access vm_object allocation functions until after basic
      VM initialization.
    
    * Remove a vm_page_cache console warning that is no longer applicable.
      (It could be triggered by the RSS rlimit handling code).
