  Modified files:
    sys/i386/i386        pmap.c 
  Log:
  Eliminate all TLB shootdowns by pmap_pte_quick(): By temporarily pinning
  the thread that calls pmap_pte_quick() and by virtue of the page queues
  lock being held, we can manage PADDR1/PMAP1 as a CPU private mapping.
  
  The most common effect of this change is to reduce the overhead of the page
  daemon on multiprocessors.
