  Log:
  SVN rev 211217 on 2010-08-12 10:09:28Z by jchandra
  
  Implement pmap changes suggested by alc@:
  
  1. Move dirty bit emulation code that is duplicted for kernel and user
  in trap.c to a function pmap_emulate_modified() in pmap.c.
  
  2. While doing dirty bit emulation, it is not necessary to update the
  TLB entry on all CPUs using smp_rendezvous(), we can just update the
  TLB entry on the current CPU, and let the other CPUs update their TLB
  entry lazily if they get an exception.
