  Modified files:
    sys/alpha/include    pmap.h 
    sys/alpha/alpha      pmap.c trap.c 
  Log:
  Simplify the implementation of pmap_emulate_reference(). The new version
  simply manipulates the pte which faulted instead of traversing the mapping
  list for that page. This makes it possible to complete the trap without
  needing locks and incidentally improves the accuracy of some statistics
  used by the VM system.
