  Log:
  SVN rev 192628 on 2009-05-23 07:58:56Z by alc
  
  Preset the modified bit in the PTE when pmap_enter() is called during a
  write fault or while wiring a mapping that must support write access.
  
  In general, this change should reduce the number of traps that occur for
  the purpose of setting the modified bit.  More specifically, this change
  should prevent traps while holding locks in a sysctl handler.  See
  kern/kern_sysctl.c revisions 1.168 and 1.195 (svn r192160) for further
  details.
