alc 9c821fd980 - Make pmap_emulate_reference() MP and preemption safe. Previously, it
contained "sanity" checks that could be violated if another CPU modified
   the pmap between the emulation trap and locking the pmap in
   pmap_emulate_reference().  As a result, the pte could be inconsistent
   with the access that caused the emulation trap.  In such cases,
   pmap_emulate_reference() now flushes the current CPU's TLB entry and
   returns.
 - Make pmap_changebit() an inline function, reducing object code size.
