  Modified files:        (Branch: RELENG_5)
    sys/sparc64/sparc64  pmap.c 
  Log:
  MFC revision 1.140
   Eliminate an unnecessary call to vm_page_busy().
  
  MFC revision 1.141
   Pass VM_ALLOC_NOBUSY to vm_page_grab() so that we don't have to call
   vm_page_flag_clear(PG_BUSY).  The object lock is held the entire time.
   Thus, whether or not the PG_BUSY flag is set is invisible to others.
  
  MFC revision 1.145
   Acquire the source pmap's lock in pmap_copy().
