   I am working on 2200S RAID controller and using aac driver from RELEGN4 ,
aac_disk.c in the driver uses pmap_enter for coping the virtual pages to
some physical location. In FreeBSD 4.10 pmap_kenter_temporary is used which
return the address which is passed to the controller for dumping on kernel
panic where as this is not happening with pmap_enter , can any one tell me
the difference between pmap_enter and pmap_kenter_temporary  (both  this
file are present in i386/pmap.c.

Any suggestions will be of great help.
