Hi, 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. Thanks, Romil Shah
