 *              - Change the INI9100U define and proc_dir_entry to
 *                reflect the newer Kernel 2.1.118, but the v1.o1o
 *                should work with Kernel 2.1.118.
 * 09/20/98 wh  - v1.02a
 *              - Support Abort command.
 *              - Handle reset routine.
 * 09/21/98 hl  - v1.03
 *              - remove comments.
 * 12/09/98 bv	- v1.03a
 *		- Removed unused code
 * 12/13/98 bv	- v1.03b
 *		- Remove cli() locking for kernels >= 2.1.95. This uses
 *		  spinlocks to serialize access to the pSRB_head and
 *		  pSRB_tail members of the HCS structure.
 * 09/01/99 bv	- v1.03d
 *		- Fixed a deadlock problem in SMP.
 * 21/01/99 bv	- v1.03e
 *		- Add support for the Domex 3192U PCI SCSI
 *		  This is a slightly modified patch by
 *		  Brian Macy <bmacy@sunshinecomputing.com>
 * 22/02/99 bv	- v1.03f
 *		- Didn't detect the INIC-950 in 2.0.x correctly.
 *		  Now fixed.
 * 05/07/99 bv	- v1.03g
 *		- Changed the assumption that HZ = 100
 * 10/17/03 mc	- v1.04
 *		- added new DMA API support
 * 06/01/04 jmd	- v1.04a
 *		- Re-add reset_bus support
