Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ * DESCRIPTION:
+ *
+ * This is the Linux low-level SCSI driver for Initio INI-9X00U/UW SCSI host
+ * adapters
+ *
+ * 08/06/97 hc	- v1.01h
+ *		- Support inic-940 and inic-935
+ * 09/26/97 hc	- v1.01i
+ *		- Make correction from J.W. Schultz suggestion
+ * 10/13/97 hc	- Support reset function
+ * 10/21/97 hc	- v1.01j
+ *		- Support 32 LUN (SCSI 3)
+ * 01/14/98 hc	- v1.01k
+ *		- Fix memory allocation problem
+ * 03/04/98 hc	- v1.01l
+ *		- Fix tape rewind which will hang the system problem
+ *		- Set can_queue to tul_num_scb
+ * 06/25/98 hc	- v1.01m
+ *		- Get it work for kernel version >= 2.1.75
+ *		- Dynamic assign SCSI bus reset holding time in init_tulip()
+ * 07/02/98 hc	- v1.01n
+ *		- Support 0002134A
+ * 08/07/98 hc  - v1.01o
+ *		- Change the tul_abort_srb routine to use scsi_done. <01>
+ * 09/07/98 hl  - v1.02
+ *              - 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
