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!

+README for WarpEngine/A4000T/A4091 SCSI kernels.
+
+Use the following options to disable options in the SCSI driver.
+
+Using amiboot for example.....
+
+To disable Synchronous Negotiation....
+
+        amiboot -k kernel 53c7xx=nosync:0       
+
+To disable Disconnection....
+        
+        amiboot -k kernel 53c7xx=nodisconnect:0
+
+To disable certain SCSI devices...
+
+        amiboot -k kernel 53c7xx=validids:0x3F
+
+        this allows only device ID's 0,1,2,3,4 and 5 for linux to handle.
+        (this is a bitmasked field - i.e. each bit represents a SCSI ID)
+
+These commands work on a per controller basis and use the option 'next' to
+move to the next controller in the system.
+
+e.g.
+        amiboot -k kernel 53c7xx=nodisconnect:0,next,nosync:0
+
+        this uses No Disconnection on the first controller and Asynchronous
+        SCSI on the second controller.
+
+Known Issues:
+
+Two devices are known not to function with the default settings of using
+synchronous SCSI. These are the Archive Viper 150 Tape Drive and the 
+SyQuest SQ555 removeable hard drive. When using these devices on a controller
+use the 'nosync:0' option.
+
+Please try these options and post any problems/successes to me.
