Linux-2.6.12-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!

+ * Fixes/additions:
+ * Steve Ralston:
+ * Multiple device handling error fixes,
+ * Added a queue depth.
+ * Alan Cox:
+ * FC920 has an rmw bug. Dont or in the end marker.
+ * Removed queue walk, fixed for 64bitness.
+ * Rewrote much of the code over time
+ * Added indirect block lists
+ * Handle 64K limits on many controllers
+ * Don't use indirects on the Promise (breaks)
+ * Heavily chop down the queue depths
+ * Deepak Saxena:
+ * Independent queues per IOP
+ * Support for dynamic device creation/deletion
+ * Code cleanup
+ * Support for larger I/Os through merge* functions
+ * (taken from DAC960 driver)
+ * Boji T Kannanthanam:
+ * Set the I2O Block devices to be detected in increasing
+ * order of TIDs during boot.
+ * Search and set the I2O block device that we boot off
+ * from as the first device to be claimed (as /dev/i2o/hda)
+ * Properly attach/detach I2O gendisk structure from the
+ * system gendisk list. The I2O block devices now appear in
+ * /proc/partitions.
+ * Markus Lidel <Markus.Lidel@shadowconnect.com>:
+ * Minor bugfixes for 2.6.
