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!

+ *  linux/drivers/message/fusion/mptlan.c
+ *      IP Over Fibre Channel device driver.
+ *      For use with PCI chip/adapter(s):
+ *          LSIFC9xx/LSI409xx Fibre Channel
+ *      running LSI Logic Fusion MPT (Message Passing Technology) firmware.
+ *
+ *  Credits:
+ *      This driver would not exist if not for Alan Cox's development
+ *      of the linux i2o driver.
+ *
+ *      Special thanks goes to the I2O LAN driver people at the
+ *      University of Helsinki, who, unbeknownst to them, provided
+ *      the inspiration and initial structure for this driver.
+ *
+ *      A huge debt of gratitude is owed to David S. Miller (DaveM)
+ *      for fixing much of the stupid and broken stuff in the early
+ *      driver while porting to sparc64 platform.  THANK YOU!
+ *
+ *      A really huge debt of gratitude is owed to Eddie C. Dost
+ *      for gobs of hard work fixing and optimizing LAN code.
+ *      THANK YOU!
