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!

+/*
+ * linux/drivers/message/fusion/mptbase.c
+ * High performance SCSI + LAN / Fibre Channel device drivers.
+ * This is the Fusion MPT base driver which supports multiple
+ * (SCSI + LAN) specialized protocol drivers.
+ * For use with PCI chip/adapter(s):
+ * LSIFC9xx/LSI409xx Fibre Channel
+ * running LSI Logic Fusion MPT (Message Passing Technology) firmware.
+ *
+ * Credits:
+ * There are lots of people not mentioned below that deserve credit
+ * and thanks but won't get it here - sorry in advance that you
+ * got overlooked.
+ *
+ * This driver would not exist if not for Alan Cox's development
+ * of the linux i2o driver.
+ *
+ * A special thanks to Noah Romer (LSI Logic) for tons of work
+ * and tough debugging on the LAN driver, especially early on;-)
+ * And to Roger Hickerson (LSI Logic) for tirelessly supporting
+ * this driver project.
+ *
+ * A special thanks to Pamela Delaney (LSI Logic) for tons of work
+ * and countless enhancements while adding support for the 1030
+ * chip family. Pam has been instrumental in the development of
+ * of the 2.xx.xx series fusion drivers, and her contributions are
+ * far too numerous to hope to list in one place.
+ *
+ * All manner of help from Stephen Shirron (LSI Logic):
+ * low-level FC analysis, debug + various fixes in FCxx firmware,
+ * initial port to alpha platform, various driver code optimizations,
+ * being a faithful sounding board on all sorts of issues & ideas,
+ * etc.
+ *
+ * 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!
+ *
+ * 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 really huge debt of gratitude is owed to Eddie C. Dost
+ * for gobs of hard work fixing and optimizing LAN code.
+ * THANK YOU!
