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!

2* sym53c500_cs.c Bob Tracy (rct@frus.com)
3*
4* A rewrite of the pcmcia-cs add-on driver for newer (circa 1997)
5* New Media Bus Toaster PCMCIA SCSI cards using the Symbios Logic
6* 53c500 controller: intended for use with 2.6 and later kernels.
7* The pcmcia-cs add-on version of this driver is not supported
8* beyond 2.4. It consisted of three files with history/copyright
9* information as follows:
10*
11* SYM53C500.h
12* Bob Tracy (rct@frus.com)
13* Original by Tom Corner (tcorner@via.at).
14* Adapted from NCR53c406a.h which is Copyrighted (C) 1994
15* Normunds Saumanis (normunds@rx.tech.swh.lv)
16*
17* SYM53C500.c
18* Bob Tracy (rct@frus.com)
19* Original driver by Tom Corner (tcorner@via.at) was adapted
20* from NCR53c406a.c which is Copyrighted (C) 1994, 1995, 1996
21* Normunds Saumanis (normunds@fi.ibm.com)
22*
23* sym53c500.c
24* Bob Tracy (rct@frus.com)
25* Original by Tom Corner (tcorner@via.at) was adapted from a
26* driver for the Qlogic SCSI card written by
27* David Hinds (dhinds@allegro.stanford.edu).
