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!

+
+    A PCMCIA ethernet driver for SMC91c92-based cards.
+
+    This driver supports Megahertz PCMCIA ethernet cards; and
+    Megahertz, Motorola, Ositech, and Psion Dacom ethernet/modem
+    multifunction cards.
+
+    Copyright (C) 1999 David A. Hinds -- dahinds@users.sourceforge.net
+
+    smc91c92_cs.c 1.122 2002/10/25 06:26:39
+
+    This driver contains code written by Donald Becker
+    (becker@scyld.com), Rowan Hughes (x-csrdh@jcu.edu.au),
+    David Hinds (dahinds@users.sourceforge.net), and Erik Stahlman
+    (erik@vt.edu).  Donald wrote the SMC 91c92 code using parts of
+    Erik's SMC 91c94 driver.  Rowan wrote a similar driver, and I've
+    incorporated some parts of his driver here.  I (Dave) wrote most
+    of the PCMCIA glue code, and the Ositech support code.  Kelly
+    Stephens (kstephen@holli.com) added support for the Motorola
+    Mariner, with help from Allen Brost.
