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!

+
+    A PCMCIA ethernet driver for NS8390-based cards
+
+    This driver supports the D-Link DE-650 and Linksys EthernetCard
+    cards, the newer D-Link and Linksys combo cards, Accton EN2212
+    cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
+    mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
+    Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
+    mode.  It will also handle the Socket EA card in either mode.

+    The network driver code is based on Donald Becker's NE2000 code:

+    CCAE support.  Drivers merged back together, and shared-memory
+    Socket EA support added, by Ken Raeburn, September 1995.
