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!

+        aten.c is a low-level protocol driver for the ATEN EH-100
+        parallel port adapter.  The EH-100 supports 4-bit and 8-bit
+        modes only.  There is also an EH-132 which supports EPP mode
+        transfers.  The EH-132 is not yet supported.
