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!

+/*
+ * ALSA driver for the Aureal Vortex family of soundprocessors.
+ * Author: Manuel Jander (mjander@embedded.cl)
+ *
+ *   This driver is the result of the OpenVortex Project from Savannah
+ * (savannah.nongnu.org/projects/openvortex). I would like to thank
+ * the developers of OpenVortex, Jeff Muizelaar and Kester Maddock, from
+ * whom i got plenty of help, and their codebase was invaluable.
+ *   Thanks to the ALSA developers, they helped a lot working out
+ * the ALSA part.
+ *   Thanks also to Sourceforge for maintaining the old binary drivers,
+ * and the forum, where developers could comunicate.
+ *
+ * Now at least i can play Legacy DOOM with MIDI music :-)
