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!

+     To over come this, samples are copied into the tram and a special dsp patch copies

+     (including the emu10k2 (audigy)). This allows us to use the regular, and much simpler
+     playback method.

+
+  In both methods, dsp code is used to mux audio and passthrough. This ensures that the spdif
+  doesn't receive audio and pasthrough data at the same time. The spdif flag SPCS_NOTAUDIODATA
