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!

17 * The AD1848 codec has generic input lines called Line, Aux1 and Aux2.
18 * Sound card manufacturers have connected actual inputs (CD, synth, line,
19 * etc) to these inputs in different order. Therefore it's difficult
20 * to assign mixer channels to these inputs correctly. The following
21 * contains two alternative mappings. The first one is for GUS MAX and
22 * the second is just a generic one (line1, line2 and line3).
23 * (Actually this is not a mapping but rather some kind of interleaving
24 * solution).
