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!

+ *  Copyright (c) 2004 James Courtier-Dutton <James@superbug.demon.co.uk>
+ *  Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
+ *  Version: 0.0.22
+ *
+ *  FEATURES currently supported:
+ *    Front, Rear and Center/LFE.
+ *    Surround40 and Surround51.
+ *    Capture from MIC an LINE IN input.
+ *    SPDIF digital playback of PCM stereo and AC3/DTS works.
+ *    (One can use a standard mono mini-jack to one RCA plugs cable.
+ *     or one can use a standard stereo mini-jack to two RCA plugs cable.
+ *     Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
+ *    ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
+ *    Notes on how to capture sound:
+ *      The AC97 is used in the PLAYBACK direction.
+ *      The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
+ *      So, to record from the MIC, set the MIC Playback volume to max,
+ *      unmute the MIC and turn up the MASTER Playback volume.
+ *      So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
+ *   
+ *    The only playback controls that currently do anything are: -
+ *    Analog Front
+ *    Analog Rear
+ *    Analog Center/LFE
+ *    SPDIF Front
+ *    SPDIF Rear
+ *    SPDIF Center/LFE
+ *   
+ *    For capture from Mic in or Line in.
+ *    Digital/Analog ( switch must be in Analog mode for CAPTURE. )
+ * 
+ *    CAPTURE feedback into PLAYBACK
+ * 
+ *  Changelog:
+ *    Support interrupts per period.
+ *    Removed noise from Center/LFE channel when in Analog mode.
+ *    Rename and remove mixer controls.

+ *  0.0.11
+ *    Add Model name recognition.
+ *  0.0.12
