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!

+ * for more info.
+ *
+ *
+ *      The OPL-3 mode is switched on by writing 0x01, to the offset 5
+ *      of the right side.
+ *
+ *      Another special register at the right side is at offset 4. It contains
+ *      a bit mask defining which voices are used as 4 OP voices.
+ *
+ *      The percussive mode is implemented in the left side only.
+ *
+ *      With the above exceptions the both sides can be operated independently.
+ *      
+ *      A 4 OP voice can be created by setting the corresponding
+ *      bit at offset 4 of the right side.
+ *
+ *      For example setting the rightmost bit (0x01) changes the
+ *      first voice on the right side to the 4 OP mode. The fourth
+ *      voice is made inaccessible.
+ *
+ *      If a voice is set to the 2 OP mode, it works like 2 OP modes
+ *      of the original YM3812 (AdLib). In addition the voice can 
+ *      be connected the left, right or both stereo channels. It can
+ *      even be left unconnected. This works with 4 OP voices also.
+ *
+ *      The stereo connection bits are located in the FEEDBACK_CONNECTION
+ *      register of the voice (0xC0-0xC8). In 4 OP voices these bits are
+ *      in the second half of the voice.
