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!

+ * Routines for control of 16-bit SoundBlaster cards and clones
+ * Note: This is very ugly hardware which uses one 8-bit DMA channel and
+ * second 16-bit DMA channel. Unfortunately 8-bit DMA channel can't
+ * transfer 16-bit samples and 16-bit DMA channels can't transfer
+ * 8-bit samples. This make full duplex more complicated than
+ * can be... People, don't buy these soundcards for full 16-bit
+ * duplex!!!
+ * Note: 16-bit wide is assigned to first direction which made request.
+ * With full duplex - playback is preferred with abstract layer.
+ *
+ * Note: Some chip revisions have hardware bug. Changing capture
+ * channel from full-duplex 8bit DMA to 16bit DMA will block
+ * 16bit DMA transfers from DSP chip (capture) until 8bit transfer
+ * to DSP chip (playback) starts. This bug can be avoided with
+ * "16bit DMA Allocation" setting set to Playback or Capture.
