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!

34 | * 08/20/00 trw - silence and no stopping DAC until release | ||
35 | * 08/23/00 trw - added CS_DBG statements, fix interrupt hang issue on DAC stop. | ||
36 | * 09/18/00 trw - added 16bit only record with conversion | ||
37 | * 09/24/00 trw - added Enhanced Full duplex (separate simultaneous | ||
38 | * capture/playback rates) | ||
39 | * 10/03/00 trw - fixed mmap (fixed GRECORD and the XMMS mmap test plugin | ||
40 | * libOSSm.so) | ||
41 | * 10/11/00 trw - modified for 2.4.0-test9 kernel enhancements (NR_MAP removal) | ||
42 | * 11/03/00 trw - fixed interrupt loss/stutter, added debug. | ||
43 | * 11/10/00 bkz - added __devinit to cs4281_hw_init() | ||
44 | * 11/10/00 trw - fixed SMP and capture spinlock hang. | ||
45 | * 12/04/00 trw - cleaned up CSDEBUG flags and added "defaultorder" moduleparm. | ||
46 | * 12/05/00 trw - fixed polling (myth2), and added underrun swptr fix. | ||
47 | * 12/08/00 trw - added PM support. | ||
48 | * 12/14/00 trw - added wrapper code, builds under 2.4.0, 2.2.17-20, 2.2.17-8 | ||
49 | * (RH/Dell base), 2.2.18, 2.2.12. cleaned up code mods by ident. | ||
50 | * 12/19/00 trw - added PM support for 2.2 base (apm_callback). other PM cleanup. | ||
51 | * 12/21/00 trw - added fractional "defaultorder" inputs. if >100 then use | ||
52 | * defaultorder-100 as power of 2 for the buffer size. example: | ||
53 | * 106 = 2^(106-100) = 2^6 = 64 bytes for the buffer size. | ||
