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!

+config SND_TIMER

+
+config SND_PCM
+	tristate
+	select SND_TIMER
+	depends on SND
+
+config SND_HWDEP
+	tristate

+
+config SND_RAWMIDI
+	tristate
+	depends on SND
+
+config SND_SEQUENCER
+	tristate "Sequencer support"
+	depends on SND
+	select SND_TIMER
+	help
+	  Say Y or M to enable MIDI sequencer and router support.  This
+	  feature allows routing and enqueueing of MIDI events.  Events
+	  can be processed at a given time.
+
+	  Many programs require this feature, so you should enable it
+	  unless you know what you're doing.
+
+config SND_SEQ_DUMMY
+	tristate "Sequencer dummy client"
+	depends on SND_SEQUENCER
+	help
+	  Say Y here to enable the dummy sequencer client.  This client
+	  is a simple MIDI-through client: all normal input events are
+	  redirected to the output port immediately.
+
+	  You don't need this unless you want to connect many MIDI
+	  devices or applications together.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called snd-seq-dummy.
+
+config SND_OSSEMUL
+	bool
+	depends on SND
+
+config SND_MIXER_OSS
+	tristate "OSS Mixer API"
+	depends on SND
+	select SND_OSSEMUL
+	help
+	  To enable OSS mixer API emulation (/dev/mixer*), say Y here
+	  and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.
+
+	  Many programs still use the OSS API, so say Y.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called snd-mixer-oss.
+
+config SND_PCM_OSS
+	tristate "OSS PCM (digital audio) API"
+	depends on SND
+	select SND_OSSEMUL
+	select SND_PCM
+	help
+	  To enable OSS digital audio (PCM) emulation (/dev/dsp*), say Y
+	  here and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.
+
+	  Many programs still use the OSS API, so say Y.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called snd-pcm-oss.
+
+config SND_SEQUENCER_OSS
+	bool "OSS Sequencer API"
+	depends on SND && SND_SEQUENCER
+	select SND_OSSEMUL
+	help
+	  Say Y here to enable OSS sequencer emulation (both
+	  /dev/sequencer and /dev/music interfaces).
+
+	  Many programs still use the OSS API, so say Y.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called snd-seq-oss.
+
+config SND_RTCTIMER
+	tristate "RTC Timer support"
+	depends on SND && RTC
+	select SND_TIMER
+	help
+	  Say Y here to enable RTC timer support for ALSA.  ALSA uses
+	  the RTC timer as a precise timing source and maps the RTC
+	  timer to ALSA's timer interface.  The ALSA sequencer code also
+	  can use this timing source.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called snd-rtctimer.
+
+config SND_VERBOSE_PRINTK
+	bool "Verbose printk"
+	depends on SND
+	help
+	  Say Y here to enable verbose log messages.  These messages
+	  will help to identify source file and position containing
+	  printed messages.
+
+	  You don't need this unless you're debugging ALSA.
+
+config SND_DEBUG
+	bool "Debug"
+	depends on SND
+	help
+	  Say Y here to enable ALSA debug code.
+
+config SND_DEBUG_MEMORY
+	bool "Debug memory"
+	depends on SND_DEBUG
+	help
+	  Say Y here to enable debugging of memory allocations.
+
+config SND_DEBUG_DETECT
+	bool "Debug detection"
+	depends on SND_DEBUG
+	help
+	  Say Y here to enable extra-verbose log messages printed when
+	  detecting devices.
+
+config SND_GENERIC_PM
+	bool
+	depends on SND
