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!

+config GAMEPORT
+	tristate "Gameport support"
+	---help---
+	  Gameport support is for the standard 15-pin PC gameport. If you
+	  have a joystick, gamepad, gameport card, a soundcard with a gameport
+	  or anything else that uses the gameport, say Y or M here and also to
+	  at least one of the hardware specific drivers.
+
+	  For Ensoniq AudioPCI (ES1370), AudioPCI 97 (ES1371), ESS Solo1,
+	  S3 SonicVibes, Trident 4DWave, SiS7018, and ALi 5451 gameport
+	  support is provided by the sound drivers, so you won't need any
+	  from the below listed modules. You still need to say Y here.
+
+	  If unsure, say Y.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called gameport.

+# Yes, SOUND_GAMEPORT looks a bit odd. Yes, it ends up being turned on

+# unusual dependency between GAMEPORT and sound drivers.
+#
+# Some sound drivers call gameport functions. If GAMEPORT is
+# not selected, empty stubs are provided for the functions and all is
+# well.
+# If GAMEPORT is built in, everything is fine.
+# If GAMEPORT is a module, however, it would need to be loaded for the
+# sound driver to be able to link properly. Therefore, the sound
+# driver must be a module as well in that case. Since there's no way
+# to express that directly in Kconfig, we use SOUND_GAMEPORT to
+# express it. SOUND_GAMEPORT boils down to "if GAMEPORT is 'm',
+# anything that depends on SOUND_GAMEPORT must be 'm' as well. if
+# GAMEPORT is 'y' or 'n', it can be anything".
