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!

+ *  azt3328.c - driver for Aztech AZF3328 based soundcards (e.g. PCI168).
+ *  Copyright (C) 2002 by Andreas Mohr <hw7oshyuv3001@sneakemail.com>
+ *
+ *  Framework borrowed from Bart Hartgers's als4000.c.
+ *  Driver developed on PCI168 AP(W) version (PCI rev. 10, subsystem ID 1801),
+ *  found in a Fujitsu-Siemens PC ("Cordant", aluminum case).
+ *  Other versions are:
+ *  PCI168 A(W), sub ID 1800
+ *  PCI168 A/AP, sub ID 8000
+ *  Please give me feedback in case you try my driver with one of these!!

+ *
+ * NOTES
+ *  Since Aztech does not provide any chipset documentation,
+ *  even on repeated request to various addresses,
+ *  and the answer that was finally given was negative
+ *  (and I was stupid enough to manage to get hold of a PCI168 soundcard
+ *  in the first place >:-P}),
+ *  I was forced to base this driver on reverse engineering
+ *  (3 weeks' worth of evenings filled with driver work).
+ *  (and no, I did NOT go the easy way: to pick up a PCI128 for 9 Euros)
+ *
+ *  The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
+ *  for compatibility reasons) has the following features:
+ *
+ *  - builtin AC97 conformant codec (SNR over 80dB)
+ *    (really AC97 compliant?? I really doubt it when looking
+ *    at the mixer register layout)
+ *  - builtin genuine OPL3
+ *  - full duplex 16bit playback/record at independent sampling rate
+ *  - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
+ *  - game port (legacy address support)
+ *  - built-in General DirectX timer having a 20 bits counter
+ *    with 1us resolution (FIXME: where is it?)
+ *  - I2S serial port for external DAC
+ *  - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI
+ *  - supports hardware volume control
+ *  - single chip low cost solution (128 pin QFP)
+ *  - supports programmable Sub-vendor and Sub-system ID
+ *    required for Microsoft's logo compliance (FIXME: where?)
+ *  - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
+ *
+ *  Certain PCI versions of this card are susceptible to DMA traffic underruns
+ *  in some systems (resulting in sound crackling/clicking/popping),
+ *  probably because they don't have a DMA FIFO buffer or so.
+ *  Overview (PCI ID/PCI subID/PCI rev.):
+ *  - no DMA crackling on SiS735: 0x50DC/0x1801/16
+ *  - unknown performance: 0x50DC/0x1801/10
+ *  
+ *  Crackling happens with VIA chipsets or, in my case, an SiS735, which is
+ *  supposed to be very fast and supposed to get rid of crackling much
+ *  better than a VIA, yet ironically I still get crackling, like many other
+ *  people with the same chipset.
+ *  Possible remedies:
+ *  - plug card into a different PCI slot, preferrably one that isn't shared
+ *    too much (this helps a lot, but not completely!)
+ *  - get rid of PCI VGA card, use AGP instead
+ *  - upgrade or downgrade BIOS
+ *  - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX)
+ *    Not too helpful.
+ *  - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
+ * 
+ * BUGS
+ *  - when Ctrl-C'ing mpg321, the playback loops a bit
+ *    (premature DMA playback reset?)
+ *  - full-duplex sometimes breaks (IRQ management issues?).
+ *    Once even a spontaneous REBOOT happened!!!
+ * 
+ * TODO
+ *  - test MPU401 MIDI playback etc.
+ *  - power management (CONFIG_PM). See e.g. intel8x0 or cs4281.
+ *    This would be nice since the chip runs a bit hot, and it's *required*
+ *    anyway for proper ACPI power management. In other words: rest
+ *    assured that I *will* implement this very soon; as soon as Linux 2.5.x
+ *    has power management that's bugfree enough to work properly on my desktop.
+ *  - figure out what all unknown port bits are responsible for
