Modules: EMU10K1/EMU10K2 driver
on Audigy 2 ZS Notebook.
Set the master volume to about 6 or 8% in alsamixer. This will
attenuate the output enough for better sound quality.
Note: Only stereo enabled at present.
The distortion is caused by the output path after the DSP
adding 12dB gain to the output while still in digital mode,
resulting in wrap around distortion.

We have found some issues with Au1550 AC'97 OSS driver in 2.6
(sound/oss/au1550_ac97.c), though it also should concern 2.4 driver
(drivers/sound/au1550_psc.c).
start_dac() grabs a spinlock already held by its caller, au1550_write().
This doesn't show up with the standard UP spinlock impelmentation but when
the different one (mutex based) is in use, a lockup happens.
And the interrupt handlers also didn't grab the spinlock -- that's OK in
the usual kernel but not when the IRQ handlers are threaded. So, they're
grabbing the spinlock now (as every correct interrupt handler should do).

Earlier I unifdefed PageCompound, so that snd_pcm_mmap_control_nopage and
others can give out a 0-order component of a higher-order page, which won't
be mistakenly freed when zap_pte_range unmaps it. But many Bad page states
reported a PG_reserved was freed after all: I had missed that we need to
say __GFP_COMP to get compound page behaviour.
Some of these higher-order pages are allocated by snd_malloc_pages, some by
snd_malloc_dev_pages; or if SBUS, by sbus_alloc_consistent - but that has
no gfp arg, so add __GFP_COMP into its sparc32/64 implementations.
I'm still rather puzzled that DRM seems not to need a similar change.

Something noticed when studying use of VM_RESERVED in different drivers:
snd_usX2Y_hwdep_pcm_vm_nopage omitted to get_page: fixed.
And how did this work before? Aargh! That nopage is returning a page from
within a buffer allocated by snd_malloc_pages, which allocates a high-order
page, then does SetPageReserved on each 0-order page within.
That would have worked in 2.6.14, because when the area was unmapped,
PageReserved inhibited put_page. 2.6.15-rc1 removed that inhibition (while
leaving ineffective PageReserveds around for now), but it hasn't caused
trouble because.. we've not been freeing from VM_RESERVED at all.

ever since suspend to disk works I had the problem that headphone
(un)plugging doesn't get detected properly anymore after the first
resume.
Reloading the module worked around this ever since, however the real
cause of the problem was that after a resume the driver only got
interrupts on "unplug" not on "plug". Reactivating the headphone status
interrupt in tumbler_resume fixes this. This shouldn't cause
any trouble with software suspend, but it would be nice if somebody
could confirm this:

This patch removes almost all inclusions of linux/version.h. The 3
#defines are unused in most of the touched files.
A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.
There are also lots of #ifdef for long obsolete kernels, this was not
touched. In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

Modules: USB generic driver
If we submit all our URBs when a playback stream is started, the first
hwptr_done update for each URB happens at the same time. This results
in an underrun when there isn't enough PCM data available at this
point for all URBs.
To avoid this, we begin submitting our URBs earlier (when the stream
is prepared), with empy packets. When the stream is started, the
prepare_playback_urb() call for each URB will be run only when the
respective URB has completed previously, so the first hwptr_done
updates will be done nicely staggered.

Modules: AZT3328 driver
this is now an even much more reworked patch (#3) for my azt3328.c ALSA driver.
IOW I spent another 4 evenings to get the sequencer timer to work properly
(my head is still hurting) and do lots of other cleanups.
Note that despite the extensive sequencer timer additions, the driver object
is still only 2kB bigger than the previous version, due to those many
optimizations...
Changes in version #3:
- fully working ALSA sequencer timer support for the card's 1024000Hz
DirectX timer (downscaling adjustable via seqtimer_scaling module param)
- an insane amount of code optimizations
- many, many cleanups
Changes in version #2:
- FOUND the 1us DirectX timer area (yay!), made the code respect it
properly
- renamed some 'weird' mixer control names according to ControlNames.txt
- cleanup unneeded debug messages, reformatting
- improved I/O register documentation
- constified many more structs
Changes in version #1:
- improves/fixes some fatal playback/recording interaction
- improves IRQ handler performance (and actually fixes some weird code)
- coalesces some I/O accesses
- slightly improves I/O interface documentation
- improves/fixes logging
- defines out some less important debug code
- constifies some data
