Modules: SB drivers,ALS4000 driver
some update for the ALS4000 driver (tested with hardware in my PC):
- use common control names according to ControlNames.txt

- optimize struct snd_card_als4000_t layout (performance/size)
- save some bytes via unified error path
- constify some read-only data
- add ToDo list
- move GPL license text to top
- add comments

Modules: AC97 Codec
Remove the definition of ac97_enum struct from the public ac97_codec.h.
It's used only in the module.
The location of struct ac97_pcm is moved closer to its accessor
to improve readability.

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.

In commit 3D59121003721a8fad11ee72e646fd9d3076b5679c, the x86 and x86-64
<asm/param.h> was changed to include <linux/config.h> for the
configurable timer frequency.
However, asm/param.h is sometimes used in userland (it is included
indirectly from <sys/param.h>), so your commit pollutes the userland
namespace with tons of CONFIG_FOO macros. This greatly confuses
software packages (such as BusyBox) which use CONFIG_FOO macros
themselves to control the inclusion of optional features.
After a short exchange, Christoph approved this patch

Some G5s still occasionally experience shutdowns due to overtemp
conditions despite the recent fix. After analyzing logs from such
machines, it appears that the overtemp code is a bit too quick at
shutting the machine down when reaching the critical temperature (tmax +
8) and doesn't leave the fan enough time to actually cool it down. This
happens if the temperature of a CPU suddenly rises too high in a very
short period of time, or occasionally on boot (that is the CPUs are
already overtemp by the time the driver loads).
This patches makes the code a bit more relaxed, leaving a few seconds to
the fans to do their job before kicking the machine shutown.

This is a slightly more complete fix for the previous minimal sysctl
string fix. It always terminates the returned string with a NUL, even
if the full result wouldn't fit in the user-supplied buffer.
The returned length is the full untruncated length, so that you can
tell when truncation has occurred.

For the sysctl syscall, if the user wants to get the old value of a
sysctl entry and set a new value for it in the same syscall, the old
value is always overwritten by the new value if the sysctl entry is of
string type and if the user sets its strategy to sysctl_string. This
issue lies in the strategy being run twice if the strategy is set to
sysctl_string, the general strategy sysctl_string always returns 0 if
success.
Such strategy routines as sysctl_jiffies and sysctl_jiffies_ms return 1
because they do read and write for the sysctl entry.
The strategy routine sysctl_string return 0 although it actually read
and write the sysctl entry.
According to my analysis, if a strategy routine do read and write, it
should return 1, if it just does some necessary check but not read and
write, it should return 0, for example sysctl_intvec.

If the string was too long to fit in the user-supplied buffer,
the sysctl layer would zero-terminate it by writing past the
end of the buffer. Don't do that.

The old /proc interfaces were never updated to use loff_t, and are just
generally broken. Now, we should be using the seq_file interface for
all of the proc files, but converting the legacy functions is more work
than most people care for and has little upside..
But at least we can make the non-LFS rules explicit, rather than just
insanely wrapping the offset or something.
