[ALSA] usb-audio: double-buffer all playback data
USB generic driver
We always had to use double buffering when capturing, and when playback
data for one URB crosses a buffer boundary. The latter would make hwptr
updates less precise because the double-buffered data is read from the
buffer much earlier than the other data is read by the host controller.
Double-buffering all data allows to update hwptr immediately after the
data was copied to the USB buffer(s), which has the additional benefit
of avoiding the latency imposed by the host controller's delay of up to
one frame when interrupting.

[ALSA] usb-audio: optimize handling of capture URBs
USB generic driver
When preparing capture URBs, we don't need to stop when we cross a
period boundary because we now never handle more than one millisecond of
data per URB anyway.
When handling captured data, use an extra flag to call
snd_pcm_period_elapsed() no more than once. This allows us to move the
period boundary checking code before the copying of the data which
avoids a second locking of the substream's lock.

'I would like to know what people think of the following patch. It
allows for a codec on an AC97 bus to be shared with other drivers which
are completely unrelated to audio. It registers a new bus type, and
whenever a codec instance is created then a device for it is also
registered with the driver model using that bus type. This allows, for
example, to use the extra features of the UCB1400 like the touchscreen
interface and the additional GPIOs and ADCs available on that chip for
battery monitoring. I have a working UCB1400 touchscreen driver here
that simply registers with the driver model happily working alongside
with audio features using this.'
Changes over RFC:-
o Now matches codec name within codec group.
o Added ac97_dev_release() to stop kernel complaining about no release
method for device.
o Added 'config SND_AC97_BUS' to sound/pci/Kconfig and moved 'config

[PATCH] Lazy page table copies in fork()
Defer copying of ptes until fault time when it is possible to reconstruct
the pte from backing store. Idea from Andi Kleen and Nick Piggin.
Thanks to input from Rik van Riel and Linus and to Hugh for correcting
my blundering.
Ray Fucillo <fucillo@intersystems.com> reports:
"I applied this latest patch to a 2.6.12 kernel and found that it does
resolve the problem. Prior to the patch on this machine, I was
seeing about 23ms spent in fork for ever 100MB of shared memory

After applying the patch, fork is taking about 1ms regardless of the

This makes the send rate calculations behave way more closely to what
is specified, with the jitter previously seen on x and x_recv
disappearing completely on non lossy setups.
This resembles the tcp_data_snd_check code, that possibly we'll end up

inet_connection_sock.

This speeds up link-up time on 5706 SerDes if the link partner does
not autoneg, a rather common scenario in blade servers. Some blade
servers use IPMI for keyboard input and it's important to minimize
link disruptions.
The speedup is achieved by shortening the timer to (HZ / 3) during
the transient period right after initiating a SerDes autoneg. If
autoneg does not complete, parallel detect can be done sooner. After
the transient period is over, the timer goes back to its normal HZ
interval.
As suggested by Jeff Garzik, the timer initialization is moved to
bnx2_init_board() from bnx2_open().
An eeprom bit is also added to allow default forced SerDes speed for
even faster link-up time.

The fix is to set a flag if we are in the reset task which is run

As suggested by Jeff Garzik, the loop is changed to call msleep(1)
