2010-03-02be2net: fix tx completion pollingSathya Perla
In tx/mcc polling, napi_complete() is being incorrectly called before reaping tx completions. This can cause tx compl processing to be scheduled on another cpu concurrently which can result in a panic. This if fixed by calling napi complete() after tx/mcc compl processing but before re-enabling interrupts (via a cq notify).

2010-03-02i2c: Separate Kconfig option for i2c-smbusJean Delvare
Having a separate Kconfig option for i2c-smbus makes it possible to build that support as a module even when i2c-core itself is built-in. Bus drivers which implement SMBus alert should select this option, so in most cases this option is hidden and the user doesn't have to care about it.

2010-03-02i2c: Add SMBus alert supportJean Delvare
SMBus alert support. The SMBus alert protocol allows several SMBus slave devices to share a single interrupt pin on the SMBus master, while still allowing the master to know which slave triggered the interrupt. This is based on preliminary work by David Brownell. The key difference between David's implementation and mine is that his was part of i2c-core, while mine is split into a separate, standalone module named i2c-smbus. The i2c-smbus module is meant to include support for all SMBus extensions to the I2C protocol in the future. The benefit of this approach is a zero cost for I2C bus segments which do not need SMBus alert support. Where David's implementation increased the size of struct i2c_adapter by 7% (40 bytes on i386), mine doesn't touch it. Where David's implementation added over 150 lines of code to i2c-core (+10%), mine doesn't touch it. The only change that touches all the users of the i2c subsystem is a new callback in struct i2c_driver (common to both implementations.) I seem to remember Trent was worried about the footprint of David'd implementation, hopefully mine addresses the issue.

2010-03-01sata_via: Delay on vt6420 when starting ATAPI DMA writeBart Hartgers
When writing a disc on certain lite-on dvd-writers (also rebadged as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends up in the datastream and on the disc, causing silent corruption. Delaying between sending the CDB and starting DMA seems to prevent this. I do not know if there are burners that do not suffer from this, but the patch should be safe for those as well. There are many reports of this issue, but AFAICT no solution was found before.
