Linux-2.6.12-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!

[PATCH] i2c-viapro: Some adjustments The big i2c-viapro SMBus driver update which went into 2.6.14-git1 introduced a few minor issues. Nothing critical, but I would like a few adjustments to be merged in to fix the following problems: * VIA should not be spelled Via. * Frodo Looijaard and Philip Edelbrock did not write the i2c-viapro driver. * When debugging is disabled, half of messages would be logged. * Drop an unneeded masking. * Some port reads can be avoided now that the transaction size is passed as a parameter to vt596_transaction(). * SMBus Receive Byte transactions are used for probing too (for EEPROMs), so hide errors on these too.

[PATCH] i2c-viapro: Implement I2C Block transactions Implement the I2C block transactions on VIA chips which support them: VT82C686B, VT8233, VT8233A, VT8235 and VT8237R. This speeds up EEPROM accesses by a factor 10 or so. I would like to thank Antonino A. Daplas, Hinko Kocevar, Salah Coronya and Andreas Henriksson for their help in testing this new feature.

Except for the oldest chips (VT82C596A/B, VT82C686A and most probably
VT8231), this driver supports I2C block transactions. Such transactions
are mainly useful to read from and write to EEPROMs.

this driver doesn't implement it yet.
