Buglink: https://bugs.launchpad.net/bugs/2162871

SRU Justification:

[Impact]

This is a patchset that we (TUXEDO Computers) currently apply on top of the Ubuntu 7.0 kernel to make it run smoothly on all our devices. All patches apply without conflicts to 7.0.

[Fix]

All these patches are already upstream.

[Test Plan]

We run this patchset for all our customers devices (we basically maintain our own OEM branch) so it is quite field testet. Besides that, whenever a new patch was added we did regression testing on a selection of devices.

[Where problems could occur]

The docking station fix is applying a big patchset from 7.1 to 7.0 that is to big for stable, but I think that the Ubuntu kernel could imensly profit from the better, less buggy docking station handling it provides.
