Public bug reported: 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 smoothly to 7.0. Fix: All these patches are already upstream (in 7.1) except the last one. Testcase: 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.
