<lkft@...aro.org> These patches are just flat out not worth it anymore, we have had more problems with them over the past few months than I can remember ever having for any other backport. Francis, I'm sorry, but I give up here, I'm dropping these from all queues again, and if you feel they need to get into an older kernel tree like these, please submit the needed changes to the device/vendor/whomever trees as they can deal with the fallout, this has caused too many problems for the LTS kernels... thanks, greg k-h
