Early on, I backported a number of performance patches to -stable with the view to having a good baseline to compare a new mainline release with. However, after a while some of them required unrelated backports that would be excessive for -stable. While I could have continued backporting some patches, I stopped as the time required to run all of the performance tests is excessive and I was already tracking too many kernels.
