Linux 3.10 is a bit special in that it's been designated as receiving long term maintenance, with a projected EOL of September, 2015. My hope is that as I-pipe patches become available for newer kernel releases, some level of continued engineering can be applied to providing an occasional update to I-pipe for ARM for 3.10.x. For example, x = 23 as of this writing. Thanks. Best Regards, Mitch
