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.
