I guess they must be in linux-next, since this series applies cleanly on top of it. So, patches 2/16 ("ARM: l2c: add platform independent core L2 cache initialisation") and 7/16 ("ARM: l2c: convert tegra to generic l2c initialisation"), Tested-by: Stephen Warren <swarren@xxxxxxxxxx> (On an NVIDIA Tegra20 Seaboard/Springbank board, on top of next-20140428) I do see one error in dmesg during boot, but it doesn't appear to negatively affect operation in brief testing, and is present in linux-next without this series anyway.
