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@nvidia•com>
(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. Is this message a problem?
