If there are no objections, I can take it through samsung-soc with other arch/arm/mach-exynos* patches. What I am missing here, is Matthew's Signed-off-by. Matthew, you touched and sent the patch so could you add the Sob?

Either that or I could just send it from my tree directly.

I've asked Matthew to re-send the core patches with the signed-off sorted out. He can also put them on a public facing git server if that would be helpful.

Thanks. > He can also put them on a public facing git server if > that would be helpful. No need. I think it will go through separate trees anyway. Except the change adding ARCH_SUPPORTS_BIG_ENDIAN, I don't see any dependencies. As for the ARCH_SUPPORTS_BIG_ENDIAN, I think it should be applied when all necessary drivers are fixed.
