What this means is that we're going to end up littering things like GIC and other stuff with lots of individual SoC specific code to save state into individual SoC specific structures. This is not sane, and we're not going to corrupt generic code with SoC specific code. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
