I'd like it to if at all possible; it's all pretty much Tegra-specific 
drivers so shouldn't cause any fallout for other platforms. The only 
exception is the fdt_translate_address() changes, which are a 
dependency, which will be built into other platforms, but there's a 
simple Boolean parameter that controls the new behaviour, so it should 
be pretty safe.
