Where will this patch be merged?

It probably won't happen for 3.8, but that config fragment will move to
arch/arm/mach-tegra/Kconfig when Tegra enables single zImage support, I
believe. So, it'd be good to make sure this patch gets merged somewhere
that could be used as a baseline for other arm-soc branches if needed,
to avoid merge conflicts.
