I did a quick smoke test for this series on top of Linus' master:
- rebuilding with the patches applied, CONFIG_ARM_TEGRA_CPUIDLE=n - works
- building with CONFIG_ARM_TEGRA_CPUIDLE=y - doesn't boot

The hang is somewhere early in the boot process, before simplefb can
take the console and show any logs. If I get BOOTFB to work again I might
be able to get some more info.
