The outer_disable() of Tegra's suspend code is open-coded now since that helper produces spurious warning message about secondary CPUs being online. The secondaries are actually halted by the cpuidle driver on entering into LP2 idle-state. This fixes a storm of warnings once LP2 idling state is enabled on Tegra30.
