With CONFIG_CPU_V7 disabled, but i.MX3 and SMP enabled, we get this build error: arch/arm/mach-imx/built-in.o: In function `v7_secondary_startup': :(.text+0x5124): undefined reference to `v7_invalidate_l1' This puts the code inside of an "ifdef CONFIG_SOC_IMX6" to hopefully do the right thing in all configurations.
