In that case I am a bit confused by the following result: # git checkout v3.6 # ARCH=arm make omap2plus_defconfig # grep '(SOC_OMAP5|_SCU|_TWD|CONFIG_SMP|CONFIG_LOCAL_TIMERS)=' .config CONFIG_SOC_OMAP5=y CONFIG_SMP=y CONFIG_HAVE_ARM_SCU=y CONFIG_HAVE_ARM_TWD=y CONFIG_LOCAL_TIMERS=y -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
