Please see http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/072446.html Instead of having CONFIG_ARCH_DMA_ADDR_T_64BIT=y in the defconfig, I guess selecting it from Kconfig makes more sense: diff --git a/arch/arm/mach-imx/Kconfig b/arch/arm/mach-imx/Kconfig index 573536f1bb73..bb417e73af0f 100644 --- a/arch/arm/mach-imx/Kconfig +++ b/arch/arm/mach-imx/Kconfig @@ -563,6 +563,7 @@ config SOC_LS1021A select HAVE_ARM_ARCH_TIMER select PCI_DOMAINS if PCI select ZONE_DMA if ARM_LPAE + select ARCH_DMA_ADDR_T_64BIT help This enables support for Freescale LS1021A processor.
