[meta-freescale] ERROR when loading oprofile.ko for imx6qsabresd

[jojo]

My steps is following :

	1. enable configure of kconfig in ~/imx6q/rootfs_builder/sources/meta-fsl-arm/recipes-kernel/linux/linux-imx-3.0.35/mx6/defconfig
		CONFIG_PROFILING=y
		CONFIG_OPROFILE=m

Please see output below that was generated by loading oprofile.ko to build fsl-image-gui

Any suggestions ? are there any patches for this issue ? thanks.
