Dears, I have been working with embedded boards. It only supports 3.4 kernel. So, I'm trying to backport a latest bluetooth subsystem to 3.4 kernel. (I used a backports-4.1.1-1 stable release) But I could not backport because not shown 'Bluetooth subsystem support' selection. My steps is below: ###To compile old kernel $ export ARCH=arm $ export CROSS_COMPILE=$CCPREFIX $ cd $KERNEL_SRC KERNEL_SRC$ make defconfig KERNEL_SRC$ make KERNEL_SRC$ make INSTALL_MOD_PATH=$OUTPUT install ###To backport $ export KLIB=$KERNEL_SRC $ export KLIB_BUILD=$OUTPUT $ wget http://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.1.1/backports-4.1.1-1.tar.xz $ unxz backports-4.1.1-1.tar.xz $ tar xfp backports-4.1.1-1.tar $ cd backports-4.1.1-1 backports-4.1.1-1$ make menuconfig ### not shown 'Bluetooth subsystem support' selection. But, if not set a KLIB env value, shown 'Bluetooth subsystem support' selection. Am I missing some configuration? Please advise me.
