Kernel
Required kernel options are now available in https://github.com/lbt/mer-kernel-check/. This git tree has also been packaged to rpm package that is available in mer core. The package is called mer-kernel-checks, which is also used in the kernel packaging template available at https://github.com/lbt/mer-kernel-adaptation
Patches
When compiling kernel for ARM with Mer 0.20110105.1 or newer
NOTE: Kernels newer than 3.4 seem to have fix for this error already thus, this patchs isn't needed.
You will need to apply this patch to your kernel with this new Mer and toolchain release, if your kernels break on boot (they likely will). It will enable -mno-unaligned-access in your kernel compilation flags.

This patch needs adding to stop systemd journal taking 100% cpu and also other features
This small patch needs applying for proper CGROUPS support
