main/linux-grsec: add armhf config, and cherry-pick few arm fixes
- platform of/modalias patch is needed for our initramfs to work
properly
- imx6q unclocked sleep is to fix ethernet performance issues on
wandboard - the nic cannot wakeup from unclocked sleep. the
proper way is to reroute that irq to alternate pin, but those
patches do not exist for this new kernels.
