The Linux kernel assumes and requires that a processor handles alignment faults and fixups in kernel space.
This is done because there are many cases where an object is almost always aligned and it is faster to assume alignment than to mess around with every single chunk of data. Its tuned so those alignment traps should not be occurring at a high rate.
