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.
