Newer versions of gcc generate unaligned accesses by default, causing

This description doesn't make sense.  If we have alignment traps enabled,
then we _expect_ to fix up unaligned loads and stores.

Therefore there should be no panic if CONFIG_ALIGNMENT_TRAP is enabled.

So what's the _actual_ problem that this is trying to address?  What's
the panic/oops look like?  And that information should be in the commit
description _anyway_.
