Being spoilt by the luxuries of i386/x86_64 I've never really had a good
grasp on unaligned memory access problems on other architectures and decided
it was time to figure it out. As a result I've written this documentation
which I plan to submit for inclusion as
Documentation/unaligned_memory_access.txt
Before I do so, any comments on the following?

You may be wondering why you have never seen these problems on your own
architecture. Some architectures (such as i386 and x86_64) do not have this
limitation, but nevertheless it is important for you to write portable code
that works everywhere.
Also, x86 doesn't prohibit unaligned accesses, but I believe they have a
significant performance cost and are best avoided where possible.
