get_unaligned - get value from possibly mis-aligned location : pointer to value

This macro should be used for accessing values larger in size than single bytes at locations that are expected to be improperly aligned, e.g. retrieving a u16 value from a location not u16-aligned.

Note that unaligned accesses can be very expensive on some architectures.

put_unaligned - put value to a possibly mis-aligned location : value to place : pointer to location

This macro should be used for placing values larger in size than single bytes at locations that are expected to be improperly aligned, e.g. writing a u16 value to a location not u16-aligned.

Note that unaligned accesses can be very expensive on some architectures.
