I don't think this solution would be valid on many other platforms. It forces the structure to not be padded, and
assumesthat the cpu will be able to fetch from unaligned boundaries. The only reason this works is that the arm linux
kernelcontains an alignment trap handler that catches the fault and does a fixup on the access. Otherwise it would
crashwith SIGBUS.

Well, this patch seems to produce attlens of 6 as desired, but it causes many (13) of the regression tests to fail. Do
youwant to see the regression.diffs?
