As I mentioned in another reply, we should not be using packed.

Packed has other implications, which makes it use byte-at-a-time accesses
for all parts of a structure when you tag it with 'packed'.  GCC doesn't
try to be clever and see that actually such accesses are safe.

If plain "__long_aligned" works and, since you're tagging it to the structure
definition, it only specifies a minimum-alignment, then I'm fine with using
that to fix this.
