--- Comment #12 from Stefan Ring <stefanrin at gmail dot com> ---
Unfortunately my armv5 device has died in the meantime, so I cannot verify my
original use case. The behavior is indeed different on armv7. It does not trap,
even for the original misaligned code. And contrary to x86, where the alignment
check flag can be changed by user space, this is a privileged operation on arm,
so I cannot even selectively enable it.
