Well thanks everyone.
I now understand what's going on during theses accesses.
Before today, I just always wrote my drivers/prog so that data are
aligned without asking questions. Now, i'm trying to optimize ffmpeg and
there are memory accesses that just can't be aligned and are currently
handled by the trap handler and that's bad ;) So I'm just gonna handle
alignment myself in userspace.
