i have not done any measurements. the spinlock_t stuff is needed since
we've agreed that the attribute((aligned(16)) is not sufficient to
guarantee correct alignment. the atomic-lock optimization is based on
some discussions we had a few months ago. i'd like to actually try
these, but we still don't have a bootable SMP kernel yet :(
