    Here it would be good to have a more detailed explanation about the alignment
    trap handling. I remember discussing it with you before, but don't remember
    the exact outcome. In particular you should explain here why you need to
    handle alignment traps in the first place, and what the expected defaults
    are (e.g. always disabled unless a user requests it, or always enabled) and
    what kind of code runs into the traps (e.g. buggy kernel code, correct
    kernel code, buggy user space code etc).
