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).
