For what I see, that's based on the tradeoff between space and contention -
for instance there are few zones only, so there's no big waste. In practice,
interpreting !X86_GENERIC as "I will run this kernel on _this_ processor"
could also be done.
However, in case you didn't note, max_align is never enough on EM64T
currently, right?
