I looked into the x86 side a bit.  I'm pretty sure we can just remove
the _safe variants.  All they do is spew warnings that don't seem to be
doing any good.  They're not really safer in any meaningful way.

I've got a series cooked up to zap them, but I need to get some eyeballs
on it.

But if Andrew wants to pick this up any carry it in the meantime since
it's cross-arch I'm fine with it:
