I suspect anything that has the SHA extensions should also do
unaligned loads efficiently. The whole "aligned only" model is broken.
It's just doing two loads from the state pointer, there's likely no
point in trying to align it.

So your patch looks fine, but maybe somebody could add the required
alignment to the sha256 context allocation (which I don't know where
it is).

But yeah, that other SLOB panic looks unrelated to this.
