I think you can/should just use the natural alignment for "u64".

For architectures that need 8-byte alignment, u64 will already be
properly aligned. For architectures (like x86-32) that only need
4-byte alignment, you get it.

I should have added mention of that with my previous email. For the
parameters that are always a multiple of u64 -- namely, the key -- I
now do that in v5 of the patchset. So this is already done.
