Hmm? These don't seem right. It also has a weird code sequence:

Did something go wrong there?

Yes, I fixed those up after doing some allmodconfig builds.

Here is the final patch I actually pushed to Linus:

That fixes up the sg_mark_end() bit, but it's still calling
sg_init_table() just a few lines further down. Is that correct?

Absolutely.  It initially using the scatterlist for this
crypto layer call:

	ret = crypto_blkcipher_decrypt_iv(&desc->desc, desc->frags,
					  desc->frags, thislen);
	if (ret)
		return ret;

then it reinits and sets the sglist to the values the caller
wants.
