Hey again Eric,

One thing led to another and I wound up just rewriting all the crypto
in big_keys.c. I'll include this for v4:

https://git.zx2c4.com/linux-dev/commit/?h=jd/rng-blocker&id=886ff283b9808aecb14aa8e397da8496a9635aed

Not only was the use of crypto/rng inappropriate, but the decision to
go with aes-ecb is shocking. Seeing that this author had no other
commits in the tree, and that all subsequent commits that mentioned
his name were cleaning up his mess, I just went ahead and removed both
the crypto/rng misusage and changed from aes-ecb to aes-gcm.

Anyway, I'll wait for some more reviews on v3, and then this can be
reviewed for v4.

Regards,
Jason
