Sorry for the broken ordering and missing cover letter. 
I just submitted three crypto patches:

[PATCH 1/4] crypto: sunxi - don't print uninitialized data
[PATCH] crypto: hash - select CRYPTO_HASH where needed
[PATCH 1/2] crypto: jitterentropy - always select CRYPTO_RNG

These address independent build issues, and there is no ordering between
them. None of them are important, so please queue them up for 4.6.
