Subject[GIT PULL] KEYS: Fixes and crypto fixes
Hi James,

Can you pull these and pass them on to Linus. There are two sets of
patches here:

(1) A bunch of core keyrings bug fixes from Eric Biggers.

(2) Fixing big_key to use safe crypto from Jason A. Donenfeld.

There are more patches to come from Eric, but I haven't reviewed at them
yet, so I haven't included them here. Thanks to Eric for reviewing the
keyrings code.

The following changes since commit ebb2c2437d8008d46796902ff390653822af6cc4:
