Pull key handling fixes from James Morris:
 "This includes a fix for the capabilities code from Colin King, and a
  set of further fixes for the keys subsystem. From David:

   - Fix a bunch of places where kernel drivers may access revoked
     user-type keys and don't do it correctly.

   - Fix some ecryptfs bits.

   - Fix big_key to require CONFIG_CRYPTO.

   - Fix a couple of bugs in the asymmetric key type.

   - Fix a race between updating and finding negative keys.

   - Prevent add_key() from updating uninstantiated keys.

   - Make loading of key flags and expiry time atomic when not holding
     locks"
