Subject: [GIT PULL] Security subystem fixes for v4.14-rc5

This includes a fix for the capabilities code from Colin King, and a set 
of further fixes for the Keys subsystem.  From David:

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

 (2) Fix some ecryptfs bits.

 (3) Fix big_key to require CONFIG_CRYPTO.

 (4) Fix a couple of bugs in the asymmetric key type.

 (5) Fix a race between updating and finding negative keys.

 (6) Prevent add_key() from updating uninstantiated keys.

 (7) Make loading of key flags and expiry time atomic when not holding 
     locks."

Please pull!
