Pull security subsystem updates from James Morris.

Mostly ima, selinux, smack and key handling updates.

* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (65 commits)
  integrity: do zero padding of the key id
  KEYS: output last portion of fingerprint in /proc/keys
  KEYS: strip 'id:' from ca_keyid
  KEYS: use swapped SKID for performing partial matching
  KEYS: Restore partial ID matching functionality for asymmetric keys
  X.509: If available, use the raw subjKeyId to form the key description
  KEYS: handle error code encoded in pointer
  selinux: normalize audit log formatting
  selinux: cleanup error reporting in selinux_nlmsg_perm()
  KEYS: Check hex2bin()'s return when generating an asymmetric key ID
  ima: detect violations for mmaped files
  ima: fix race condition on ima_rdwr_violation_check and process_measurement
  ima: added ima_policy_flag variable
  ima: return an error code from ima_add_boot_aggregate()
  ima: provide 'ima_appraise=log' kernel option
  ima: move keyring initialization to ima_init()
  PKCS#7: Handle PKCS#7 messages that contain no X.509 certs
  PKCS#7: Better handling of unsupported crypto
  KEYS: Overhaul key identification when searching for asymmetric keys
  KEYS: Implement binary asymmetric key ID handling
