Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security

Pull intgrity updates from James Morris:
 "This contains just three patches, the remainder were either included
  in other pull requests (eg. audit, lockdown) or will be upstreamed via
  other subsystems (eg. kselftests, Power).

  Included here is one bug fix, one documentation update, and extending
  the x86 IMA arch policy rules to coordinate the different kernel
  module signature verification methods"
