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

Pull security subsystem integrity updates from James Morris:
 "There is a mixture of bug fixes, code cleanup, preparatory code for
  new functionality and new functionality.

  Commit 26ddabfe96bb ("evm: enable EVM when X509 certificate is
  loaded") enabled EVM without loading a symmetric key, but was limited
  to defining the x509 certificate pathname at build. Included in this
  set of patches is the ability of enabling EVM, without loading the EVM
  symmetric key, from userspace. New is the ability to prevent the
  loading of an EVM symmetric key."
