Merge tag 'integrity-v6.0' of git://git./linux/kernel/git/zohar/linux-integrity

Pull integrity updates from Mimi Zohar:
 "Aside from the one EVM cleanup patch, all the other changes are kexec
  related.

  On different architectures different keyrings are used to verify the
  kexec'ed kernel image signature. Here are a number of preparatory
  cleanup patches and the patches themselves for making the keyrings -
  builtin_trusted_keyring, .machine, .secondary_trusted_keyring, and
  .platform - consistent across the different architectures"
