Merge tag 'integrity-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity

Pull integrity subsystem updates from Mimi Zohar:
 "The large majority of the changes are EVM portable & immutable
  signature related: removing a dependency on loading an HMAC key,
  safely allowing file metadata included in the EVM portable & immutable
  signatures to be modified, allowing EVM signatures to fulfill IMA file
  signature policy requirements, including the EVM file metadata
  signature in lieu of an IMA file data signature in the measurement
  list, and adding dynamic debugging of EVM file metadata.

  In addition, in order to detect critical data or file change
  reversions, duplicate measurement records are permitted in the IMA
  measurement list.

  The remaining patches address compiler, sparse, and doc warnings"
