Merge tag 'integrity-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity

Pull IMA updates from Mimi Zohar:
 "New is IMA support for including fs-verity file digests and signatures
  in the IMA measurement list as well as verifying the fs-verity file
  digest based signatures, both based on policy.

  In addition, are two bug fixes:

   - avoid reading UEFI variables, which cause a page fault, on Apple
     Macs with T2 chips.

   - remove the original "ima" template Kconfig option to address a boot
     command line ordering issue.

  The rest is a mixture of code/documentation cleanup"
