[GIT PULL] integrity subsystem updates for v5.19

[Mimi Zohar <zohar@linux.ibm.com>]

Hi Linus,

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.

thanks,

Mimi
